Audio Loudness Analyzer

Inspect decoded audio levels and gated K-weighted loudness estimates without uploading the source; results are diagnostic, not a certified broadcast measurement.

Browser-local audio workflow

v10.82 connects single-track editing, cutting/joining, level and dynamics processing, waveform/spectrum inspection, loudness and clipping diagnostics, channel/sample-rate conversion, recording, looping, and splitting. Local processing avoids an upload step where the browser can decode the file.

Codec and measurement boundaries

Browser decoding differs across Safari, Chrome, Firefox, iOS, and Android. Rendered edits are exported as WAV unless a tool explicitly states another supported container. Loudness analysis is a practical BS.1770-style estimate rather than a certified meter, and sample clipping checks do not replace true-peak oversampling.

How to use this Audio Loudness Analyzer

Analyze peak, RMS, crest factor, and a browser-local BS.1770-style integrated loudness estimate.

  1. Enter, paste, upload, or choose the inputs shown in the tool above.
  2. Adjust the available options for the result you need.
  3. Review the output before copying, downloading, or using it elsewhere.

Practical tips and limits

Keep the original audio file and listen through the exported result. Browser decoding support and loudness behavior can vary by format and device.
