The audience doesn't need instant feedback and low latency, the performers do. If you listen to a classic rock album, you're hearing the sounds with a "latency" decades after they've been played. But the playing is cohesive and tight. If one of the guitarists was consistently 50ms off, you would notice it. > Most Android apps have more than 100 ms of audio output latency, and more than 200 ms of round-trip (audio input to audio output) latency. It's also much more than just 10ms latency. I play with digital instruments all the time, the latency can be as high as 15ms before I can tell. I don't know if an audience can perceive a 15ms latency, especially because you tend to "play early" to have notes land on time. But it's very upsetting for performing. I haven't tried playing with music apps on Android recently, but when I did, the latency was not just long, but inconsistent, and would result in stuttering in the audio.
