Has anyone found a good multichannel method for sub-millisecond delay? Not in a DAW!
In my case I need to take six analog channels in and spit them back out as analog a very short time later (ideally balanced on both ends), as a lookahead solution for the main audio heading into gates, when using the non-delayed signals into the keys to trigger. The best I can come up with is a simple ADC / DAC, free-running, with at least a couple of sample rate options (the RME ADI-8 DS comes to mind, as does the Apogee Rosetta 800). But maybe there’s an analog solution, or a prebuilt converter board that I could put two of in a box with a rotary switch and two DB-25s? (Yeah I know the Rane G4 has lookahead. Committed to analog gates because they’re already here.)
There are simple products marketed as “audio delays” for the broadcast industry, notably from RDL and Kramer, where you get millisecond steps above their normal onboard roundtrip latency, but you only get one option below 1ms. There are laboratory microsecond delays too, but very pricey and always mono. There are of course DSP mixers, but they all start around 1.5ms round trip.
