How to get the size and duration of an mp3 file?

Question

I need to calculate the total length of an mp3 file.

Currently I am using a PHP class which I found @ http://www.zedwood.com/article/php-calculate-duration-of-mp3.

A Famous and Very SPI that you can use MP3 SPI and the code is also very simple

File file = new File("filename.mp3");
AudioFileFormat baseFileFormat = AudioSystem.getAudioFileFormat(file);
Map properties = baseFileFormat.properties();
Long duration = (Long) properties.get("duration");
