And in the usb modes used by audio interfaces, there are protocol considerations that contribute to the practical latency lower bound, such as the framing of data in URBs and scheduling them on the millisecond rather than sending data as soon as it is available during each polling period.The Behringer X32 instantly became a milestone among mid-priced digital mixing consoles when it first appeared, and it has lost none of its appeal since then. It's definitely not true that USB-3 "is capable of (much) lower latencies" than USB-2 for audio delivery. As you note, this finding is completely irrelevant to audio interface latency, though. it is possible to transmit a single packet with a very short round trip time. For at least one specific combination of protocol-mode, chipset, on an RT kernel that can't run desktop software, and possibly on a custom/toy driver. This is a phenomenally confusing way to kick off a discussion in an audio forum about the abstract theoretical limits of USB round trip times in non-audio applications. This is not relevant because the Behringer x32 only does USB 2.0, but I'm pretty sure USB 3 is capable of (much) lower latencies. There are many other ways to approach your monitoring, but can definitely flexibly switch between direct and through the box monitoring. which can either be the short post-fader path in the X32 or all the way through the DAW and back into the X32 via USB returns channels. In both cases, the audio goes out over USB and gets recorded to disk, it's just a question of what route does it continue on to get to the bus that drives the phones/monitors. Or obviously you could unmute both and get phasey-garbagey duplication.Or mute the track in the DAW and unmute in the X32 to get zero-latency monitoring.Mute the track in the X32 and unmute the track in my DAW to monitor through the DAW output returning back into the mixer.In my simple little setup, I have my usb-outputs configured to be pre-fader in the X32, so I can either: DBB audio has some good videos to help orient yourself, but the flexibility of a full matrix desk mixer is a lot of you're not used to it. If you have to ask this question, you may actually find yourself overwhelmed at first by the matrix routing functions (I was). Yeah you can setup whatever routing you want. If you want to know for sure, you can measure it with jack-iodelay. You probably have 2.7ms of buffer latency plus some other hardware latency amounting to 8-10ms of total round-trip latency. I don't believe there exists a USB audio interface that is capable of delivering that round-trip latency, I believe the USB protocol/bus itself is only just barely capable of that round-trip if the HW/SW have a latency budget of zero. I have an X32-Rack, which does have a small screen and knob-UI, but it's not real pleasant tomuse through the hardware controls so I generally use the software and it doesn't drive me crazy.Įdit: As an aside, you almost certainly don't have 2.7ms of round-trip latency over USB. I find it fine for live synth and liveFX though. From memory, I think it's 12-15ms as measured by jack-iodelay. Round-trip latency is good but not great.I mainly use the on-boards stuff for live work (lower latency, and less worry about crashing software) and plugins for multi-track (because it's convenient to experiment in the DAW). On-board fx work, and mostly sound decent.The routing is super-flexible compared to the low-end analogue mixers and small track count audio interfaces I previously has experience with.There is no 96khz mode if that's important to you.I never measured that, though I just configured for 16-track I/O because I didn't need the extra capacity. I don't need the extra 16 tracks and I sort of imagined maybe latency might be better or more consistent if I turned them off. I usually run it 16ix16o over the X-usb card at. but occasionally with a variety of other mostly jack-based software as well. I use my X32 as my main multi-track interface, through jack and ardour mostly.
