Change Gain… ⌃G – Logic Pro X keyboard command of the day

Logic Pro X keyboard command of the day. #LogicProX @StudioIntern1

  Change Gain…   ⌃G

You can adjust the gain of the audio file, destructively. I use this command whenever I get an audio file that has a maximum gain of 0.0 dB – Logic can’t (or won’t) manipulate this audio in a non-destructive fashion, so I reduce it by .1 dB.

The key command is shared with “Normalize Region Gain” which I use all the time to adjust tracks to have peak values of -9 to -6 dB. The only time this would be counter-productive is when I get multi-tracks of a live performance. In these cases the peaks are performance coordinated. Use the Gain plugin across every track to lower the gain of everything equally – turn down the recording.

Remove DC Offset ⌃D – Logic Pro X keyboard command of the day

Logic Pro X keyboard command of the day. #LogicProX @StudioIntern1

  Remove DC Offset    ⌃D

I don’t recall ever seeing an audio file with DC on it, but I know how to remove it. Removing DC offset will present a dialog box indicating how much offset is found, and requiring you to confirm removal. In my case all I ever see is 0.00%, so I cancel.

Some audio interface hardware can layer direct current (DC) over the audio signal. This results in a vertical shift of the waveform position that can be clearly seen in the Audio File Editor. It can also cause crackling sounds at the start and end of the audio region during playback. Choose Functions > Remove DC Offset to center the waveform around the zero amplitude line.

Play/Stop Region from Anchor ⌃⇧→ – Logic Pro X keyboard command of the day

  Play/Stop Region from Anchor    ⌃⇧→

I rarely work in the Audio File Editor. My typical usage is to reduce the level of audio from 0.0 dB to something slightly less. I need to do this to get “Normalize Region Gain…” commands to work.

Anchor: Indicates the absolute start point of the audio file.

 Play audio files in the Audio File Editor – Logic Pro X

There are a number of playback options in the Audio File Editor. Playback of audio files in the Audio File Editor occurs independently of the project playhead position. To hear the audio file in the context of your arrangement, you should use the control bar buttons.

  Cycle Preview On/Off    ⌃C

There is a Preview button in the Audio File Editor, the Smart Tempo Editor, and the Project Audio window. When it is on and you press Play the selected audio will loop.

Selection Start and End to Previous Transient and Play ⌥⌘← – Logic Pro X keyboard command of the day

  Selection Start and End to Previous Transient and Play    ⌥⌘←

For that lightning-fast editing. Moves the selection (both start point and end point) to the previous transient and plays. At some point I will want to edit an audio file. This is a good place to start.

Most day-to-day audio editing tasks are performed in the main window and Audio Track Editor. The Audio File Editor is useful for removing pops and clicks in audio material, setting accurate crossover points for looped playback, correcting phase cancellation errors, and more.

Change Gain… ⌃G – Logic Pro X keyboard command of the day

Logic Pro X keyboard command of the day. #LogicProX @StudioIntern1

  Change Gain…   ⌃G

The keyboard command is overloaded with gain changing. In particular this command is used to change the gain of an audio file. It only functions when the Audio File editor is open.

NB when you open the “editor” window in the arrange window (click on the scissors icon) the editing panel opens with the “Track” editor chosen.

Changing gain in an audio file alters the file, hence a destructive change. Changing gain in a region is non-destructive.

I have only used the “Change Gain…” command when my attempts to “Normalize Gain” in regions fails to make a change. Typically I will normalize the gain of all of the regions/tracks to have peak levels of -12 dB to -6 dB. The only time I find this inappropriate is when I have a “live” recording where the band has performed the appropriate level-matching for the instruments/vocals.

When normalizing gain I occasionally find regions that do not change. This happens when the maximum level in the audio file is 0 dB. Logic won’t adjust it. I don’t know if this is a bug or a feature. Clearly I have no use for audio files at 0 dB peak, so I adjust the audio file -0.1 dB (relative) which lowers the maximum from 0 dB. At this point the normalize gain commands will actually change region gain as I wish.

The “Apply Normalize Region Gain Again” command is also assigned to ⌃G. This is active whenever the arrange window is open, as well as in the Audio Track Editor.

You can use the Change Gain command to change the level of an audio file in the Audio File Editor. Typically used on an entire audio file, this command can also be used to boost portions of it.

Save Selection As… ⌥⌘S – Logic Pro X keyboard command of the day

  Save Selection As… ⌥⌘S

Located in the Audio File Editor.

Select a portion of an audio file (e.g. a kick drum hit) and save it as an audio file. Guess it can come in handy.

Important: Most edits and functions performed in the Audio File Editor are destructive. This means the actual data of audio files is changed. Although you can undo edits and processing commands, you should work with copies of your audio files, rather than the originals.
