Local-first audio analysis

Waves, verified.

Analyze audio directly in your browser: length, peaks, LUFS, LRA, short-term and momentary maxima, mono and phase checks, plus CSV, JSON & PDF report export. Files stay local on your device — nothing is uploaded.

Audio AnalyzerBETA

Drop in one or more audio files to inspect duration, sample and true peaks, integrated loudness, LRA, short-term and momentary maxima, mono and phase correlation. Export results as CSV, JSON or a PDF report.

Audio NormalizerBETA

Bring files to a loudness or peak target with an optional true-peak limiter, or just convert them. Export WAV, FLAC, MP3, Opus or AAC — tags and cover art are kept and editable.

Export ViewerALPHA

Load an analyzer JSON or CSV export to review saved measurements and visualizations. Inspect results without reprocessing the original audio.

Link BuilderALPHA

Build shareable links: analyzer rules (loudness, peak, length, dynamics, phase) or normalizer settings (target, limiter, format, bitrate) — also as short links.
