The Pool
Toolbar overview
The info line
Click the “Show Info” button on the toolbar to show or 
hide the info line at the bottom of the Pool window. It 
shows the following information:
How clips are displayed in the Pool
 Audio clips are represented by a waveform icon followed by 
the clip name.
 Video clips are represented by a camera icon followed by the 
clip name.
The Pool window columns
Various information about the clips can be viewed in the 
Pool window columns. The columns contain the following 
information:
About the Status column symbols
The Status column can display various symbols that relate 
to the clips status. The following symbols can be shown:
Sorting the Pool contents
You can sort the clips in the Pool by name, date etc. This 
is done by clicking on the corresponding column heading. 
Clicking again on the same heading switches between as-
cending and descending sort order.
Column Description
Media This column contains the Audio, Video and Trash folders. 
If the folders are opened, the clip names are shown and 
can be edited. This column is always shown.
Used This column displays the number of times a clip is used in 
the project. If a column row is empty, the corresponding 
clip is not used.

rent Pool and clip status. See “About the Status column 
symbols” on page 131 for a description of the icons.
Musical The checkbox in this column allows you to activate or de-
activate Musical Mode. If the Tempo column (see below) 
displays “???”, you have to enter the correct tempo be-
fore you can activate Musical Mode.
Tempo This shows the tempo of audio files for which a tempo 
has been set using the Audio Tempo Definition tool. If no 
tempo has been specified, the column displays “???”. 
Sign. This is the time signature, e. g. “4/4”.
Info This column shows the following information for audio 
clips: The sample rate, bit resolution, number of channels 
and the length in seconds. For video clips the frame rate, 
number of frames, and length in seconds are shown.
Type This column shows the file format of the clip.
Date This column shows the date when the clip was created.
Origin Time This column shows the original start position where a clip 
was recorded in the project. As this value can be used as 
a basis for the option “Insert into Project” in the Media or 
context menu (and other functions), you can change it if 
the Origin Time value is independent.
Image This column displays waveform images of audio clips. 
Path This column shows the path to the location of a clip on 
the hard disk.
Symbol Description
This indicates the current Pool Record folder (see 
“Changing the Pool Record folder” on page 138).
This symbol is shown if a clip has been processed.
The question mark indicates that a clip is referenced to 
the project but is missing from the Pool (see “About mis-
sing files” on page 135).
This indicates that the clip file is external, i.e. located out-
side the current Audio folder for the project.
This indicates that the clip has been recorded in the cur-
rently open version of the project. This is useful for finding 
recently recorded clips quickly. Column Description

The Pool
Customizing the view
You can specify which of the columns should be shown 
or hidden by selecting the View/Attributes pop-up on the 
toolbar and selecting/deselecting items.
You can rearrange the order of the columns by clicking 
on a column heading and dragging the column to the left 
or right.
The mouse pointer changes to a hand when you place it on the column 
heading.
The width of a column can also be adjusted by placing 
the pointer between two column headers and dragging 
left or right.
The pointer changes to a divider when you place it between two column 
headers.
Operations
Renaming clips in the Pool
To rename a clip in the Pool, select it and click on the ex-
isting name, type in a new name and press [Return].
ÖThis will also rename the referred files on disk!
Copying clips in the Pool
To make a duplicate clip, proceed as follows:
1.Select the clip you wish to copy.
2.Select “New Version” on the Media or context menu.
A new version of the clip appears in the same Pool folder, with the same 
name but with a “version number” after it, to indicate that the new clip is 
a duplicate. The first copy made of a clip will logically get the version 
number “2” and so on. 
Inserting clips into a project
By using menus
1.Select the clip(s) you want to insert into the project.
2.Pull down the Media or context menu and select an 
“Insert into Project” option.
The “At Cursor” option will insert the clip(s) at the current project cursor 
position. 
The “At Origin” option will insert the clip(s) at their Origin Time position(s).
Note that the clip will be positioned so that its snap 
point is aligned with the selected insert position.
You can also open the Sample Editor for a clip by double-clicking it, and 
perform the insert operation from there. This way you can set the snap 
point before inserting a clip.
The arrow indicates the sort 
column and sort order.
!Renaming a clip in the Pool is much preferred to re-
naming it outside Cubase LE (for example on the 
computer desktop). This way Cubase LE already 
“knows” about the change, and won’t lose track of 
the clip the next time you open the project. See 
“About missing files” on page 135 for details about 
lost files.
!Copying a clip does not create a new file on disk, but 
just a new edit version of the clip (referring to the 
same original file). 
						

