Synchronisation in multimedia involves two concepts which are often confused: <strong>clock</strong> (or speed) and <strong>time</strong> (location in time).

To achieve sample accurate timecode synchronization, the latency introduced by the audio-setup needs to be known and compensated for.

Linux DSP guru Fons Adriaensen wrote a tool called <code>jack_delay</code> to accurately measure the roundtrip latency of a closed loop audio chain, with sub-sample accuracy. JACK itself includes a variant of this called <code>jack_iodelay</code>.
