It includes an Analysis section, that lets you know what the resulting level will be after the Gain is changed (typically to avoid overloads).
Gain is a fancier version of that same Trim plug-in. This can also be done with the Phase button in the real-time Trim plug-in, but a permanent fix here frees up a plug-in slot. This can correct for a recording made with a mis-wired cable, or for acoustic issues (the bottom mic on a snare drum needs to be flipped to put that signal in “phase” with the top mic). Invert simply flips the polarity of the file (positive/negative). If that’s happening, and you suspect an Offset, this plug-in will scan the file and correct for it, making normal clean edits possible. DC-Offset is an audio artifact that’s often too small to be noticed when viewing the wave, but can cause clicks when you make an edit (even during silence). DC-Offset Removal is a problem solver, though for what’s probably an infrequent problem these days. The new audiofile will be a duplicate of just the raw audio data, unaffected by any channel strip settings (volume/pan/automation) or plug-in processing (Bounce-to-Disk would include all those settings, unless you zero/bypass them).
Duplicate is a quick and easy way to make a copy of the audio in a selection, and drop the copy into the Clip List or Playlist. In the AudioSuite menu’s “Other” sub-menu, you’ll find six utility plug-ins.
Most are simple utilities (sometimes with additional features added to equivalent real-time options), and a couple offer creative processing. There are eight of these: Duplicate, DC-Offet Removal, Invert, Gain, Normalize, Reverse, Time Shift, and Vari-Fi. Fig 1 Pro Tools’ AudioSuite-only plug-ins.
