Using Reaper as virtual mixer for live streaming (Mac/OBS/Facebook Live)
Hi all,
I'm basically a Reaper newbie, recorded a couple of dozen songs using the DAW. I've run a couple of guitar/vocal Facebook Live streams using the following basic setup for audio (and a DSLR for video): Zoom H5 as audio interface (built-in stereo condensers and/or 2 connected mics) into a MacBook running Mojave.This limits control of my audio to basically the gain dials on the Zoom H5. The signal going into OBS is already merged into a single track, so no control there either. I also have a Focusrite Saffire Pro 14 which is my main audio interface. I was just experimenting with the H5 because it's a simpler quicker setup but either will work. The Focusrite certainly has better pres and I've got an LA-610 hooked up to it I can use on the vocal. What I need is a basic mixer for EQ, panning, compression, and reverb. I was thinking about an inexpensive USB Mixer interface for simplicity. A huge shout-out to Alto Music who I called today asking for recommendations. After hearing the info above, they essentially turned down a sale and said I'd be better off running through my DAW as a virtual mixer. That's great customer service. I'd considered this. I have BlackHole (Soundflower replacement) installed and have set up an aggregate device. I watched a couple of Kenny's videos on routing so I kinda get the idea. I could probably trial and error this and get it to work, but any pointers for proper routing/settings setup would be helpful. Better, for instance, to set up a buss track to send to OBS instead of the master mix? One thing where I suspect I might get hung up: a way to monitor the mix (with eq, comp, reverb, etc) with low enough latency while I'm streaming myself singing/playing? Or am I better off with the dry monitoring of the inputs straight off the audio interface? I did see where Kenny showed how to setup up a buss track for a headphone mix, for instance. I'd like to come up with a simple setup that I can just go to whenever I want to go live. Thanks! Last edited by BerkeleyBernie; 04-02-2020 at 07:55 PM. |

Just try it. It should work. -Michael |

Reaper is perfect for a live mixer before OBS, I use this setup myself for live streaming. signal flow for audio would be: soundcard to Reaper to OBS Reaper to Headphone Out so you have 2 outputs from reaper the one to OBS you aren't as concerned about the latency, but the headphone out needs to be low latency so your sound card drivers need to be set so you can monitor in realtime 128 buffer should work. Treat reaper like a normal audio mixer with FX and aux out. also you can record yourself in reaper and playback to tweak your live mix before you go live. OBS has video and audio delay filters. once you have audio and video arriving in OBS, you will need to make sure that you still have lipsync by adjusting either the audio or video delay to match up. from experience... use the OBS record feature to watch the resulted video in something like VLC. OBS seems to put out audio late if monitoring from within the program. there are many ways to get audio from reaper to OBS. I use rme interfaces and they have a loopback feature for that. but blackhole which you mentioned looks like it would also work especially since the audio loopback can be a little delayed and resynced in OBS |

Thanks for the info.

I was looking at the Presonus Studio 192 today. If I get serious about this, I might upgrade my interface. The advantage there (or perhaps some similar hardware) is it has a DSP chip that handles a channel strip and reverb/delay effects outboard as well as a mixer, so can bypass Reaper (or Studio 1) altogether. Then just do a stereo send directly to OBS. Quote:
