However I doubt that a thing as complex as mp3 conversion can be translated on the PB kernels that in current version don't support loops. If you know a good open source C library for mp3 encoding you can try to compile it using Alchemy and give it a try. It might work a little faster than an algorithm implemented in AS3 but still it will run on a single core. If you don't have an MP3 algorithm currently then I strongly recommend this way as you have a decent chance of having something working in maybe less than a week (maybe even days if you are good with make files and C compilation).

Currently working at a project where i need to make mp3 encoding on the client. Just wanted to ask you if you own or maybe point me to some sources, where i can do this using Pixel Bender. I want to use Pixel Bender, thinking that the encoding will be much faster than regular as3, or using some alchemy library. Thanks, Marius Bratu. P.S. Great post! Hello:)

added public for the played var
added void as the return type of the set function myProp

\"Data Binding will not be able to detect assignments to myBmp\"
\"Data Binding will not be able to detect assignments to width\"

I am sure that there is something i am doing wrong, but i cant find it
thanks in advance

In the source code for the sampleSound program, you don't ever call or reference the OnSampleData() function which uses the pixelBender file. you only call onSampleData2(). Can you explain or update how you make use of the pixelBender file to mix audio? Actually, I have a question.

There are no complete tutorials on the subject. everyone just has little bits and and tips on how to do it.
