Linux Audio Interface Benchmarks

While many kinds of audio latency metrics exist, one useful and well-understood metric is round-trip latency; the time it takes for an audio signal to enter the input of a device, get processed, and exit the output.

The following measurements were taken using jack_iodelay.


USB Round-Trip Latency


Firewire Round-Trip Latency (FFADO)


PCIe Round-Trip Latency
