hmm.. syncing the files is actually one thing im after. Right now i just compare the times and seek on the filestream if a certain threshold is passed.
but the thing is, when I play a mono file without a mixer, both channel 1 & 2 are used. Or at least I havent found out, how to occupy only one channel. Also, AudioOut (Bass) only recognizes the channels stereo/pair-wise. At least with my audiocard HDSP AES-32 which has 16 channels.
So working with the mixer lets me address every single channel on my audio device and I can start and stop all myFileStream (Bass) nodes.
By the way, I found out that the Audio apparently starts with on time, but the time which FileStream (Bass) delivers, is wrong.
still working on it.
