Honoring the original samplerate in mp3 [not relevant]
While testing the audioplayer in Jolla I had two files with the same origin: - wav with sampling rate of 44.1 kHz - mp3 with sampling rate of 44.1 kHz
The player showed different playing times and it seems to me that it wanted to play the mp3 with 48 kHz sampling rate. This is annoying and here comes the link to the real situation with wrong sampling rate :) http://warmowski.wordpress.com/2007/10/05/jump-in-pitch/
