What this audio tool does
See the real sample waveform and measure peak and RMS levels locally.
The tool reads real samples or a live media stream, performs the selected operation, and creates a new downloadable Blob.
Large files use significant memory. Browser codec and recording support varies, so unsupported operations return a clear error instead of a fake file.
Supported formats and limits
The exact set depends on the codecs built into your browser.
| Input | Browser-decodable media |
|---|---|
| Processing | Local Web Audio APIs |
| Limit | Short and medium files recommended |
Example and practical tips
Start with a short file while testing settings. Listen on headphones, compare the original and result, and keep the original as your master copy.
Frequently asked questions

Which files work with audio waveform viewer?
Files that your browser can decode are supported. Codec support differs between Chrome, Edge, Safari, and Firefox.
Does audio waveform viewer change the original file?
