About
A Small Set of Audio Tools
This site exists to answer specific mixing questions in the browser, without an install, an account or an upload.
What Is Here
Five tools, each built around one job: reading a file's spectrum and level, correcting its balance with an equaliser, controlling its dynamics, finding where two parts collide, and programming a short pattern. The equaliser also contains a blind trainer, because the useful skill is not moving a fader but knowing which frequency to move.
How It Is Built
Everything is static HTML, CSS and JavaScript. Audio is handled with the Web Audio API, with no audio library and no back end: the site is served from a CDN and every calculation happens in the tab.
The demo loops are generated with an offline audio context when you press the button. No samples are shipped, which keeps the pages small and avoids licensing questions entirely.
What It Deliberately Does Not Do
- It does not upload, store or transmit your audio.
- It does not ask for an account, an email address or a payment.
- It does not auto-play sound, or pretend to be working when it is not.
- It does not claim that a suggested cut will fix a mix. It suggests starting points.
Accuracy
The analysis is real arithmetic on the decoded samples: peak, RMS, crest factor, band energy, spectral centroid and a least-squares tilt. The suggested corrections are heuristics derived from those measurements. They are deliberately conservative, and they are not a substitute for listening.
Who This Belongs To
EasyFader is a BrynSonic project, part of the wider collection of audio work: the musicians, the label and the books. This is the practical corner of it: the tools you open while working, rather than reading about.
