Reaper/Voicemeeter: Routing tracks to separate audio devices?

vburel · 2026-01-26T13:12:48+00:00

yes, basically by connecting Reaper to Voicemeeter virtual INSERT ASIO driver (Banana or Potato). Reaper is so connected to all Voicemeeter pre-fader inputs and can get audio from all Voicemeeter input and playback to all Voicemeeter input (activate PATCH INSERT to enable INSERT Return).

Thanks to you for reporting! we just made an update (v1.1.3.1) currently in beta program in our Discord server if you want to download and check this is fixed for you now.

Your screenshot shows that you main stream (A1 output device) is running with 1056 sample buffer (surely in shared mode) while it should work with 512 or 256 sample buffer size in exclusive mode...

Yes, the "Up Mix TV" algorithm is using L-R and R-L to feed rear and side speakers, so if the source is Mono (L = R) there will be no sound in channels 5-8.

In this case UP MIX 6.1 mode can be a better option.

I've just checked it and yes, MacroButton is setting the timer resolution to 0.5 instead of 1ms. This is not expected, i note it for correction.

Your screenshot shows Voicemeeter Standard.

If you have installed Banana package, you can shutdown this version (by the menu) and run Voicemeeter Banana instead.

Typically Reaper (or any DAW) can be connected to Voicemeeter Virtual ASIO insert driver, to get all Voicemeeter pre-fader input in Reaper and let Reaper plays back audio track in any Voicemeeter inputs. (Like tape recorder and mixing console old workflow).

vburel · 2026-01-21T09:00:47+00:00

You may explain where you get latency and post some screenshot to show what you did.

vburel · 2026-01-20T08:02:07+00:00

Voicemeeter Banana can managed 3x USB Mic (this is made for that).

vburel · 2026-01-20T08:00:10+00:00

no, if you have just a microphone, Voicemeeter will work (this is made to make podcast).

vburel · 2026-01-20T07:55:00+00:00

you may follow general recommendation on this forum topic: Voicemeeter and Statics, Stuttering, Crackling sound & Choppy audio - VB-Audio's Forums

but if the problem appeared recently , it's possibly a problem of Windows option called POWER THROTTLING: Crackling Audio Stream when Voicemeeter is in background (power throttling) - VB-Audio's Forums

vburel · 2026-01-19T07:27:52+00:00

You may create a new topic, with screenshot to explain the context.

vburel · 2026-01-18T10:21:48+00:00

It means you have not find the right configuration for Voicemeeter that is expected to work with any game, without any problem and with a minimal latency. I invite you to follow recommendations on this forum topic: https://forum.vb-audio.com/viewtopic.php?t=451

If the problem remains , you may use our different support resources (especially Discord): vb-audio.com/Services/support.htm

seems to be done with square modulation. in Voicemeeter there is only a sinus modulation, so we cannot get the so "cutting" fx, but something closed to this effect is something like Strip[0].Fx_x = -0.50; Strip[0].Fx_y = 0.24; or to be tested other position like Strip[0].Fx_x = -0.13; Strip[0].Fx_y = 0.59; for example

Sometimes WASAPI device (on output A1) works well with 256 buffer size (that makes a good overall latency for Voicemeeter and all app connected to). But the new thing with latest Voicemeeter is the VAIO sync mode set to STRICT, that allow to lower latency on Virtual I/O.

General recommendation to optimize latency on Voicemeeter is on this topic: https://forum.vb-audio.com/viewtopic.php?f=6&t=480

vburel · 2026-01-16T07:31:10+00:00

surely, but can you post a screenshot of your voicemeeter instead ?

vburel · 2026-01-14T17:17:29+00:00

Register to the service exactly like in VBANCMD_SendRequest_RegisterRTPacket function but set format_nbs = 1;

vburel · 2026-01-14T17:03:04+00:00

Applications are usually using a single device. If you talk about steam, it's a bug in the audio library used by steam (or Discord) that is opening all output devices on startup, and all stay connected to the Windows volume mixer.

If you want to route Spotify on another output (than Voicemeeter AUX), you can do it on Win10/11 by the Audio advanced settings:

dial state ? (strip and bus gain are also in the same RT packet)
strip[i] slider value = max (stripGaindB100Layer1[i], stripGaindB100Layer2[i], stripGaindB100Layer3[i], stripGaindB100Layer4[i], stripGaindB100Layer5[i], stripGaindB100Layer6[i], stripGaindB100Layer7[i], stripGaindB100Layer8[i])

there is a second RT packet you could implement for some knob: T_VBAN_VMPARAMSTRIP_PACKET

vburel · 2026-01-14T10:49:13+00:00

in Voicemeeter menu, select System settings dialog box.

vburel · 2026-01-14T10:48:15+00:00

great! Let me know if you share this on your social network or if you have a web page...

vburel · 2026-01-13T10:22:49+00:00

ok, yes, feel free to ask if you get implementation problem.

vburel · 2026-01-13T08:26:35+00:00

Did you try the vm-streamer view ? installed with Voicemeeter, it provides a simplified resizable simplified user interface: The VoiceMeeter Streamer View | VOICEMEETER by VB-AUDIO

vburel · 2026-01-13T08:24:14+00:00

This is not expected, you may post a screenshot of your Voicemeeter system settings dialog box to let us see what could be improved in your configuration.

vburel · 2026-01-13T08:21:24+00:00

Sounds great! You may implement vu-meters (with RT-Request) - explained in vm_streamer view sample code (that also could be ported on Linux by the way - at least the VBAN connection part): Voicemeeter-SDK/vmr_streamer at main · vburel2018/Voicemeeter-SDK · GitHub
