Maestro Low Latency mixing (continued)

Figure A

To illustrate the eﬀect of latency, Figure A depicts the typical signal path of a vocal overdub session. A

vocalist sings into a microphone, which is routed to an analog to digital converter, then to the audio

software application for recording. In the software application, the vocalist’s live signal is mixed with

the playback of previously recorded tracks, routed to a digital to analog converter, and ﬁnally to the

vocalist’s headphones. A slight delay accumulates at each conversion stage, while a much greater

amount of delay occurs through the software application, resulting in the vocalist hearing his

performance in headphones delayed by several milliseconds.
