Topic: Latency in Logic Pro X on macOS with the ADI-2 Pro FS R Black Edition

Hi, can anyone tell me the latency in Logic Pro X on macOS at 44.1 kHz with 64 buffers for the ADI-2 Pro FS R Black Edition?
This would be very helpful.

you can easily measure that in logic pro x. put the device into loopback mode, simply create a pulse, play and record at the same time, and measure the roundtrip latency.

That might not give the expected results.
The automatic latency compensation places the recording at the source position.

I don't own the ADI-2 Pro FS R Black Edition, hence my question.

The ADI-2 itself doesn‘t introduce any significant latency, aside from a few samples that the DSP and DAC-chips need for processing.
Manual page 75 gives the figures.

The numbers at the bottom of the page are RTL, Round-Trip-Latencies ADC-computer-DAC, for DAC only cut them into half.


• For DAC / computer playback at 96 kHz, expect something around 1 ms.


Here‘s a table of the pure ASIO buffer related latencies (one direction, not RTL) vs. ASIO buffer size.
At higher sample rates the latency further diminishes proportionally.

Thank you very much. Unfortunately, these numbers rarely add up in the real world, and each DAW handles these numbers differently (e.g. Ableton Live usually has lower numbers than other DAWs for the same drivers and/or plug-ins that introduce latency). Here's the ADI-2 Pro FS R Black Edition, as you can see it's as good as the AudioFuse in this respect and worse than the average Thunderbolt interface (strictly speaking for output latency):

Maybe he can turn off the latency compensation
