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.

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.

Analyze filesOpen Analyzer

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.

Normalize filesOpen Normalizer

TrimmerBETA

Trim, split and merge files — one by one on the waveform, or in batches by rules: cut start and end, split at markers, lengths or pauses, merge gaplessly with crossfades and cue markers.

ProcessorBETA

Run files one by one or in batches through a DSP chain in 32-bit float: filters, equalizers, compressors, saturation, gain, pan and width, clipper and true-peak limiter — written as text, previewed A/B and shared as a link.

Link BuilderBETA

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

Configure rulesOpen Link Builder

Export ViewerBETA

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