I have plan to use libopenmpt.js for creating web based game. I am using tool that make non programmer like me to fullfilll the task. The only problem is the tool/engine doesn't support module music format and I prefer it over ogg because of filesize. Before I invest my money for programmer, I have 2 qustions.
libopenmpt.js comes at a size cost itself, thus you probably have to include that also in your calculations (it may very well still be less in size than ogg or mp3 tracks).
1. How much computer resources are needed to playback format like IT or MPTM compared to MIDI or OGG Vorbis?
2. How fast is libopenmpt.js to playback module music file? Can it be use for real time playback without lag or performance penalty?
Even though we would certainly like to see people experimenting with libopenmpt.js in web-based games, I am not quite sure if I could recommend that usage. You will certainly have less hassle if you are using AAC or Ogg Vorbis playback provided by the browsers and your game engine.
