    Audio Spectrum Analyzer








  

  

  





  Drop an audio file and see its acoustic spectrum!



> This project is heavily inspired by [spek](https://github.com/alexkay/spek)!

### What is this?

This is a small audio spectrum analyzer that I created after realizing that [spek](https://github.com/alexkay/spek) is no longer actively maintained.

I also wondered if it was possible to make it more performant and portable.

To achieve both performance and cross-platform compatibility, this has become a PWA and uses the browser's native audio API (which is fast!).

I'd say, pick any audio file and [try it out](https://spectrum.reinisch.io) :)
