Dear cafe and Dr. Henning Thielemann, I'd like to propose a new package named simple-dsp. I couldn't figure out how to use the existing dsp library, so I made my own version featuring a little GUI to try the code in realtime. I'd be happy to contribute this work directly to dsp. My goal is to be able to extract sensible discrete values from a sound input at 60 Hz for video production. I implemented low/band/high pass filters to compute 3 RMS volumes, but the values I'm getting are not sharp enough, e.g. the band pass picks the low end. Ideally I would extract the transient events of the percusive sound and the note pitch of the melodic elements. I have very little understanding of DSP, and I'm sure there are better ways to achieve this goal, so I would appreciate it if someone more experienced could take a look: * Doc: https://tristancacqueray.github.io/simple-dsp/ * Candidate: https://hackage.haskell.org/package/simple-dsp-0.1/candidate * Forum: https://discourse.haskell.org/t/rfc-a-new-simple-dsp-library/9094 Thanks in advance, -Tristan
