PortAudio returns default latency values that applications may use to configure audio buffering without further user intervention. These values are expected to provide both stable audio (no glitches) and provide the lowest feasible latency.

Many native APIs do not provide adequate guidance as to how buffer sizes should be dimensioned. We could perform a survey of many machines to better determine workable defaults.

Some tests have already been written. See tickets #185, #186 however, at this time we have not committed to running them on a large number of machines as would be required to have a high confidence our values are good.

Could possibly use a loopback automated test instead of the manual test procedure.

This ticket is about conducting a large scale test (perhaps crowdsourcing many novice users with a highly usable UI).
