It kind of is possible to "profile" a reverb

I've had this in my 'interesting links' menu for a while.

I don't fully understand it yet. But in essence it looks like it is a neural network based approach to clone a reverb.

I've not tried it yet, but they provide models if you'd like to check it out. But what I'm interested in doing is obviously capturing the living doo-doo out of my favourite reverb algorithms.


@FractalAudio @Digital Igloo - be interested to know what you think of this!

For everyone else, there is a VST2 in the repository. You can load their provided models into it, it looks like.

It actually sounds really nice.

I was thinking about something "similar" (?). Since the QC can capture cabs... wouldn´t that mean you can capture acoustic guitars with a mic? Just in the same way that acoustic guitar IRs are made, or reverb IRs... which leads me to your reverb capturing subject. Maybe I´m completely clueless about it, though.

I´m curious too.

Not quite. It's basically using AI to synthesize IRs for convolution reverbs, based on some ~1500 samples for training.

The proof of concept is a bit limited, but otherwise quite impressive. It can f.ex. move the "microphone" in 3D space.

Right... but imagine you had a ton of IR's of a particular reverb ... train the model with it .... reduce the 3D space to one dimension, and you've just cloned a reverb at its current settings, and given the user control over the decay.

That's my thinking.

We uploaded a tutorial on YouTube showing how to capture reverbs as convolution reverb IRs :)

In addition to the NAM player (up to 60-second), the Strymon BigSky MX also supports long reverb IRs of up to 10 seconds.
