MP3 Java Sound SPI.

• decider is powered by jlayer
• encoder is powered by java-lame

Both are in pure Java.

• maven

• decode
• encode

• Java Sound Programmer Guide

• encoder using https://github.com/nwaldispuehl/java-lame
• rename project as vavi-sound-mp3
• out source tag parser (use like vavi-util-tag)
• out source version
• jsidplay2:jump3r is the origin of java-lame (replace?)

No, JMF is not required. You just need a JVM JavaSound 1.0 compliant. (i.e. JVM1.3 or higher). However, MP3SPI is not JMF compliant.

Yes, it has been successfully tested with SHOUTCast and ICEcast streaming servers.

Yes, MP3SPI includes same features as JLayer.

Yes, It supports XING and VBRI VBR header too.

MP3SPI exposes many audio properties such as ID3v1/v2 frames, VBR, bitrate ... See online examples from MP3SPI homepage to learn how to get them. MP3SPI supports most used ID3v1.0, v1.1, v2.2, v2.3, v2.4 tags.

Call skip(long bytes) on AudioInputStream.

Run mvn test. You can update src/test/resources/test.mp3.properties file with the audio properties of the MP3 you want to use for testing.

Set the following system variable : "tritonus.TraceAudioFileReader=true" It means java.exe -Dtritonus.TraceAudioFileReader=true your.package.Player

Set the system property javazoom.spi.mpeg.encoding. e.g javazoom.spi.mpeg.encoding=MS932
