Default Re: MTRX Studio Mic In's / Dolby Audio Bridge...


Have you been able to test this again with the latest 2022.12?

I upgraded my Mac Studio to Ventura 13.1

I'm getting much better results.
Both with Rosetta and Native.

Though testing in native is limited due to compatible plug-ins
i.e.(Nugen Halo 3D, Elixir, Dolby LTC, Stratus 3D, FabFilter)

I have managed to measure DAB + PTAB at 1024 sample buffers with a loopback as low as 79ms, and as high as 119ms. At 32 sample buffers I have managed a loopback as low as 59ms and as high as 71ms. That probably accounts for the rubbery sync some people are experiencing.

Even weirder, when using HDN as usual to feed the renderer (no aux I/O, just Pro Tools -> Digilink -> Madi -> Renderer -> Madi -> Digilink -> Pro Tools), the sample buffer setting has zero impact on the loopback results. Regardless of whether Pro Tools is set to 32, 64, 256 or 1024, the latency is always a fixed 2702 samples/56.3ms.

Something is busted, I reckon.
