PHP Class or Function for WAV files - anyone know of one?
I'm working on an online application for a client that involves working with media files, such as MP3, WAV and MP4 files.
I would like to be able to extract Meta information from the WAV and MP4 files - particularly track run time, licencing and encoding information.
I already have a PHP class that does a fine job with MP3 files (ID3 meta information) so I'm good with that.
Apparently WAV files use header information encoded in "Broadcast Wave Format" or BWF. I have Googled but can't find any code samples for using PHP to read BWF meta information from a WAV file.
Is anyone familiar with any code, a PHP Class or Function, that can do this - read BWF information when given a WAV file?
I'd also be interested in reading meta information from MP4 files as well - run time, frames per second, things like that.
Thanks
Bill
