Basically you take a recording of a space’s acoustics and then the reverb characteristics of that space can then be applied to any audio signal. I usually use convolution reverbs for most of my music, since it’s a lot easier for me to use someone’s recorded impulse response of, say, the Ulm chapel than to fly to Germany to record there in person.

You can also use recordings of things other than acoustic spaces for interesting effects; Logic’s Space Designer comes with a whole bunch of impulse responses that are used for various effects, including drum transformers, ghost rhythms, and other such things. A lot of my more sound designy stuff makes heavy use of this.

But what if you use whole songs as an impulse response?

Here’s some results I got while messing around with it just now:

The way I did these in logic:

  1. Create an audio track with the source audio
  2. Add a Space Designer plugin, and drag the convolution audio onto it
  3. Set the “dry” level to Mute, and the “wet” level to 0
  4. Create an empty instrument track, and make an empty region that’s roughly the length of the convolution audio that starts at the end of your source audio (to give it a proper reverb tail)
  5. Apply the Mastering Assistant
  6. Bounce!

This seems like a really good framework for experimentation, especially for drone tones and ambient soundscapes. I’d be super interested to see what other people come up with!
