Currently I´m working on a flash/flex project where users can create music in real-time. The most challenging parts of this project was to create a smooth playback stream without any chops. After some work I managed to do this in flash through the amazing popforge library by André Michelle and Joa Ebert. Though the current version of popforge won´t work very well on all operative systems out there the coming of Astro (fp 10) will successfully bridge this issue. If you haven´t joined the struggle to make Adobe realize that dynamic audio is the future of flash be sure to do it. Even thought Tinic Oro of the Flash developer team brought us great news about a month ago there is still work to be done to make the Flash player a solid choice for dynamic real time audio manipulation.
I Agree! Have now joined the struggle