							133
The Pool
3.The clip is inserted on the selected track or on a new 
audio track.
If several tracks are selected, the clip will be inserted on the first selected 
track.
By using drag and drop
You can use drag and drop to insert clips into the Project 
window. You can also use drag and drop from the Sample 
Editor for a clip by making a selection range and pressing 
[Ctrl]/[Command] while dragging. Note:
Snap is taken into account if activated.
While you drag the clip in the Project window, its posi-
tion will be indicated by a marker line and a numerical po-
sition box.
Note that these indicate the position of the snap point in the clip. For ex-
ample, if you drop the clip at the position 10.00, this will be where the 
snap point ends up. See “Adjusting the snap point” on page 110 for in-
formation on how to set the snap point.
If you position the clip in an empty area in the event dis-
play (i.e. below existing tracks), a new track is created for 
the inserted event.
Deleting clips
Removing clips from the Pool
To remove a clip from the Pool without deleting it from the 
hard disk, proceed as follows:
1.Select the clip(s) and select “Delete” from the Edit 
menu (or press [Backspace] or [Delete]).
ÖIf you try to delete a clip that is used by one or more 
events, the program will ask you if you want to remove 
these events from the project.
If you cancel, neither the clip nor the associated events are deleted.
2.Click Remove.
A new prompt asks whether you want to move the clip to the Trash or re-
move it from the Pool.
3.Select “Remove from Pool”.
The clip is no longer associated with the project, but still exists on the 
hard disk and can be used in other projects etc. This operation can be 
undone.
Deleting from the hard disk
To delete a file permanently from the hard disk, it must first 
be moved to the Trash folder:
1.Follow the instructions for deleting clips above and se-
lect “Trash”.
Alternatively, you can drag and drop clips into the Trash folder.
2.Select “Empty Trash” on the Media or context menu. 
Choose one of the two options in the alert: 
Click “Erase” to delete the file on the hard disk perma-
nently.
Remember that this operation cannot be undone!
Click “Remove from Pool” to remove the clip from the 
Pool but to keep the file.
Snap point
!Before you permanently delete audio files from the 
hard disk, make sure that they are not used by an-
other project! 
						

							134
The Pool
ÖTo retrieve a clip from the Trash Folder, drag and drop 
it back into an Audio or Video folder.
Removing unused clips from the Pool
This function finds all clips in the Pool that are not used in 
the project. You can then decide whether to move them to 
the Pool Trash folder (where they can be permanently de-
leted) or to remove them from the Pool:
1.Select “Remove Unused Media” on the Media or con-
text menu.
A prompt appears with the text “Move to Trash or Remove From Pool?”
2.Make your selection.
Locating events and clips
Locating events via clips in the Pool
If you want to find out which events in the project refer to a 
particular clip in the Pool, proceed as follows:
1.Select one or more clips in the Pool.
2.Select “Select in Project” on the Media or context 
menu.
All events that refer to the selected clip are now selected in the Project 
window.
Locating clips via events in the Project window
If you want to find the clip for an event in the Project win-
dow, proceed as follows:
1.Select one or more events in the Project window.
2.Pull down the Audio menu and select “Find Selected 
in Pool”.
The corresponding clip(s) will be located and highlighted in the Pool. If 
the Pool window isn’t already open it will be opened.
Searching for audio files
The Pool can help you locate audio files in your Pool, on 
your hard disk or other media. This works much like the 
regular file search, but with a couple of extra features:
1.Click the Search button in the toolbar.
A search pane appears at the bottom of the window, displaying the 
search functions.
The search pane in the Pool.
By default, the search parameter in the search pane is “Name”. For us-
ing other filter criteria, see “Extended search functionality” on page 135 
below.
2.Specify the name of the file(s) to search for in the 
Name field.
You can use partial names or wildcards (*). Note that only audio files of 
the supported formats will be found.
3.Use the Location pop-up menu to specify where to 
search.
The pop-up menu will list all your local drives and removable media. 
If you want to limit the search to certain folders, choose 
“Select Search Path” and select the desired folder in the 
dialog that appears.
The search will include the selected folder and all subfolders. Note also 
that folders you have recently selected using the “Select Search Path” 
function will appear on the pop-up menu, allowing you to quickly select 
any of them.
4.Click the Search button.
The search is started and the Search button is labeled Stop – click this 
to cancel the search if needed.
When the search is finished, the found files are listed to 
the right.
To audition a file, select it in the list and use the play-
back controls to the left (Play, Stop, Pause and Loop).
If Auto Play is activated, selected files will automatically be played back.
To import a found file into the Pool, select it in the list 
and double-click it or click the Import button.
5.To close the search pane, click the Search button in 
the toolbar again. 
						

