Taglib Bindings for Racket🔗 i

This package contains a set of Racket bindings for the Taglib library for reading metadata for popular audio formats. The bindings are for the C library, which only supports the limited abstract API of Taglib.

Requires the taglibc library.

This package has been tested on Debian GNU/Linux. If you have taglibc installed and this FFI binding cannot find it, please e-mail me about your setup so that I can improve the library.

(require taglib ) package: taglib
