We need a six tracks WEB Multitrack Player: an application that is able to play up to six mp3 audio files at the same time.
No matter the technology that you're gonna use: the main requirement is that the tracks loaded must play in SYNC with METRONOMIC PRECISION (we found that Macromedia Flash seems to be useless for this purpose).
The application will be installed in a web page and it will read an URL of the type:
[url removed, login to view] &file1=filename1&file2=filename2&file3=….
Reading this URL the application got to take the names of the mp3 audio files (file1, file2, file3,…) as parameters and got to read the mp3 audio files inside a specific folder, loading each one of them on one of the six tracks.
Multitrack Player controls:
Master track: Play, Stop, Pause, Volume
Each track: Volume, Mute, Solo, Pan
UNIX (Linux) filesystem.
