multiple tracks volume adjustment

[jlbisme]

I will be putting about 20 tracks on one CD. How do I adjust volume for each track so volume is consistent for all?

Thanks!

With all the tracks underneath each other in Audacity, you can select them all (CTRL + A) then Effect > Normalize, but this may unbalance the individual channels in each track, assuming they are stereo, because the peak in each channel is calculated separately. If the stereo balance requires correction (it may do if you recorded with cheap hardware), then you can use Normalize if you are sure to use Effect > Click Removal first to get rid of any clicks.

To be sure the stereo balance is unchanged, select each track in turn and Effect > Amplify to the New PeaK Amplitude you want.

If the tracks for the CD are in one Audacity track, select then label each track (CTRL + B), then click in the label to select each track in turn and Effect > Amplify (or Normalize if you need to correct stereo balance).

Note that running these effects do not make the selections equally loud in terms of how you may hear the tracks. You need to run Replay Gain on the tracks outside of Audacity if you want to make them "equally loud". You can approximate this in Audacity by making the area of light blue (average volume) in each track about the same, using Envelope Tool (F2).
