Sync-Licensing Metadata Injector
Music supervisors routinely discard untagged audio files. Write standard BWF and RIFF INFO tags-including ISRC and PRO affiliations-directly into the binary header of your .WAV masters. 100% offline.

Zero server uploads. Your unreleased master never leaves your computer.
How It Works (Technical Overview)
Most web-based tagging utilities require you to upload your unreleased, high-resolution masters to a remote server. For commercial sync licensing and major label work, that represents a severe security liability.
This tool operates entirely client-side. When you drop a file into the browser, it uses JavaScript's native DataView API to read the binary structure of the RIFF WAVE header. It then generates an industry-standard LIST INFO chunk containing your ISRC, PRO affiliations, and composer splits, appending the data directly to the binary buffer.
The result is a fully compliant Broadcast Wave Format (BWF) file that music supervisors can index in their databases, processed locally with zero network requests.
Why do you need to inject metadata?
If you are sending your music to music supervisors for TV, film, or commercials, your MP3 files need to be packed with information. A supervisor might download hundreds of songs a week. If they like your song but your file is just named "Track 1.mp3" and has no contact info attached to it, they will never be able to pay you.
This tool lets you embed your name, email, phone number, and publishing details permanently into the audio file's metadata.
How to tag your files
Upload your mixed MP3 or WAV file. Fill out the form with your artist name, the song title, the BPM, the mood of the track, and most importantly, your direct contact information.
When you hit inject, we embed all of that data deep into the ID3 tags of the file. No matter where the file goes or who downloads it, they will always be able to open the properties and see exactly who owns the song and how to license it.
Frequently Asked Questions
Why do music supervisors care about metadata?
Music supervisors receive hundreds of songs a day. If they like your song but your file doesn't have your email address embedded in it, they will just move on to the next track rather than trying to track you down.
What is a PRO and CAE number?
PRO stands for Performing Rights Organization (like ASCAP or BMI). When you register with them as a writer, they give you a unique CAE/IPI number. Supervisors use this to ensure you get paid when your song plays on TV.
Does this work for instrumental versions?
Yes. You should always include the word "(Instrumental)" in the title field, and make sure to embed the exact same contact and publishing metadata as the vocal version.
