Config volume and speed for each song

[theeasternfurry]

Describe what you want

Some of my songs that are play as instruments and need to increase volume, while some of them are cool when speed up or slow down. Currently termusic increase or decrease speed and volume are global and apply all of song.

Do you have already an idea for the implementation?

Well, have a global config to enable volume & speed for each song may seem a good idea.

So you practically want ReplayGain?

The suggestion already exists in the discussion at #284.

Yeah, ReplayGain looks okay, but I also like to have playback speed/tempo options for each file. Can we do that? I mean, it could save a little extra space, even though I can easily output the song as another file after modifying it.

[hasezoey]

As speed is definitely not part of replaygain, i guess we could do that as another column (or maybe even table?) in the database.
Though seeing as this should likely also be possible for podcasts, that database would need to be modified as well.

As for UI decision, should this just be a shortcut, or should we finally introduce a "context" menu on a track (in the playlist / filebrowser / database browser)?

[theeasternfurry]

Storing it as a new column in the database makes sense since it's separate from ReplayGain. And I think introducing a proper context menu is definitely the way to go for the UI—it'll be much cleaner than adding random shortcuts everywhere.
