Dear list! Not having found any information on the website/forum/code: Anybody knows if it is possible to initialize PsychToolbox (WIN64) to playback sound with 24 bits on a suitable SC with an ASIO driver? Since it is PortAudio based, I guess this is doable? Any pointers towards code/docs/... would be appreciated. As I read it, 16bits is the default in PsychToolbox and there is not obvious paramater to change that (but I might be wrong). Thanks and a great day to everyone! BAstian |
