Pitch Detection in the Browser Does anybody know a good library that does pitch detection in the browser? Anything in Javascript or Webassembly would suffice. My target is mainly singing voices. I already tried pitchfinder, but for me it reports frequencies that are a half tone to low. Are there any alternatives other than implementing an alorithm your self?
Try a samplerate of 48000 instead of 44100.  Or vice versa.
