Possible to add sox support (for mp3) [Request]

[l3uddz]

Hi,

Was wondering whether you guys would beable to add the ability to remove "silence" from the downloaded mp3 file as a flag? so we can get rid of the annoying few seconds of silence at the end that accompanies most youtube video mp3's?
This can be achieved using a tool called sox with a command like
sox "music\Shaggy - Intoxication\6 - Woman Scorn.mp3" "music\Shaggy - Intoxication\6 - Woman Scorn.mp3" reverse silence 1 0.1 0.1% reverse ... Would be nice if you could add it as a flag and youtube-dl will do itself

I know this is an old issue, but I ran across a Spotify downloader that uses youtube-dl as a backend (i.e: it actually only gets metadata from Spotify and downloads an equivalent on youtube) that has this feature. This could be a good starting point:

I saw this argument somewhere on the web, but I haven't tested it yet.
mp3splt -r *.mp3
