Supports WAV, Broadcast WAV (BWF), and MP3 files
How it works
Drop a WAV or MP3 file into the editor and it reads the file's metadata instantly — format, sample rate, bit depth, duration, and any existing ISRC code. If an ISRC is already embedded, it shows up pre-filled so you can verify or update it. If there isn't one, type it in and hit write.
For WAV files, ISRC codes are stored in the Broadcast Wave Format (BWF) chunk following the EBU Tech 3352 standard. For MP3s, they're written to the ID3v2 TSRC frame. Both are industry-standard methods that distributors and PROs recognize.
Everything runs locally in your browser — your files never leave your device. The editor reads the raw bytes, modifies only the metadata chunk, and gives you a clean download. No server, no account, no waiting.
What is an ISRC code?
The International Standard Recording Code is a 12-character identifier assigned to individual sound recordings. It's not tied to a song — it's tied to a specific recording of a song. A remix, a live version, and a studio version of the same track each get their own ISRC.
Distributors like DistroKid, TuneCore, and CD Baby require ISRCs when you submit music. Streaming platforms use them to track plays and route royalty payments. Embedding the code directly in your audio file means it travels with the recording wherever the file goes — no separate spreadsheet needed.
If you're managing ISRC codes across multiple recordings, Songkeeper lets you track ISRCs alongside your songs, recordings, and release metadata — so everything stays in one place.
