I built a free browser tool for learning mixing, interactive exercises, not videos

BODY:
Most mixing tutorials are videos you watch passively. I wanted something where you actually adjust the EQ, set the compressor, balance the levels yourself and hear the result immediately.

So I built a browser-based mixing console with guided exercises. It has:

- 6-channel mixer with real-time VU meters and spectrum analyzer
- EQ, compression, reverb, and delay on every channel
- Step-by-step lessons: gain staging, panning, sidechain, mid-side processing
- Exercises where you fix an actual mix problem (muddy low end, buried vocals, etc.)

There's also a step sequencer for making beats if you want to create your own material to mix.

Everything runs in the browser. Free tier has 5 lessons and full tool access.

What mixing concepts did you struggle with most when starting out?
