AUDIO INSPECTOR / KNOW YOUR RECORDING

Look a little closer before you press play.

Understand a recording’s duration, decoded channels and sample peaks. No upload, no AI model, no account.

Your waveform will appear here.

The numbers are a starting point. Keep listening.

What this tool measures

The inspector reads browser-decoded samples and computes duration, sample peak, whole-file RMS and a count of samples with absolute amplitude at least 0.999. The overview draws amplitude envelopes in time buckets. Reports are saved locally rather than sent to a server.

What it cannot establish

This is not a LUFS, true-peak, codec or original-sample-rate detector. Browsers may resample during decoding. Near-full-scale samples do not prove the original recording clipped or establish musical quality. The current limits are 64 MB and 10 minutes; format support depends on the browser decoder.
