Reducing Latency in MainStage 3
Apple has published another nice support article yesterday, this time it’s about how to minimize audio latency in MainStage 3.
Audio latency is the phenomenon of sound reaching the ear at some point after it was created. In the natural world, latency is caused by physical distance from the sound source. The further away the sound source, the more latency. With digital audio there is also latency, and in this case it’s caused by buffering. MainStage (or any other audio software) needs some time to process audio data before it can be passed on to the Core Audio driver.
