Use ReplayGain to silence a mp3
For a wierd and obscure reason, I want to make an mp3 silent.  I have the mp3gain gui, but it doesnt seem to be doing it.  Hints or suggestions?

Well, I can tell you that a completely silent (empty) MP3 will be analyzed at 29 dB.  (I have no idea why, but I suspect it's an artifact of the ReplayGain algorithm).  Try setting your target dB to 29 or lower and see what happens.

Do you have an audio editor?    You should be able to create a silent audio file and save it as MP3.

I just tried this with Audacity:
Opened a file.
Edit -> Remove Audio -> Silence Audio.
Exported as MP3 (with a different file name).

Or with Audacity:
New
Generate -> Silence

Export

I think mp3gain tries to avoid doing 'bad things' like silencing mp3s so stops you overriding target volume too far.

Try mp3directcut instead and you can select all and apply contstant gain of at least -48 dB, and I think as low as -96dB, which is about enough, that's if you want to silence an existing mp3.
