Latency and samplerate

rymdprojekt · Mar 4, 2006, 05:15 PM

Why does the latency decreases when i use a higher samplerate in the asio panel?

I have seen this in other programs as well...

is there anyone who can in a simple way explain this?

thanks

The latency calculation is:
Latency = 1000 * BufferSizeInSamples / SampleRate

If you just plug in some numbers the results speak for themselves.

i.e.
1000 * 256 sample buffer / 48000 sample rate = 5.333 ms
1000 * 256 sample buffer / 44000 sample rate = 5.818 ms

Figure that with higher sample rates, the buffer is filled faster, so it takes less time (buffer size divided by the sample rate, is the difference in the calculation).
