Yup, not sure where the OP got the 5mSec number; perhaps it's about the soundcard buffering but then it's probably sort of high end using ASIO drivers and a rat

Yup, not sure where the OP got the 5mSec number; perhaps it's about the soundcard buffering but then it's probably sort of high end using ASIO drivers and a rather small buffersize (say 192 samples at 44.1kHz) because I duoubt your everyday buit-in soundcard achieves that. But it cannot be about the speed of the analog signal from the DAC until it reaches your speaker: too lazy too look it up but worst case IIRC is still half the speed of light so not even near mSec range.
- jefftk 6y ago5 milliseconds is about what you'll measure for latency if you measure a wired headset, but yes, you're really measuring your sound card.

- oxfeed65261 6y agoTyvm, this is super handy! More precisely, ~1.01670 ns/ft (~0.983571 ft/ns).
- iso1210 6y ago1ns = 300mm (or 30cm) 1us = 300m 1ms = 300km

- leephillips 6y agoThe signal speed has nothing to do with the electrons’ drift velocity. It is a bit slower than c, but negligibly so.
