This program permits you to use FFT under Matlab platform, you may change the fine function used as reference to calculate its FFT to any other function.Hope it helps you.

空间谱估计（MUSIC）算法的MATLAB仿真分析(Spatial spectrum estimation (MUSIC) algorithm MATLAB simulation analysis)

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.
