Replacing Audio Regions

(TDM Systems Only)

You can use the Replace Region function to replace multiple instances of an audio region in a playlist with another region that you Controldrag (Windows) or Command-drag (Macintosh) from the Regions List.

Replace Region dialog

This is useful in post production if you use a sound effect, room noise, or atmosphere region many times in a session, and later decide to replace one or all of the original regions with a different region.

This is also useful in music production if you want to replace a certain loop or sample (for example, a drum beat) with a new one. You can use this compositionally, if you know the tempo of a section or session, to create a scratch piece with “rough” regions of the correct length, and later replace them with “final” regions of the same length.

The following options are available in the Replace Region dialog:

Replace Original Region Replaces only the selected region with the replacement region dragged from the Regions List.

Replace All Regions That Match Original Replaces all regions that fit the Match criteria and the Find Match On criteria with the replacement region from the Regions List.

Match: Start Position Replaces all regions that have the same original start time as the selected region. This includes regions that may have been auto-created when trimming end points.

Chapter 18: Advanced Editing (TDM Systems Only) 303

Match: End Position Replaces all regions that have the same original end time as the selected region. This includes regions that may have been auto-created when trimming start points.

Match: Region Name Replaces all regions that have the same name as the selected region.

Region matching uses all specified Match criteria. For example, if you select Start Position and

End Position, all regions from the same original audio file as your selection with the same original start and end times will be replaced.

Find Match On: This Track Only Replaces regions that fit the Match criteria and are on the same track as the original region.

Find Match On: All Tracks Replaces regions that fit the Match criteria for all tracks in the session.

Fit To: Original Region Length If the replacement region is smaller than the original region, the region is placed in the playlist and any remaining audio from the original region is removed.

If the replacement region is larger than the selection, it is placed in the playlist and trimmed to fit within the length of the original region.

Fit To: Original Selection Length When the playlist selection extends beyond the original region, the replacement region (if larger than the original region) is trimmed to fit within the selection.

Fit To: Replacement Region Length The replacement region is placed in its entirety, regardless of the length of the original region or selection.

The Replace Region function only works on a selection that includes a single region on one track. The function is not available when the playlist selection includes the start points for two or more regions. Also, if the selection is across several tracks, only the selection in the first (top) track is used.

To replace regions:

1 Select a region in a track’s playlist that you want to replace. The selection can extend beyond the region’s end point, to include material from the replacement region that is longer than the original region.

2 Control-drag (Windows) or Command-drag

(Macintosh) the replacement region from the

Regions List to the selected region. The Replace

Region dialog opens.

3 If you want to replace only the original region, select Replace Original Region.

– or –

If you want to replace multiple regions, select

Replace All Regions That Match Original, and set the Match criteria.

4 Select whether to apply the replacement to all tracks, or only to the track with the current selection.

5 Select whether to fit the replacement regions to the current selection, the entire region, or the entire replacement region regardless of the destination length.

6 When you have set all the options, click OK.

Replace Region and Multichannel

Tracks

The Replace Region command supports dragging multichannel regions from the Audio Regions List to multichannel tracks, provided they are the same format.

For example, you can replace a stereo region, selected in a stereo audio track, with another stereo region from the Audio Regions List. But you cannot replace it with two mono audio regions.

In addition, replacing regions in multiple mono tracks with multichannel regions is not supported.

To fill a selection with Paste to Fill:

1 Select the audio or MIDI region you want to copy and choose Edit > Copy.

2 Select the area you want to fill using the Selector and choose Edit > Repeat Paste To Fill Selection.

3 If pasting audio regions to larger areas, the

Batch Fades dialog opens. Configure the dialog to insert crossfades between each pasted region, then click OK.

– or –

If you do not want crossfades for the pasted audio, click Cancel in the Batch Fades dialog.

Repeat Paste To Fill Selection

(TDM Systems Only)

The Repeat Paste To Fill Selection command allows you to automatically fill a selection with audio or MIDI data without requiring you to duplicate the regions manually. To use Repeat

Paste, copy an audio or MIDI region, then make a selection and use the command to fill the selection. When pasting audio regions, you are prompted to specify a crossfade to be used for the pasted regions.

If you fill an area that is an exact multiple of the copied region size (for example, filling 16 bars with a 4-bar loop), the copied selection is pasted in exactly as many times as it takes to fill the selection. If you fill an area that is not an exact multiple of the copied region size (for example, filling 15 seconds of a track with a 2-second atmosphere or room noise region), the remaining selection area is filled with an automatically trimmed version of the original selection.

Compress/Expand Edit To

Play

(TDM Systems Only)

When the Edit and Timeline selections are unlinked, you can compress or expand an audio selection to fit the Timeline selection. This feature works by using the Time Compression/Expansion plug-in to expand or compress the selected audio material.

To fit an Edit selection to the Timeline:

1 Deselect Operations > Link Edit and Timeline

Selection.

2 With the Selector, select the audio material to be compressed or expanded.

3 In any Timebase Ruler, select the time range where you want to fit the audio material.

4 Choose Edit > Compress/Expand Edit To Play.

The Edit selection is compressed or expanded to the length of the Timeline selection.

Compress/Expand Edit to Play on

Multiple Tracks and Channels

The Compress/Expand Edit to Play command can be used on multichannel selections, and selections across multiple tracks.

However, all regions are compressed or expanded equally by the same percentage value, based on Edit selection range. This ensures that the rhythmic relationship between the different channels or tracks is retained.

Fit to Selection on Multiple Tracks and

Channels

The Fit to Selection command supports dragging multiple regions from the Audio Regions

List to multiple tracks, or multichannel tracks.

However, all dragged regions are compressed or expanded equally by the same percentage value, based on length of the region last clicked before dragging.

Fitting an Audio Region to an Edit

Selection

Regions can be dragged from the Audio Regions

List to fit within an Edit selection. The dragged region is compressed or expanded to fit within the selection. This feature uses the Time Compression/Expansion plug-in to expand or compress the audio region.

To fit an audio region to an Edit selection:

1 With the Selector, select a time range in an audio track.

2 Control-Alt-drag (Windows) or Command-

Option-drag (Macintosh) the region from the

Audio Regions List to the track with the selection. The start of the region is positioned at the selection start, and the region is compressed or expanded to match the length of the selection.
