"Much shorter than digital", but at what clock rate. It is my contention that digital systems at sufficiently high clock rates will be indistinguishable from analog systems.the analog audio systems have latency thats much shorter than digital. in "valve" audio systems, the electron transit time and actual time electrons have to flow is the latency, in digital systems, there is the a to d time, the delay thorough each chip, the processor cycle time, how much time the program takes to execute its program, and then the digital to analog delay time. in digital two way rsdio systems, if you get two radios to close together, when one is transmitting, you can heat the echo effect of the latency, like the old echo effects using a reel to reel tape recorder with seperate record and playback heads used to do.
Isn't that caused by packet transmission, repeating packets etc?current state of the art motorola radios have a definaly noticable latency.

I would qualify that to say 'indistinguishable' by the human ear. Jitter, quantization errors, and aliasing can be reduced to levels undetectable by the human ear."Much shorter than digital", but at what clock rate.

For mono signal source systems that's true if the signal chain effects all frequencies equally but most surround/multi-channel systems have time delay settings for each speaker or channel to comp for speaker distance analog delays because while we can't tell the absolute delay to range a sound we can easily detect delays on the same sound like a vocal from different directions from the right to left speakers. We normally would say the sound stage image is distorted when this happens and the voice seems to move in space rather that being stationary.Agreed! Human ears can do some impressive stuff.
But you can't "hear" the 45uS caused by the digital process, unless you are listening to the source sound and the digitally reproduced sound at the same time.
And if that's the case, the delay from the sound getting from speakers to your ears is 1mS per foot distance, so analogue delays from speakers->ears are massive compared to any delays caused by the digital processes.
And I would guess there are very few humans who can tell that one speaker is 12" further away from their ears than the other speaker, because they can detect the 1mS delay from the more distant speaker.
I can show the change in source sound image quality by only changing speaker delays on my cars 5.1 system. (poorly because of the limited range and channels of the video)And I would guess there are very few humans who can tell that one speaker is 12" further away from their ears than the other speaker,
