If I convert an mp3 that is 128kbps to 320kbps than it looks like the mp3 is much better, No it isn't better. Encoding to MP3 always makes the sound quality worse because some of the audio information is discarded. MP3 is a "lossy" format, which means that encoding always loses some of th...

Which values? I don't see any values of +50, +150 anywhere on this page.
As I wrote previously, I am not a mind reader.

Click where you want to lock the cursor. Left-click-drag a small Quick-Play region anywhere in the Timeline Right-click over the Timeline and wait for the Quick-Play to stop. Choose "Lock Play Region" from the still open context menu. OK, so that's a bug, but I don't see a pressing need t...

Perhaps you could post a short example converted to 320 kbps with Audacity.

The waveform is hardly likely to "vanish" unless they also push the Threshold down to an extremely low level, but why does the threshold go so low anyway?

exporting it as MP3 compresses it again? Yes exporting as FLAC doesn't compress it? Correct. So, would it be better to convert a video online to FLAC first, open in Audacity for editing then export as MP3? The "damage" (loss of sound quality) is caused when the audio is encoded into a &qu...

Hang on. The very page you point to makes clear that the default (tied to the RMS choice) is downwards compression. Of course make-up to 0 dB is on by default. Yes, makeup gain is on by default, so the net effect is that it compresses "upward". As I wrote in an earlier post, upward compre...

Using the default sine oscillator: (defun note (pitch dur amp ) (scale-db (+ amp 2.99) (osc pitch dur))) (abs-env (seq (note c4 i lp) (note d4 i lpp) (note f4 i lpp) (note g4 i lppp) (note d4 q lmp))) The amplitudes clearly follow the defined dynamics: firsttrack000.png

(- amp 12 ) means amp - 12.
Whatever value "amp" is, (- amp 12) means 12 less.
So if amp = 18, then (- amp 12) is 6.

(scale-db (- amp 12 ) sound) will amplify "sound" by "amp - 12" dB.
