Hi Guillaume,

Here's v2 and a log of me trying out the sbcl-cl-collider package in a sly REPL:

I'm not able to get sound. Would you like to test it yourself?

This is related: https://github.com/byulparan/cl-collider/issues/126

I'll give it another try soon once I find more time. The ecl package
fails. I opened an issue for it.

all best,

jgart
