Identifying silence at the end of an mp3 using java

Question

Trying to detect silence at the end of audio in mp3 format, well all formats would be useful but mp3 format is the most important

Answer 1

The only way I know of to reliably detect silence at the end of a sound clip is to convert it to a PCM format and do one of the following calculations checking for a certain minimum cut-off amplitude.

• Decibels (dB)
• Root Mean Square (RMS)

I've never managed to implement dB, but RMS is relatively simple, and should work for this use. I used it for the small bars seen on the lower left/right of trace area of the DukeBox player.

As to how to do any of that with MP3 format, see the details on the Java Sound info. page.
