Aquila started as a way for me to download various torrents without actually visit those pop up sites. It has a very simple interface but underneath it lies about thousand lines of code, with multi thread support for efficient GUI response and more.

When a file is dropped the program takes an audio sample from the music-file which it send to TRM-server and generates an audio fingerprint witch it sends back. MusicBrainz then sends the correct information/metadata (such as artist, song and album) back to the QuickNamer program. QuickNamer renames your mp3s and saves the retrived info in the files.
