The approach I was thinking of was something like this: <http://acko.net/blog/javascript-audio-synthesis-with-html-5> You generate the audio data, attach a WAV header and play it with an audio element. It's a bit hacky but does work. Ideally there would be an actual audio API allowing generating and playing samples - this is something a lot of people are interested in and they're exploring possibly API's for standardisation. > Can you say a bit more?

Technically you could load the .WAV file using XMLHttpRequest, get the raw data, manipulate it and create data URL's containing the modified data. Although not using WAV I have an example of loading a file containing binary data and parsing it (using an Ogg file for the example) here: <http://www.bluishcoder.co.nz/2009/06/05/reading-ogg-files-with-javascript.html> Another approach if you don't mind using flash is to use one of the Flash based audio libraries: http://www.schillmania.com/projects/soundmanager2/ Chris. -- http://www.bluishcoder.co.nz _______________________________________________ lively-kernel mailing list [email protected] http://lists.hpi.uni-potsdam.de/listinfo/lively-kernel
