Audio file info

Upload an audio file and inspect its technical details — format, codec, bitrate, sample rate, channels, and duration.

Everything your audio file knows about itself

Drop in a file and read its technical card: container format, codec, bitrate, sample rate, channel count, and duration. The file is parsed locally in your browser, so inspection is instant and private.

This works across formats: MP3, FLAC, WAV, M4A, OGG, AAC, and more, including files with misleading extensions.

Why inspect a file

Verifying a "lossless" purchase really is lossless, checking whether a recording meets a platform’s spec before uploading, diagnosing files that refuse to play, and confirming what an unlabeled file actually contains.

Frequently asked questions

The extension says MP3 but playback fails. Can this tell me why?

Usually yes. The inspector reads the actual container and codec, which often reveals a renamed or mislabeled file.

Is the file uploaded for analysis?

No, parsing happens in your browser; the file never leaves your device.
