Topic: Audacity "amplify" does not produce equal amplitude

[page]

in your example, I want to amp the first one by 4db and the second one to 5. Those are the numbers that are pre-populated when I pull up the amplify function when selecting just those tracks.

Did I miss something?

page,

for that clip i amplified both channels to -4 dB.  you're saying you're seeing a 1 dB discrepancy?

Yep. The left channel peaks at -4, the right channel at -5 in the sample, so the gain required to get to 0 from here is different.

My guess is you accidentally ran the amplify function for both channels and which would produce uniform game for a track that has different peak values. If I run them one at a time, I get different default values to produce a 0db peak.

So if you try and amplify that sample to lets say -2, do you only apply 2db to each channel or do you apply 2 on the left and 3 on the right? (open amplify on each track after doing so and you'll see the new amount of gain needed to get to 0 which is the default setting).

Same results as page - Is it possible you bumped the + - gain slider - making the file render unevenly - despite using Amplify for gain change...(screen shot looks like sliders a not centered)

EDIT - this has to be what happened - I was able duplicate this effect - reduce one channel by 1db. Then run amplify on each channel...make stereo track > export...resulting file has one channel -1db lower than the other.

So - adjustments made using the slider arent applied until you Export...

Thanks for looking at this, guys.  I really appreciate it.  I guess I got sloppy.  Note to self:  Do not work on files when tired.
