How to know the hardware buffer size

But no, of course this calculation is time-locked to the hardware buffer size (I/O buffer size) of the soundcard you happen to use. For a typical (low) setting, this is something like 128, so that would be 375 Hz (or a delay of a quarter second).

I’m afraid I don’t understand the question.

First off, 1 period / 375 periods per sec is 1/375 sec, not 1/4 sec. A 1/4 second delay needs 12000 samples at 48 kHz.

Then, the hardware buffer size affects the latency with which incoming control messages will be processed (unless they are timestamped). But if a UGen is controlling a hardware device, then it must be by way of the UGen’s output, which maintains full time resolution regardless of hardware buffer size.

Is there perhaps something else unstated about the scenario?
