Re: Latency issues (Re: Arch Wiki Professional_audio)

30 feet would be closer to 30ms, and is enough to make the feeling of playing the note and the sensation of hearing it start to feel disconnected. 

Try this stuff for yourself: take your synth or guitar or bass or what have you, plug it in to your computer, put a simple delay in the path with something like jack_rack, and play.  At some point it's going to start feeling weird.  Exactly where that point is depends on the person and the nature of the sounds you are making.

Here's another thing you can do: fire up hydrogen and make a pattern which is just a clave or cross stick playing quarter notes at a slow tempo.  send the output to both directly to your sound card as well as to an instance of jack rack with a short delay.  start increasing the delay time, by 30ms you will hear a clear flam.

Dear All,

while I'm not an audio professional, I found the (emotional) discussion on the
latencies quiet interesting.

That is exactly it. When playing bass, I find that once I am 30 feet away from the rest of the band

30 feet?, wouldn't that be on >80ms latency. If that's the order where 'disturbing' starts then
I find that number interesting, as (if I remember correctly) that's the fastest scale a human can react.

Which brings me to my questions. It might be  little bit of topic, but does someone know numbers on the
time it takes between wanting to pay a tune, playing it (e.g. on a bass) and the time it takes until one
realizes, that the tone is played? I think neurons switching time is of the order of 1 ms, so the physical
feedback can take pretty long. Signal velocity in nerves is also not too high. But brain might be cheating
in assuming having played. Is anything known concerning the latencies of a musician?

Best regards,
Peter
