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.