							135
The Pool
The Find Media window
Alternatively to the search pane in the Pool, you can open 
a stand-along Find Media window by selecting the 
“Search Media…” option from the Media or context menu 
(also available from the Project window). This offers the 
same functionality as the search pane. 
To insert a found clip directly into the project from the 
Find Media window, select it in the list in the dialog and 
select one of the “Insert into Project” options from the Me-
dia or context menu.
The options are described in “Inserting clips into a project” on page 132.
Extended search functionality
Apart from the search criterion Name, additional search fil-
ters are available. To use them, proceed as follows:
1.Click the Search button on the toolbar.
The Search pane is displayed in the lower part of the Pool window.
2.Move the mouse pointer over the “Name” text to the 
right of the name field, until an arrow is displayed, and 
click it.
3.The Extended Search pop-up menu opens.
This contains six options determining which search criteria will be dis-
played above the Location (Name, Size, Bitsize, Channels, Sample Rate 
or Date) and the Add Filter and Presets submenus.
The search criteria have the following parameters:
 Name: partial names or wildcards (*)
 Size: Less than, more than, equal, between (two values), in 
seconds, minutes, hours and bytes
 Bitsize (resolution): 8, 16, 24, 32
 Channels: mono, stereo and from 3 to 16
 Sample Rate: various values, choose “Other” for free setting
 Date: various search ranges
4.Select one of the topmost 6 options in the pop-up 
menu to change the search option above the Location 
pop-up menu.
This way, you can choose e. g. to display the Size or Sample Rate para-
meter instead of the Name field.
5.If you want to display more search options, select the 
desired element from the Add filter submenu.
This allows you e. g. to add the Size or the Sample Rate parameters to 
the already displayed Name and Location parameters.
This allows for a very detailed search, helping you to mas-
ter even the largest sound database.
You can store presets of your search filter settings. For 
this, click Store Presets in the Presets submenu and enter 
a name for the preset.
Existing presets will be offered at the bottom of the list. To remove a 
preset, click on the preset to activate it, then choose Remove Preset.
About missing files
When you open a project, the Resolve Missing Files dialog 
(see below) may open, warning you that one or more files 
are “missing”. If you click Close in the warning dialog, the 
project will open anyway, without the missing files. In the 
Pool you can check which files are considered missing. 
This is indicated by a question mark in the Status column.
Move the mouse pointer over the “Name” text to 
the right of the name field and click…
… to show the Extended Search pop-up menu. 
						

