Valid MP3 or not

Blobby66 · 16th September 2002, 21:31

Does anyone know how to test if an mp3 file is a REAL mp3 file and not just a renamed text file or something? My app hangs when it tries to play a test file disguised as a .mp3 file and i need to trap this.
Ive tried reading the .TAG of the mp3 file but even valid mp3 files dont contain the .tag of "TAG". Must be something i can check for before initiating playback. Thanks for any feed PS. Im using VB but as long as the principle works i can adapt it. Ta

I'd guess you'd need to look at the Mp3's header and make sure it isn't corrupted, search google for "mp3 header format" for an idea of how mp3s headers work. Here's a link to my google search

Search Google for "Mp3 Header Format" Here
