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?

$\begingroup$ i never listed code, but i have sorta illustrated an algorithm for pitch detection in a couple of different answers on this SE. $\endgroup$– robert bristow-johnsonDec 31, 2019 at 8:30

$\begingroup$ Hi Philipp, I'm sorry but asking for code written to a specification (here: pitch detection in the browser) is a bit off-topic here. General question: Doesn't Emscripten allow you to compile any C or C++ to WASM? $\endgroup$– Marcus MüllerDec 31, 2019 at 10:20

Try a samplerate of 48000 instead of 44100. Or vice versa.

$\begingroup$ This kinda solved the issue for me. Pitchfinder by default uses a sample rate 44.1k while Chrome records with 48k. $\endgroup$ Jan 7, 2020 at 8:44
