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.
