Description Martijn van Beurden 2014-03-10 11:25:42 UTC
Hi,

While I realize quite a few people here won't like it, but VLC seems unsuitable for general music playback, because it doesn't keep a stable pitch.

There's a nice ticket in de Videolan trac that sums it up: https://trac.videolan.org/vlc/ticket/10056

I've opened a thread on hydrogenaudio on this matter as well: http://www.hydrogenaudio.org/forums/index.php?showtopic=104958

Maybe it's a good idea to abandon the VLC backend and focus on something else?

Reproducible: Always

Steps to Reproduce:
1. Play music through the VLC Phonon backend
Actual Results:  
The first few seconds of the music are off-key, with pitch-difference as much as 1%. That's as much as 17 cent! After some time the pitch stabilizes, but for every new track the pitch drops again.

Expected Results:  
A stable, true pitch

This file was 'captures' by using pulse audio volume control to redirect the output to Audacity.
