We have very strong requirements regarding the maximum latency from audio input via line in to audio output. We would like to achieve a maximum latency < 1ms. The alsaloop example mentions a latency of 1 ms which is on our test setup
What hardware? USB and FireWire have long packet queues.
We tried different soundcards and found out that they have an internal FIFO, which seems to be one of the limiting factors.
What are the numbers?
What settings did you use for alsaloop?
