Audacity is run in pass through mode with internal latency set to 0.
I would like to measure the round trip latency from jack_system (in) to
jack_system (out)
Easy using jack_delay.
1. Measure the round-trip latency of your sound card (with an
external analog loop).
2. Measure
jack_delay -> pa_source -> audacity -> pa_sink -> jack_delay.
3. If pa_source and pa_sink are a single Jack client (probably not),
subtract one period from the result of (2).
4. Add the two values.
