Maestro Low Latency mixing (continued)
Figure B
By routing the hardware input directly to the hardware output and mixing in playback as shown in Figure B,
it’s possible to provide the vocalist a headphone monitoring signal with a much shorter delay.
First, the signal being recorded (in this case, a vocal mic) is split just after the A/D stage and routed to both the
software application for recording and directly back to the hardware outputs without going through the latency-
inducing software. This creates a low latency path from mic to headphones. Next, a stereo mix of playback tracks is
routed to the low latency mixer and combined with the hardware input(s). This allows the performer to hear himself
while listening to playback tracks without a confusing delay in order to comfortably record overdubs.
Note that the software application’s mixer is used to set a stereo mix of playback tracks while the low latency mixer is
used to set the balance between the stereo playback mix and the hardware inputs.
Setting Sample Rate
Duet operates at all standard sample rates between 44.1 kHz and 192 kHz. In most cases, the sample rate
is set by the audio application with which Duet is communicating. For example, when using Duet with
GarageBand, Duet’s sample rate is automatically set to 44.1 kHz, to match the GarageBand song’s sample
rate. For those audio applications that don’t include a sample rate setting, such as iTunes, Duet’s sample
rate may be set in Audio MIDI Setup or on the System Setup tab of Maestro.
