[Alsa-devel] Understanding JACK's inner loop?

[Ryan Cassidy]

Hello all,   I am trying to understand the specifics of the mechanism that JACK uses to perform audio duplexing (simultaneous playback and capture of audio).  I have downloaded the latest source from CVS.  Is the file ‘alsa_driver.c’ a good place to start (i.e. is this where the magic happens)?  Does JACK use memory-mapped read/write?   Any info. greatly appreciated.   Cheers, rjc. -- Ryan Cassidy Electrical Engineering Graduate Student, CCRMA Researcher Stanford University E-mail: [EMAIL PROTECTED]