							136
The Pool
A file is considered missing under one of the following 
conditions:
The file has been moved or renamed outside the pro-
gram since the last time you worked with the project, and 
you ignored the Resolve Missing Files dialog when you 
opened the project for the current session.
You have moved or renamed the file outside the pro-
gram during the current session.
You have moved or renamed the folder in which the 
missing files are located.
Locate missing files
1.Select “Find Missing Files” from the Media or context 
menu.
The Resolve Missing Files dialog opens. 
2.Decide if you want the program to try to find the file for 
you (Search), if you want to do it yourself (Locate) or if you 
want to specify in which directory the program should 
search for the file (Folder).
If you select Locate, a file dialog opens, allowing you to 
locate the file manually.
Select the file and click “Open”.
If you select Folder, a dialog opens to let you specify the 
directory in which the missing file can be found.
This might be the preferred method if you have renamed or moved the 
folder containing the missing file, but the file still has the same name. 
Once you select the correct folder, the program finds the file and you can 
close the dialog.
If you select Search, a dialog opens to let you specify 
which folder or disk should be scanned by the program. 
Click the Search Folder button, select a directory or a disk and click the 
Start button. If found, select the file from the list and click “Accept”. 
Afterwards Cubase LE tries to map all other missing files automatically.
Reconstructing missing edit files
If a missing file cannot be found (e. g. if you have acciden-
tally deleted it from the hard disk), it will normally be indi-
cated with a question mark in the Status column in the 
Pool. However, if the missing file is an edit file (a file cre-
ated when you process audio, stored in the Edits folder 
within the project folder), it may be possible for the pro-
gram to reconstruct it by recreating the editing to the orig-
inal audio file:
1.Open the Pool and locate the clip(s) for which files are 
missing.
2.Check the Status column – if it says “Reconstruct-
ible”, the file can be reconstructed by Cubase LE.
3.Select the reconstructible clips and select “Recon-
struct” from the Media or context menu.
The editing is performed and the edit files are recreated.
Removing missing files from the Pool
If the Pool contains audio files that cannot be found or re-
constructed, you may want to remove these. For this, select 
“Remove Missing Files” from the Media or context menu. 
This will remove all missing files from the Pool as well as 
their corresponding events from the Project window.
Auditioning clips in the Pool
There are two methods you can use to audition clips in the 
Pool:
By selecting a clip and activating the Play button.
The whole clip will play back, unless you stop playback by clicking the 
Play button again.
The Play button. 
						

							137
The Pool
By clicking somewhere in the waveform image for a clip.
The clip will play from the position in the waveform you click until the end 
of the clip, unless you stop playback by clicking the Play button, or by 
clicking anywhere else in the pool window.
Click in the waveform image to audition a clip.
You can adjust the auditioning level with the miniature 
level fader on the toolbar. This does not affect the regular 
playback level.
If you have activated the Loop button before you audition, 
the following will happen:
The Loop button.
If you click the Play button to audition a clip, it will repeat 
indefinitely until you stop playback by clicking the Play or 
Loop button again.
If you click in the waveform image to audition, the sec-
tion from the point you clicked to the end of the clip will re-
peat indefinitely until you stop playback.
Opening clips in the Sample Editor
The Sample Editor allows you to perform detailed editing 
on the clip (see “The Sample Editor” on page 106). 
If you double-click on a clip waveform icon or a clip name 
in the Media column, the clip will open in the Sample 
Editor.
One practical use for this is to set a snap point for a clip 
(see “Adjusting the snap point” on page 110). When you 
later insert the clip from the Pool into the project, you can 
have it properly aligned according to the set snap point.
Import Medium...
The Import Medium dialog lets you import files directly into 
the Pool. It is opened from the Media or context menu or 
with the Import button in the Pool window.This is a standard file dialog, where you can navigate to 
other folders, audition files etc. The following audio file for-
mats can be imported:

 AIFF and AIFC (Compressed AIFF)
“Importing ReCycle files” on page 240)
 SD2 (Sound Designer II) 
 MPEG Layer 2 and Layer 3 (mp2 and mp3 files – see “Impor-
ting compressed audio files” on page 241)
 Windows Media Audio (Windows – see “Importing com-
pressed audio files” on page 241)
They may have the following characteristics:

