Problem in the sound of audio files presentation
I have experienced an apparent random problem when I present audio stim using Expyriment. Sometimes, the recorded sound comes along with some white noise. I am using wav files recorded using Audacity. I stress the problem is not related to specific files. For the same file, this problem sometimes happens, sometimes it doesn't. I have alternatively tried to convert the files to mp3 but then I ran into another problem: I get no sound at all even trying many different codecs, such as ffmpeg libmp3lame.
I am using Expyriment 0.7.0 (Revision 7a6b73d) with Python 2.7 in a linux machine using Ubuntu 16.04.
Thank you very much in advance.
