audio spectrum analysis (spectrogram)(repost)

(speech or music)

-the application spectrum analize a WAVE or live line-in sequence

-using FFT (adjustable size) or LPC or better recommandation ,colors spectrum or gray scale

-scale range spectrogram from 20 Hz to 20000 Hz or higer.

-graphical representation or data result should be abble to be outputed to an other module or simply screen displayed.

-display, waveform and spectrogram along with a ruler which gives a measure of elapsed time ,beat, tempo auto calculation.

-option to split sequence into (8 16 32 64 or peak marker).

This spectrogram would be the core unit of a project , and i want something really compatible and common language (C ,c++ etc) in order to re-use this module into a larger project. Spectrogram would output data , to an other analyse module that would find the closes match from a database of pre-analyse audio sequence (once match found, the module would play' the video or .wav file or list display all the closes match whit % details ) -The data receving module-:: This the module that would analyse data given by the spectrogram. First i tough of doing image recognition on the spectrogram display image , but i think that "core data" recognition will give better more optimize live performance. *(recommendations) -here some specification-: -most of the sequences will be 16-bit/[url removed, login to view] .wav files , and mic line-in from a sound card. -Elapsed time ,beat, tempo auto calculation for all sequences. -i want an "original" commercial code all rights to my company\\ even do lots of code got a % of similitude....*(negotiation) -FFT implementation can be taken from open source. -option to split sequence into (8 16 32 64 or peak marker). -power-of-2 implementation or 0 , you recommend
