Goertzel filter / algorithm for Spectrum Analyzer

Open zz85 opened this issue 7 years ago • 0 comments

Continuing from #1

  • Tried https://github.com/Ravenstine/goertzeljs but its performance felt really bad, perhaps I had to do some down sampling.
  • Trying @notthetup https://github.com/notthetup/goertzel-filter implementation but lib requires some update to allow for multiple frequencies.

🚧 WIP...
