Bad audio quality
I'm back with yet another question. ;-)
In my experiment the quality of the audio stimuli is really decisive. But the sound quality of my sampler items (voice recordings) is much worse when played in OpenSesame than when I open the same files in any other audio device on the system. They sound somewhat tinny with some noise added.
I run OpenSesame under Mac OS X and use the legacy backend, but expyriment gave the same results (while psycho always crashed before I even got to the stimulus generation). I played around with the sampler settings for legacy, but nothing changed. As it is the default, I think PyGame is used for the sampler although I don't know where it is specified. Is there any chance that audio quality improves under PyAudio? Or anything else I can do about it?
