Audio Information
Number of audio ports (fixed) – 3: two USB Device ports for computer devices, one 4x4
analog port.
Number of buffered audio frames and Sync factor value: as with every device that
processes digital audio, audio goes into a buffer before it is processed, and it takes a
small fraction of a second for audio to fill the buffer as it streams through. This latency is
compensated for with the Sync factor value parameter so that incoming and outgoing
audio is in sync.
The larger the audio frame buffer, the longer this takes, but the lower the strain is on the
device; conversely, smaller buffers lower the processing latency and require more
computing horsepower.
The default settings offer low latency and solid audio performance. However, you may
wish to experiment with faster settings; or if you hear glitches, increase the buffer.
Audio Configuration – the sample rate and bit depth setting. This defaults to the CD-
standard 16-bit/44100Hz setting to ensure compatibility with all iOS software. Higher bit
and (to a lesser degree) sample rates can offer higher sound quality in some
applications, but they use more processing resources.