 Any sample rate (although files with another sample rate than 
the one used in the project will play back at the wrong speed 
and pitch – see below).
 8, 16, 24 bit or 32 bit float resolution
The following videos formats can also be imported:
 AVI (Audio Video Interleave)
 MOV and QT (QuickTime)

 MPEG 1 and 2 video files
!For video files to be played back correctly, the right 
codecs have to be installed.
Clicking the Import button opens the Import dialog: 
						

							138
The Pool
ÖIt is also possible to use the commands on the Import 
submenu on the File menu to import audio or video files 
into the Pool.
When you select a file in the Import Medium dialog and 
click Open, the Import Options dialog opens:
It contains the following options:
Copy File to Working Directory.
Activate this if you want a copy of the file to be made in the Audio folder 
of the project, and have the clip refer to this copy. If the option is off, the 
clip will refer to the original file in the original location (and will thus be 
marked as “external” in the Pool – see “About the Status column sym-
bols” on page 131).
Convert to Project section:
Here you can choose to convert:
 the sample rate (if the sample rate is different than the one set for 
the project
)
 the sample size, i. e. resolution (
if the sample size is lower than the 
record format used in the project)
The options are only available if necessary. Note that if you are importing 
several audio files at once, the Import Options dialog will instead contain 
a “Convert if needed” checkbox. When this is activated, the imported 
files will be converted only if the sample rate is different or the sample 
size is lower than the project’s.
Do not Ask again.
If this is activated, files will always be imported according to the settings 
you have made, without this dialog appearing. This can be reset in the 
Preferences (Editing–Audio page). 
ÖYou can always convert files later by using the Convert 
Files (see “Convert Files” on page 140) or Conform Files 
(see “Conform Files” on page 140) options.
Changing the Pool Record folder
The Pool Record folder.
In the Pool Record folder, all audio clips that you record in 
the project will end up. The Pool Record folder is indi-
cated by the text “Record” in the Status column and by a 
red dot on the folder itself, as shown in the picture above. 
By default, this is the main Audio folder. You can, how-
ever, at any time create a new Audio subfolder and desig-
nate this as your Pool Record folder. Proceed as follows:
1.Select the Audio folder or any audio clip.
You cannot designate the Video folder (or a subfolder in it) as the Pool 
Record folder.
2.Select “Create Folder” on the Media or context menu.
A new empty audio subfolder appears in the Pool.
3.Select the new folder.
4.Select “Set Pool Record Folder” on the Media or con-
text menu, or click in the Status column of the new folder.
The new folder now becomes the Pool Record folder, and any audio re-
corded in the project will be saved in this folder.
Organizing clips and folders
If you accumulate a large number of clips in the Pool, it 
may sometimes be difficult to quickly find specific items. In 
such cases, organizing clips in new subfolders with suit-
able names that reflect the content can be a solution. For 
example, you could put all sound effects in one folder, all 
lead vocals in another etc. Proceed as follows:
1.Select the type of folder, audio or video, for which you 
want to create a subfolder.
You cannot put audio clips in a video folder and vice versa.
2.Select “Create Folder” on the Media on context menu.
A new empty subfolder named “New Folder” appears in the Pool.
3.Click on the name and enter an appropriate name for 
the folder.
4.Drag and drop the clips you wish to move to the new 
folder.
5.Repeat steps 1-4 as necessary.

