Audacity Forum

The solution I came up with: Rather than running a bazillion experiments to get each of 62 episodes tweaked to the point its MP3 files meets specs, I simply got a copy of Adobe Audition and edited the MP3 files directly. I spent way too many hours messing around with this, so mostly I'm still shakin...

I also tried converting the mono track to stereo, then normalizing it. But when I export, I get the same problem.

Another thing I'm seeing is that after -7 dB normalization, is that the average level is now too low, but the peaks are now too high. I'm going to try using the Leveller and see what effect that has.

Some further info:
When I try exporting to a WAV, the same thing happens, it's normalized to 0.0 dB.
I've experimented with the normalization settings. Going as low as -7.0 dB seems to produce an MP3 file where the variance between the original and the MP3 waveforms is visible.

I've been using Audacity for ten years and this is the first time I've encountered (noticed?) this problem. It came up because I'm re-mastering old podcast episodes for a new platform, which has a -2.2dB ceiling as a requirement for their audio files. I have tried this on two Windows 10 machines, my...
