In-browser loudness normalization
Drop an audio file to normalize it using Integrated Loudness and TruePeak measurements. All in-browser, no leaky leaky of personal data.
For the challenge, and because it should exist.
Using ffmpeg.wasm for analysis and amplification. the loudnorm
dynamic mode is not used. If you want to see it, add a PR or file an issue.
No. Your browser does all the work.
Two passes. First pass measures loudness, second pass amplifies.
It doesn't. It ensures that neither value is exceeded. If your content has ridiculously high Integrated Loudness, the TP value will be below its limit, and vice versa. This is not an "automatic mastering plugin," it just does some analysis. And math. Not much math, tho.
Open an issue and I'll have a look.
Yep. Soundcloud link
