Audio delay. This term typically refers to the delay introduced by PC and Mac soundcards becuase these use buffers at a certain size to receive and output sound data. The longer these buffers are, the longer the delay before the generated audio is sent to the loudspeakers. This delay is called "latency" in audio terminology.

The latency can be calculated by dividing the length of the buffer in samples by the samplerate. A buffer of 256 samples at 96000 Hz samplerate would then be 256/96000 = 0.00267 seconds or 2.67 ms.
