C audio spectrum analyser

[Jackie]

Hello guys I tought there is alot of skilled C coders and I would use a bit of help with one project.
I have evaluation board/kit Davinci TMS320DM6437EVM from Ti. I have to program in C audio spectrum analyser an debug it for this board in CCstudio. I have to use audio line in for audio input, make DCT - Discrete cosine transform for spectrum analyse and display result with LDC display conected to analog video output (composite). It has to be running continuously.
There would be a reward for the skilled coder but I have deadline next friday we are kind of sure that someone did it for this board already but we couldnt find it so even if you can´t code it but can point us some direction where we could find it it would be great thank you for any help guys
