Glitch at the begining of play

Sep 10, 2012 at 9:28 AM

I don't know if anyone noticed it. I tried to use a pure tone (Sine, 1kHz) mp3 file and analyzed the output using Sony SoundForge. What I found is that every time I call the MediaElement Play, there seems to be a sudden drop in the tone between 0.03 to 0.05 secs from the start of the file.

I tried disabling the audioPreProcessor, but the glitch stays. Is is something to do with the mp3 decoding??

Any ideas what's causing the glitch?
