USB audio data is sent once per frame over the bus (1 frame = 1ms), and the driver prepares the data for four frames in advance, so the latency would be at least 5ms, not counting any delays in the software or in the device. It may be possible to lower the latency by changing the definition of NRPACKS in usbaudio.c, but it will never be lower than 2ms. > Something like the above mentioned Edirol would be great, if the linux > support is good and it works for life realtime processing. Nearly all USB audio devices are supported by Linux. See <http://www.qbik.ch/> for a device database.
