Easy audio

==========

Overview

-------

**NB**: 25.04.2022: `easy-audio/utils` system was merged to

`easy-audio/core`. Global nicknames were removed from all packages loaded with

`(asdf:load-system :easy-audio)`. Use full names (like `easy-audio.flac` instead

of `flac`) or local nicknames. The version was bumped to `1.1`.

Easy audio is my small but slowly growing pack of audio decoders. It can

help you decode audio files and also provides easy access to metadata.

It has:

 * FLAC format support. Can decode anything, supports almost all metadata

   blocks.

 * Partial support for WavPack format. Can read and decode non-hybrid

   lossless WavPack data which is the most used, anyway. Support many

   metadata blocks (though they are not as useful as in FLAC).

 * Partial wav container support, can read uncompressed, a-law compressed

   and mu-law compressed audio data.

 * OGG container support, but, unfortunately, without Vorbis decoder.

   Can read FLAC compressed data inside OGG container.

 * APEv2 tags support (currently only in wavpack files).

 * Partial APE support. Only the most recent version (3.99) is supported, also

   there is no integrity checks.

Documentation

------------

Documentation for `easy-audio` is automatically generated by `codex` (my version

of [codex](https://github.com/shamazmazum/codex) and

[docparser](https://github.com/shamazmazum/docparser) is needed). Just run

`(codex:document :easy-audio)`. You can also visit a

[project page](http://shamazmazum.github.io/easy-audio/).
