A utility for reading metadata embedded in FLAC audio files.
This utility was created as an alternative to flac-parser. They do the same thing currently, as both projects parse FLAC metadata. However,
flac-metadata goes about it a much different way, which results in much more concise code, and eventually, it should be faster. Eventually, because one of its dependencies,
bitio, needs some additional performance improvements when reading sequences of bytes, which the author is aware of and working towards a solution. In addition,
flac-parser will separate paths when/if
flac-parser gains support for decoding audio frames. In short, I wrote
flac-metadata to see how concise I could do it, and to try out a different parsing method that I used to write pngload.
This system is not yet available to be installed automatically with Quicklisp. To manually install using Quicklisp, clone this repository into your local-projects directory and issue the following in your REPL:
You can read metadata from a FLAC audio file in one of two ways.
The following will return an object, representing the concrete syntax tree of the FLAC specification. With it, you can access the metadata you wish:
Alternatively, you may dump out the metadata pretty-printed:
(dump-file (load-file #p"/path/to/file.flac"))
