Some feedback on this code would be nice

https://github.com/bLightZP/Audio-File-H...udioDB.com

The algorithm itself is based on a modified version of the OpenSubtitles.org code:
http://www.yanniel.info/2012/01/open-sub...elphi.html

Unlike the OpenSubtitles.org hash, in this case, hash offset position within the file is determined by the file size to support smaller file sizes, while allowing larger TAG data (embedded images) to be changed without affecting both hashes (unless the embedded image changes the file size from under 2048KiB to over 2048KiB).

Windows app here:

The idea is it should make an XML file with a load of hashes for your music. Its virtually instant as its using slightly modified opensubtitles code.

Any comments on the approach?

Example

PHP Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
