Looping audio is a matter of, well, generating the same sequence of samples over and over again. The loop might not have the same length as the sample window that you have to supply when the Flash Player requests more audio data, so there’s a slight bit of math involved, but not much.

Hi Joe,

Do you have any tip on loop audio in Flash?

Hi Joe,

Just wondering how your’e getting on with your ’standing wave’ project.

I have a number of other higher-priority projects going on, but I hope to release StandingWave by the end of the year.

Hi Joe!

Any plans for releasing the code of StandingWave?

Regards / Jonas

[...] of dynamically-generated sound, but also some experiments that show how it can still be done). This framework also looks promising and has a nice sample-based example to show what the guy wants to do. [...]

I never came across this post before I read your comment at createdigitalmusic.com
It is good to see, that other people are also putting research on this subject even you have to take a lot of unusual efforts to it. If you are interested to collaborate with our team, please contact me.

This is awesome Joe. I’ve done a bit of work on tempo detection in AS3 and was very dismayed with the lack of support for waveform manipulation and especially synthesis. I’d love to have a chance to play with StandingWave – please release it!

I guess it would be possible, but MP3 would have to be decoded in non-native AS3 code which I suspect would probably be unacceptable in terms of performance. You are right, all the internal audio in StandingWave is PCM — it’s the only way to go for raw speed.

Would it be possible to use some of your work to maybe feed an MP3 stream to sound?

Basically, avoid the flash streaming memory leak by doing the streaming manually and pumping the bytecode into the audio stream?

I’m guessing at the end of the chain we’re down to PCM and MP3 would have to be decoded by its own class?
