thanks for sharing! what’s considered the lower bound for comfortable latency?

• danbmil99 6y ago
  In audio a delay of about 5 milliseconds is the most you can comfortably accept without it seeming really annoying. Well-designed, expensive hearing aids have extremely low latency, but there are theoretical limit. The more frequency domain processing you want to do, the more samples you need to do it, and the more delay you're going to have even in the best-case engineering. Smartphones are unfortunately typically not able to meet these kind of specifications. Much longer delays are acceptable in voice communication because you don't hear your own voice and the delayed voice at the same time. Point being, it really has to be a specialized device designed from the ground up to keep the latency close to the theoretical low limit.
