What this audio tool does

Inspect an audio file's container clues, codec support, duration, channels, and sample rate without uploading it. Everything stays on this device while the page is open.

The page uses browser-native audio APIs and derives every displayed result from the current input or interaction.

Browser codec and microphone support varies. Unsupported operations stop with a specific message instead of creating a mislabeled file.

Supported formats and limits

Files must be decodable by the current browser. WAV is used for sample-accurate edited output; reports use plain text or CSV.

Input	Browser-decodable audio or live interaction
Privacy	Local browser session
Output	Real WAV, recording, or report where applicable

Example and practical tips

For example, use audio format detector on a short test first so you can confirm the settings before working with a long recording.

Keep the tab open during processing.
Preview the result before downloading.
Use an unprotected source file.

Frequently asked questions

Does Audio Format Detector upload my audio anywhere?

No. The work happens locally in this browser, and the selected file is not sent to a server.

Which browsers work best with Audio Format Detector?

A current Chromium, Firefox, or Safari release with the required Web Audio features works best. The page reports a clear error when a needed feature is missing.

What happens if my audio file cannot be decoded?

The tool stops and explains that the file is unsupported or damaged instead of producing a made-up result.

Can I use the result from Audio Format Detector in another editor?

Yes. Any downloadable output is a real file created from the current session and can be opened in compatible audio software.

Is there a practical file-size limit for Audio Format Detector?

Large files use substantial memory because browsers decode audio in RAM. Closing other heavy tabs helps with longer recordings.
