@MikkoP I am searching for any Java library/API which will convert mp3 to PCM... – Tushar Ahirrao Sep 15 '12 at 13:39

This question where the OP tries the exact opposite might be interesting (as soon as there is a solution): http://stackoverflow.com/questions/12424659/flex-java-byte-to-mp3/12424832#12424832 – Philipp Sep 15 '12 at 13:49

@Philipp There has been a J2SE+JMF solution to this specific requirement since Java 1.3. – Andrew Thompson Sep 15 '12 at 22:54

@Sri Maybe you should add JavaZoom as an answer. – Andrew Thompson Sep 15 '12 at 22:56

- Get the
mp3plugin.jarof the JMF. - Add it to the run-time class-path of the app. to provide a decoder SPI for MP3.
- Get an
AudioInputStreamfor the MP3 from theAudioSystemof Java Sound. - Convert it to PCM using
getAudioInputStream(AudioFormat,AudioInputStream).

Sorry for the necropost but, how do I know the mp3plugin.jar is added to the run-time class-path? I have it under referenced libraries, should that be enough? I ask because this solution isn't working for my mp3 file. – Perry Monschau Aug 11 '18 at 10:15

@PerryMonschau *"how do I know the mp3plugin.jar is added to the run-time class-path?"* A good sign the MP3 Service Provider Interface is on the class path is that the app. can read an MP3 (just like it can read a WAV ot any other sound file type Java supports without it). – Andrew Thompson Aug 11 '18 at 10:43
