A free and open source WebAudio API loudness and masking analysis tool.

Made with some relic tech from the loudness war era.

Apparently loudness won.

Like this stuff? keep in touch with the contact box below! Get updates and feel free to share any ideas. I WILL build if idea's good!

P.S. current version has a little scaling bug with the graphs being displayed if you're using safari or a narrow screen, doesn't hurt much as you still get the vibe of what's going on, will fix in future updates.
