Interesting. Good to know. So if one were to snoop a gsm-encoded channel then attempt to record it to a gsm file, there would always be a gsm->sln->gsm transcode happening in there, correct?
Yes. The audiohook API turns it into signed linear and feeds it into a buffer that the snoop channel reads from at a specific interval.
The only time you could do a frame copy is if you are snooping on one direction. Otherwise you have to go to signed linear in order to mix both directions.
