I'm still using the old 0.9.9 version because that's the last version that has the old Slow Motion = Deep Pitch sound effect when you slow down the music. I actually like my music to sound deeper when I slow it down. So I've refused to upgrade for years.
I did need to restart VLC for that to take effect. This is VLC 1.x (whatever the latest in the Ubuntu repos is). I suspect the option is still available in VLC 2.
Not only there is an option to deactivate this, but VLC 2.0 gives you better resampling quality and does not cut audio files in the beginning and the end.
