Introducing the AS3 Karaoke player

I decided to post one personal project that I did last year. The “AS3 Karaoke: Player is a experimental online mp3/cdg player. It`s been a pleasure developing it but unfortunately I have no time to finish it so whoever is interested in continuing please feel free to do so.

A little bit about the project. It started as a bet between me and a friend. We were planning a karaoke party and we were using the popular application Karafun to test our songs. I said that this can be done in flash/as3. He said that is not possible. And there I had a challenge.

Project evolution :
– Finding the cdg file specifications ( not a lot of references );
– Writing code for loading *.cdg files into bytes arrays. Parsing and displaying data into Bitmap.
- performance optimization for intensive bitmap manipulation.
- synchronizing mp3 playback with cdg parser;
- cdg “Zip” compression and decompression for faster download speed.
- implementing seek function;
- implementing playback speed control;
- implement pitch modifier;
- implement equalizer;
- add fancy visualizer ( that kills slow preprocessors );
- creating playlist with search, arrange, resize, next previous features;
- record voice and mp3
- encode recoding into wave, or mp3 (using alchemy encoder);

This project was done in my spare time as a proof of concept and is very far from a production level application.

DEMO after you select a song give it some time to load.
