Hi, Quite informative article on not so well explored subject :) It's very hard to find any examples in this subject... Could you be so nice and post some code you've mentioned in the article ? BTW. Do you think that's possible to calculate FFT via PixelBender in favour of performance gain ?

I would like to add a little more facts about Pixel Bender. It delivers a common image and video processing infrastructure which will facilitate automatic runtime optimization on heterogeneous hardware. Pixel Bender kernel language can be used for implementation of image processing algorithms in a hardware-independent manner. Thus it saves valuable time and energy. Regarding the question mentioned in the blog I have asked one of my friends who is an expert in these things. He will be mailing me within two days.

Hi,

I just put code and working example.

Sorry for missing this out :)

If you want to try it, you need to set correct path to your mp3 file in Main.as (line 125).

If there is any problem just ask.

P.S. I hope, it would be possible to speed up with PixelBender. I just started investigating on it. It mainly depends what PB can accept as input. I think it is addressing only few pixels in image, so it seems it cannot work with big arrays that represents audio samples :(

We can play with it together and see if it works :)
In source code you have FFT algorithm
