REW + Reaper

[Lba]

Hello!

How could I combine the REW and Reaper programs?

I am working on a 16-speaker Ambisonic system where I do the finest calibration in distance to the center of the system in Reaper with the ICST plug in (Zurich University) placing the necessary delays on each speaker.
If I want to measure the frequency of the system with the REW, this distance calibration that I did will not be there.
How could I measure the system including that calibration?
Or how could I combine the programs to include that calibration?

What operating system do you use?
What is the output audio interface?

I'm using mac and the interface is a motu 16A

I can give you a general idea where to search.

Currently you have two signal chains
- Reaper -> eq/delay engine -> speakers
- Rew -> speakers.

You need to integrate rew into your signal chain.

I can see two possible solutions

1. Using reaper expose input channel for rew or use Jack for rew routing or use motu software to route rew signal. In this case signal change will be rew-> reaper -> eq/delay engine -> spekaers
2. Use system wide eq for your system
Signal chain
Rew -> eq/delay engine-> speakers
And
Reaper -> eq/delay engine-> speakers

Any suggestions are welcome. Post suggestions here. I will gather the details and add them. Thanks. :D This will be organized as results come in. @sweetchaos made a guide for PEQ filter data input and operation. For crossover software go here. Windows: AutoEQ four easy steps to make your...

You might take a look at the Hang Loose Convolver (HLC) from https://accuratesound.ca/hang-loose-convolver-hlc/

HLC can support up to 64 channels of digital I/O... You can put HLC on Reaper's FX Monitor...

Use REW's Generator function to create Sweep tone(s), with timing reference, saved to .wav file(s) that you then play thru Reaper... Measure your signal chain using REW and a mic... Make FIR filters for Room correction... Load them into the HLC...

Once you have your room correction then add your favorite EQ to the mix or on the FX Monitor... I like to keep room correction via HLC and any additional EQ, favor to taste, as separate items in the signal chain...

Rereading your OP I don't see any reason you can't just put the ICST plug in on FX Monitor...

Then use REW's Generator function to create Sweep tone(s), with timing reference, saved to .wav file(s)...

Play the Sweep tone(s) thru Reaper with ICST active... Measure your signal chain using REW and a mic...
