Ok, one more silly question - how do I link either the FileStream, or the
channel to a specific file, etc.?
If I try initialising the FileStream object with what I think is sort of a call
to it's __init__ method, it seems to mention the following parameters, and
really not too sure what all of them should/would be - that's assuming need to
provide some of them since think this is an underlying part of the process
being mentioned in the trace back, or something:
bass_call(BASS_StreamCreateFile, mem, file, offset, length, flags)
As in, I would have assumed something like:
fs = sound_lib.stream.FileStream("file.mp3")
would have done it, but now not sure as such.
TIA
