10/01/06 — At the request of readers, Chapin Information Services (CIS) is releasing a program described last week at p2pnet.net.

A small utility had been created to prove the presence and integrity of MP3 audio data downloaded from public Internet servers.

MP3 Extractor v1.0

This first public version differs from the original utility. It has been re-designed so that it does not involve the ASF media format.

Rather than using an encapsulation decoder, MP3 Extractor uses the MP3 format to search for fragmented audio frames. The procedure is fast and very simple. It works with predictable patterns. Future versions may add more complex logic.

MP3 Extractor is an open source utility, free for private use.
