I've left the Axe-Fx III on for a couple of days, with PianoTeq active on the background and after that initial overflow - it never occurs again and latency remains stable. What I've observed is when you first start USB streaming (in my case, I just open up PianoTeq stanalone app, which uses JUCE + ASIO in windows) - the output bar will slowly fill up over the course of 4-5 minutes eventually overflowing - the audio is then distorted, but eventually recovers (if it doesn't flicking the USB Buffer size parameter always recovers it) and after that point the output buffer level seems to remain stable. Note that Input/Output in that screen is from the perspective of the Axe-Fx - so When no activity is happening (no apps sending audio, etc) you'll see both bars at half without any movement.
#Usb audio loopback how to
Note you can see "USB streaming" activity if you look at Utilities->USB screen in the Axe-Fx III. In this video well look at how to use the LOOPBACK function of Universal Control and our PreSonus audio interface in order to record computer sounds (browse. Would it be possible to consistently get the lower latency number without resorting to keeping USB audio streaming always active? Live-stream and broadcast with ease using the innovative Loopback function.
#Usb audio loopback driver
So maybe something is reset in either the USB driver and/or the Axe-Fx III every time USB streaming stops/starts? Steinberg UR44C is a 6 x 4 USB 3.0 Audio Interface that features 4 Class-A D-PRE mic preamps supporting +48 V phantom power Details Additional Info Loopback function makes streaming easier than ever. Initial latency is around 352 samples, wait a few minutes, then it drops.
Wait anywhere from around 3-6 minutes - in fact just make it 10.From what I see in this video I can plug in my 3.5mm microphone and my 3.5mm headset into the desired inputs on this mixer and I will hear microphone loopback through my headset. Go to solution Solved by TheDiamondOreo, June 14, 2014. Leave RTL Utility open (so USB audio streaming continues) Need microphone loopback (without latency) By TheDiamondOreo.Measure the latency - I initially get in the neighborhood of 352 samples/7.23ms (again with the setup as described in the link above).Start RTL Utility - this starts USB Streaming immediately (you can confirm if you navigate to Setup->Utilities->USB tab.If already set to 8, make sure you toggle it to some other value and back to 8 to avoid the problem described in the link above Using the same setup as described in here, see if you can replicate this with the following test: I also ran into some other interesting behavior, where the USB Audio loopback latency drops after a few minutes after USB audio streaming starts.
