This library is a general purpose audio library built on top of the Java Sound API. It comprises wrappers for JSA's
midi packages in the corresponding namespaces. It also include a higher level API for audio playback in the
midi namespace is a work in progress.
Playing a wave file.
(play (->stream "~/test.wav"))
Playing a MP3 file, this example requires some extra libraries, see "Installation" below.
(-> (->stream "~/test.mp3") decode play)
Decoding a MP3 file and writing it to a WAVE file.
(-> (->stream "~/test.mp3") decode (write :wave "~/test.wav"))
Skipping a specific amount of bytes.
(-> (->stream "~/test.mp3") (skip 1000) decode play)
Skipping a stream with a ratio of its length.
(let [s (->stream "~/test.mp3")
skip (skipper s)]
(-> s decode play))
Playing the resulting stream from applying the identity function from 0 to 99999. The given function output will be converted to bytes.
(play (->stream identity 100000))
A simple headless MP3 player that support a basic set of command: play, stop, pause, next, previous, random and close. To use it, you'll need some external libraries as explained below. It should work for any file format given the corresponding SPI and adding their extensions to
- Skipping an encoded stream then writing its decoded output to a file using the write function will produce an empty file.
This library is available on Clojars. To use clj-audio in your Leiningen project, add the following dependency.
For encoded file type support, you'll need to add the corresponding Service Provider Interface (SPI) which are simple jar files. First you'll have to get the Tritonus plug-ins shared classes (tritonus_share-*.jar) which is needed by most JSA's SPI. Then to get MP3 support for example, you can grab the latest versions of JLayer and MP3SPI.
