number of audio channels, and bit rate. (Audio channels are divided
evenly between input and output.)
The higher each of these numbers is, the more data is transferred
and therefore more bandwidth is used. Under some but not all
conditions the audio quality may improve slightly at 24 bits rather than
16, and extremely subtly at 96kHz vs. 44.1 or 48kHz, so there’s a
very small trade-off between performance and sound.
Modern computer devices are fully capable of glitch-free performance
at any of the seven settings. However, every computer has finite
processing resources, and power-hungry software can put a strain on
any system,
Number of audio frames to buffer
and
Sync factor value:
as with
every device that processes digital audio, audio goes into a buffer
before it is processed (in the iConnectMIDI
4+
,
for routing), 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 setting of 2 audio frames offers low latency and solid
audio performance. However, you may wish to experiment with faster
settings; if you hear glitches, increase the buffer.
Port Information
The Port Name here is editable, and the Number of Input/Output
channels fields reflect the settings in the Audio Configuration field
above. Note that you can enable or disable each port.
