What information does the metadata viewer show?

File name, size, format, duration, sample rate, channels, and estimated bitrate.

Is the bitrate accurate?

The bitrate is estimated from file size and duration. Very accurate for CBR MP3 files, shows average for VBR files.

Any format your browser can decode — typically MP3, WAV, FLAC, OGG, AAC, and M4A.

Our MP3 metadata viewer extracts and displays all key technical information from your audio file:

Verify audio quality — confirm a file is genuine 320kbps before adding to your DJ library
Check compatibility — verify sample rate before loading into a DAW or DJ software
Spot re-encoded files — identify low-quality files falsely labeled as high bitrate
Library management — quickly check the specs of any audio file
Format verification — confirm the actual format of a file regardless of its extension

A common issue in DJ libraries is re-encoded audio — a low-quality file converted to a higher bitrate. Signs:

Bitrate shows 320kbps but the file sounds muffled
File size is smaller than expected for a 320kbps file of that duration
Use our Frequency Analyzer to check — re-encoded files show a sharp cutoff in high frequencies
