Drop an audio file and see its acoustic spectrum!
This project is heavily inspired by spek!
This is a small audio spectrum analyzer that I created after realizing that spek is no longer actively maintained.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 :)
