Default ReaVerb, Valhalla, Waves, VoS 3D Ambisonic FX

After quite some trial and error with various techniques to arrive at a genuine Ambisonic B Format reverb using Valhalla reverbs, I finally put something together that works.

This track template can be used in Ambisonic mixes to achieve genuine, three dimensional, B Format reverb with width, height and depth input and output. If you solo the reverb, you'll hear all your directional and panning cues in the reverb mix.

I've used a bunch of channel mixing techniques, M/S decode and encode and level correcting JS plugins (all stock REAPER plugins) in combination with three instances of (in this first template), Valhalla Vintage Verb. Every parameter for adjusting the reverb is linked so all that is necessary is to adjust the first instance of VVV and the other two will follow. This includes selecting presets too.

The track template uses 16 audio channels. Channels 1-4 are the B Format input and output, channels 5-8 are X (front/back) reverb, channels 9-12 are Y (left/right) reverb and channels 13-16 are Z (up/down) reverb. EDIT - Those channel arrangements are for the older FuMa format. Blue Ripple Sound have just released their new SN3D updates which have the channel arrangements as WYZX. This is directly compatible with YouTube 360 and Facebook VR. These track templates will work with both arrangements without modification. Channels 5-16 are mixed internally in the track routing matrix and output back to 1-4. Those channels won't output to your mix so if you have other channels in the audio chain, it won't interfere with them. I am using this track template in third order Ambisonic mixes which have 16 channels of audio so I designed this template to work in that environment too.
Even though this template processes first order Ambisonics (channels WXYZ for FuMa or WYZX for SN3D), it is still very effective when used in higher order mixes. It isn't vital to have the reverb in higher order format to still be very effective.

All you need to do is send any B Format sends to channels 1-4 and the track will add reverb and output back to 1-4. If you are mixing in higher order Ambisonics, just send the first four channels to this track.

There's no reason you couldn't substitute any other stereo in/stereo out FX for the three instances of Valhalla Vintage Verb here to achieve genuine B Format FX. You'll need to set the channel i/o pins on each instance of your replacement FX the same way I have them set in the reverbs and you'll need to manually link each parameter from the second and third instance back to the first one if you want to have master control but it can be done reasonably easily.

I made up another one of these using VoS NastyDLA Mk2 and should have the track template uploaded over the next couple of days. As with the others, all knobs and controls are linked over the three instances for easy control.

The secret to getting a nice, wide spread is to use FX that have outputs that vary their calculations in such a way that no two instances produce an identical output.

Good grief Dave. Lots to learn from this. I know far too little and it's too cool for that.

Can you recommend a resource to learn about Ambisonics and how to use it ? I'm wondering how to monitor this effectively.

This sound amazing! Exactly what I'm after. I'm having trouble using it, though. I 'insert track from template' and nothing happens. I'm new to Reaper, am I missing something?

Thanks

Welcome aboard Vincent.

This track template works as an FX return channel. You'll need to send it a signal from your source channels and set up the send with multichannel source (four channels) assuming your sources are Ambisonic.
Are you familiar with setting up sends in REAPER yet?
I'm posting this from my phone so I can't post screen shots from REAPER.

Hi Dave, thanks!!

I'm familiar enough with tracks and sends etc. Watched 7 hours of tutorials.. :/

But when I say nothing happens I mean nothing. The track doesn't show up at all.




(In other matters, may I point your attention to another question I posed? Getting no responses as yet! https://forum.cockos.com/showthread.php?t=194834)

Great to hear you have it working.

I did read your question in your other post but my primary use for Ambisonics is for 3D music mixing rather than VR. As such, I haven't played about with cameras and object tracking so there's probably not a lot I could offer in that regard.
