Title: Audio buffers in user-land audio driver
First up, many thanks to Jeff for the SampleHardwarePlugin example code. Like others on this list recently, I’m looking to create a device driver based on the example code. It’s making a lot of sense, but in trying to use it I think I’m missing something fairly fundamental about how the audio buffers are stored and passed around.
I’m not too familiar with IOProc operations, and I can’t see how I might access the contents of the output audio buffer in the WriteOutputData stage of the IO cycle defined in CallIOProcs. Is this the correct stage to be doing so, and if so, how would I retrieve the buffer? Apologies if this is a dumb question, but since the sample code obviously doesn’t do anything at this stage, I’m a little stumped.
All the best,
Dave.
