ADOBE AUDITION 267 User Guide Mute Block This command mutes or unmutes the selected blocks. This command is different than Track Muting (which occurs when you press the Mute button in the Track Console area), which disables all waveforms within a track. Muted blocks are ignored during playback and mixdowns, and are displayed as "grayed-out". Lock in Time Lock In Time "locks" selected waveforms to their current time location in the multitrack session. Locking a waveform is useful when you've decided upon its position in time, and don't want to accidentally move the waveform when right-clicking on it. Locked waveforms are identified by an overlaid graphic of a circled padlock. While a waveform which has been locked can't be moved in time (left or right), it may be vertically repositioned, allowing you to move it between tracks. To unlock a waveform, simply select it and choose Lock in Time to free it for horizontal movement. Lock for Play Only This command disables the ability of a waveform block to be recorded into. Even though the track that the playback-locked block resides in may be record-enabled (it has the red "R" button on the Track Console depressed), the marked waveform will not be recorded over. This is signified by the waveform block not turning red when the track is record-enabled. Split The Split command functions similarly to a traditional tape splice; it "cuts" the waveform, segmenting it into parts. The cut is performed at the current cursor point, or selection (in this case the selection will be spliced out). Once a block has been split, each segment can be moved, deleted, or slid in time independently of the other segments. Splitting a waveform is non-destructive, it does not alter the waveform on disk. Merge/Rejoin Split Merge/Rejoin Split recombines a split segment of a waveform block with the original surrounding material, provided that the split segment sits at the same relative location as where it was split from, and in the same track as the original segment(s). The boundaries of the segments are joined together using a 30 millisecond crossfade. The Merge/Rejoin Split command can also be used to rejoin a take created using Punch In to the rest of the waveform. Note: This merge operation is destructive in that it does alter your sound file (when rejoining a Punch In segment, the file is rewritten with the new material, for example). Align Left The Align Left command (which is only accessible if two or more blocks are highlighted) to make the lefthand edges of all highlighted blocks the same as the left-hand edge of the last highlighted block. Align Right Click the Align Right command (which is only visible when two or more blocks are highlighted) to make the right-hand edges of all highlighted blocks the same as the right-hand edge of the last block you highlighted. Adjust Boundaries This function will adjust the boundaries of the selected waveform block either inwardly or outwardly. After highlighting to define an area to adjust to, any material in the waveform block that lies within this highlight will be retained or exposed, removing that which is outside of the highlight (or including material inside the selection that is not currently revealed). For example, with a 5 second waveform block, highlighting the middle second and choosing Adjust Boundaries will trim off the surrounding material (the first two seconds and the last two seconds), leaving just the middle second. If you decide you've trimmed off too much, you can highlight the middle second plus a little to the right, for instance, and again choose Adjust Boundaries to bring back that little bit to the right, thereby lengthening the waveform block.