The Pool
Applying processing to clips in the Pool
You can apply audio processing to clips from within the 
Pool in the same way as to events in the Project window. 
Simply select the clip(s) and choose a processing method 
from the Audio menu. To find out more about audio pro-
cessing, see “Audio processing and functions” on page 
100.
Undo processing
If you have applied processing to a clip, either in the 
Project window or in the Pool, this is indicated by the red 
and grey waveform symbol in the Status column.
Freeze Edits
You can use the Freeze Edits function to create a new file 
with processing applied or to replace the original with a 
processed version, see “Freeze Edits” on page 105.
Minimize File
The option “Minimize File” on the Media or context menu 
allows you to change the size of audio files according to 
the audio clips referenced in a project. The files produced 
using this option will only contain the audio file portions 
actually used in the project. This can significantly reduce 
the size of the project, if large portions of the audio files 
are unused. Therefore, the option is useful for archiving 
purposes after you have completed a project.
ÖThis operation will permanently alter the selected au-
dio files in the Pool. This cannot be undone!
If this is not what you want, you can use the option “Save Project to New 
Folder” in the File menu instead, see “Save Project to New Folder” on 
page 238. This function also has the option of minimizing files, but cop-
ies all files into a new folder, leaving the original project untouched.
Proceed as follows:
1.Select the file(s) you wish to minimize in the Pool.
2.Select “Minimize File” on the Media or context menu.
An alert appears, informing you that the entire Edit History will be 
cleared. Click Minimize to proceed or Cancel to stop the process. 
3.After the minimizing is finished, another alert appears, 
because the file references in the stored project have be-
come invalid. 
Click Save Now to save the updated project or click Later to proceed 
with the unsaved project. 
Only the audio portions actually used in the project remain 
in the corresponding audio file(s) in the Pool Record folder.
Prepare Archive
The option “Prepare Archive” on the Media or context 
menu is useful if you want to archive a project. It checks 
that every clip referenced in the project is located in the 
same folder, and takes actions if that is not the case: 
Any files that are located outside the current project 
folder will be copied to it.
Please note that audio files that reside within the project folder will not be 
copied to the audio folder. You will therefore have to copy them there 
manually before backing up the audio folder or save them separately dur-
ing backup, see below.
If any processing has been applied, you will be asked 
whether you want to Freeze Edits.
If you do this, you don’t have to archive the Edits folder. Everything belong-
ing to the project will be contained in the project file and the Audio folder.
Once you have performed a Prepare Archive, you can copy 
the project file, the Audio folder and any other audio mate-
rial you saved in the project folder to backup disks, etc.
It is not necessary to archive the Images folder, since 
these Images can be recreated by Cubase LE. You may 
also find a file with the extension “.csh” in the project 
folder. This contains image information for edited clips and 
other data that can be recreated, so it can safely be de-
leted.
!Video clips are always referenced and not stored in 
the project folder.

The Pool
Convert Files
Selecting the option “Convert Files” on the Media or con-
text menu opens the Convert Options dialog which oper-
ates on selected files. Use the pop-up menus to specify 
which audio file attributes you want to keep and which you 
want to convert. The available settings are:
Sample Rate
Keep as is, or convert to a sample rate between 8.000 and 96.000 kHz.
Sample Width
Keep the sample width (resolution) as is, or convert to 16 bit, 24 bit or 
32 Bit float.
Channels
Keep as is, or convert the file to Mono or Stereo Interleaved.
File Format
Keep as is, or convert to Wave or AIFF format.
Options
When you convert a file, you can use the Options pop-up 
to set one of the following options regarding what to do 
with the new file:
Conform Files
By using this Media or context menu command, you will 
change all selected files that have different file attributes 
than what is specified for the project, to conform to this 
standard.
Proceed as follows:
1.Select the clips in the Pool.
2.Select “Conform Files” on the Media or context menu.
A dialog opens allowing you to choose between keeping or replacing the 
original unconverted files in the Pool. The following applies:
 Clip/event references in the pool are always redirected to the 
conformed files.
 If any keep option is selected, original files remain in the 
Project’s Audio folder and new files are created.
 If you select the “Replace” option, files in the Pool and in the 
Project’s Audio folder are replaced.
Option Description
New Files Creates a copy of the file in the audio folder and converts 
this new file according to the chosen attributes. The new 
file is added to the Pool, but all clip references will still 
point to the original, unconverted file.
Replace Files Converts the original file without changing clip refer-
ences. The references are however saved with the next 
save action.
New + Replace 
in PoolCreates a new copy with the chosen attributes, replaces 
the original file with the new one in the Pool and redirects 
the current clip references from the original file to the 
new file. This is the option to select if you want your audio 
clips to refer to the converted file, but still want to keep 
the original file on disk (e. g. if the file is used in other 
projects).
