Some math [1]
44.1k file containing pulses with sub-sample delays [2]
Something similar, but square wave, and nicely showing that timing precision actually depends on bit-depth and not the sampling rate [3]
Some practical experiments with capturing the playback of such files and verifying that the delay is preserved: pulse [4] and square [5]
