      Does anybody know if the envelope follower node is working on a linear or dB domain?

      It seems to me at first that it is linear, but when I am adapting the signal to be decibel normalised, then the attack/release timing is messed up (like needing to set it to 10sec to be usable...)

      The code source shows a log transformation but it seems to be used only by the updown_compressor node (which is derived from the EnvFollower), as I don't see this logarithm part in action for a pure envelope_follower, but of course that could just be me being blind

        @ustk linear, like all modulation in scriptnode:

        but the time response is exponential.

          @Christoph-Hart Yes of course for the mod output, but I was more talking about the signal detection. Once working on the dB scale it can still be normalised at the output. But I get it now, I have what I needed thanks 👍

            signal detection = mod output (minus smoothing), so still not clear what's the problem, but glad you solved it :)
