FLAC allows third-party applications to register an ID for use with FLAC APPLICATION metadata blocks
. Contact the FLAC-dev mailinglist
to register an ID or to change an existing ID. Your request should at least contain the application ID, application name and a contact e-mail address. An application URL and specification URL should be mentioned too, if applicable.
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.
