Ultra-low I2S audio latency on ARM

The I2S format used in the circuit board of your vintage CD player is proving very interesting as a peripheral interface for full-duplex, multi-channel audio boards on ARM devices. At the request of the openMHA community we have developed a hearing aid research distribution codenamed 'Mahalia' for the BeagleBone Black, with the lowest audio latency figures we've seen on any GNU/Linux device. Please see our presentation at Embedded Linux Conference Europe below, and the openMHA presentation video from the Linux Audio Conference for the details.
