Abstract
This paper introduces the principle of Audio analyzer, analyses the method of analyzing audio spectrum by Fast Fourier Transform. It puts forward the scheme of audio analysis over the audio signal using ARM7 and UDA1341TS, adopting the technology of double cache and DMA to increase speed of data processing. A system of collecting audio signal and audio analysis is designed based on this scheme.
