how to take under control my db headroom under Audacity?

hello I’m new in Audacity, I wish to ask you how to take under control my db if I mix in multi track?

If I’m playng with the Audacity mixer doeas exist a method to create groups and contol all the faders at the same time (like in pro tools)?
does exist a way to create a master fader?
does exit a way to create stems?

thx so much. :slight_smile:

No, that would be a feature request.

No, that would be another feature request, though you can apply the same amount of amplification to all, or a subset of tracks by selecting those tracks and applying the Amplify effect, or (as I prefer to do):

  • Select the tracks that you want for the sub-mix,
  • Tracks menu > Mix and Render to New Track
  • Mute the original tracks (or export them as 32 bit float WAV files and delete them from the project).

Just adding to what Steve said… Audacity itself works in floating-point, so it essentially has infinite headroom.

If you render/export to 32-bit WAV, you also have nearly infinite headroom. You can re-import the floating-point WAV mix and normalize it to 0dB, then export again to your desired final format.

If you want a DAW that’s cheaper than Pro Tools, look into [u]REAPER[/u] ($60 USD for hobby & small business use). But if you already have Pro Tools or, if you are familiar with Pro Tools and you don’t want to deal with a new learning curve, Pro Tools may be the answer for you.
