Graphing GPU_FFT - Raspberry Pi Forums

hello, i've been looking through gpu_fft library , want use create close real time graphing program displays amplitude versus frequency of incoming audio signal wolfson raspberry pi audio card. looking through program have 2 questions:

• i cannot find place in included files feed input program, whether bean adc sample wav file or else
  cannot find documentation on setup , use of gpu_fft
  cannot find rpi graphing utility can display using terminal

have searched forums , cannot find real explanation beyond sample files hello_fft , hello_fft2d, did not much. if approaching wrong perspective, please let me know, idealy liek feed program sample external adc can process using gpu_fft program , display using self written program or more advanced rpi graphing utility.

it nothing more demo program show how use gpu_fft api.

need write own program uses api useful.

if reasonable c programmer not hard do.
