Hey, new user here. Issue is pretty straightforward:
Latency is being over-corrected by ~6 ms.
Ardour seems lovely and a good fit for me, but this is a deal-killer if I can’t solve.
Mac mini, 64 bit Ardour 5.12.0, Behringer umc404hd interface over usb.
At startup, run the ‘Calibrate Audio’ button. Very consistent readings of:
detected roundtrip latency: 2274 samples
systemic latency: -59 samples
(at 48k sampling rate)
Three user settings which appear to have no actual effect:
Hardware input latency
Hardware output latency
(both fields in the startup dialog)
Adjust Latency in the individual track pop-up menu
So by trial and error I have found that those settings have no effect, and new tracks are consistently recorded ~6ms ahead of existing tracks.
Thanks for any help!
