FLAC allows third-party applications to register an ID for use with FLAC APPLICATION metadata blocks. Use the following form to request an ID, or to submit a change to an existing ID.
The ID request should be 8 hexadecimal digits and not conflict with any existing IDs (see the table below for all currently registered IDs). This 32-bit number will be stored big-endian in the block.
Information about your application (but not your e-mail address) will show up on this page in the ID directory. You can also provide a URL to your application and a URL reference to the specification of your application's APPLICATION block.
You will be notified via e-mail about your submission.
Here is a list of all registered IDs and their applications:
