// | Example wrapper class to extract information from audio files |
// | through getID3(). |
// | |
// | getID3() returns a lot of information. Much of this information is |
// | not needed for the end-application. It is also possible that some |
// | users want to extract specific info. Modifying getID3() files is a |
// | bad idea, as modifications needs to be done to future versions of |
// | getID3(). |
// | |
// | Modify this wrapper class instead. This example extracts certain |
// | fields only and adds a new root value - encoder_options if possible. |
// | It also checks for mp3 files with wave headers. |
// +----------------------------------------------------------------------+
// | Example code: |
// | $au = new AudioInfo(); |
// | print_r($au->Info('file.flac'); |
