这个函数就是用来进行离散的DFT运算了。它可以指定运算的长度。...

这里主要我自己成果，是关于语音编码的，个人认为还可以，里面程序上传前经本人调试确认完全可用．有对多级矢量量化的程序（这个网上很少有），还有就是对MELP多帧参数的提取（这些网上也少见），还有就是统计子带清浊音概率的，还有一个我搜集的认为比较好的关于语音编码的英文文档．-Here the main results of my own, on the speech coding, and personally think that can also be inside the procedure before From my debugging can be used to confirm complete. There are of multi-stage vector quantization process (the online few), there is a multi-frame MELP parameters of the extraction (which are online also rare), there is statistical subband audio Qingzhuo probability, there is one I have collected think of a better speech coding on the document in English.

matlab的时频分析工具箱，希望在对信号的分析上可以帮助到大家。-the time-frequency analysis matlab toolbox, hope that the analysis of the signal can help to everyone.

这是一个公式编辑器，编写一个微型非所见即所得公式编辑器，对于输入的源代码进行分析，判断语法是否正确，如果正确则输出对应的公式。 -This is a formula editor, the preparation of a miniature non-WYSIWYG formula editor, enter the source code for an analysis to determine whether the grammar is correct, if the correct output corresponding to the formula.

应用背景通过语音识别，并通过MP3播放，支持SD卡存储。关键技术LD3320 非特定语音识别  STM32 嵌入式

特征分析对于声音信号的处理非常有用，希望这个能对大家有用-Feature Analysis for the audio signal processing is very useful, hope this will be useful to everyone

ica 权威paris在很久以前写的ica算法程序，稍作修改可以用于声音信号识别。-Paris, one of the authorities of ICA, created the program at long time ago. It can be used to recognise speech signal if modify a little.

完成基于MFCC的语音识别系统仿真，文件中带有完成语音识别训练的源文件-Completion of MFCC-based speech recognition system simulation, document the completion of speech recognition training with the source file

豪杰解霸、Winamp等播放软件中都有频谱分析仪。我们有时在编写一个多媒体软件时，总想实现这种功能，然而在网上介绍这方面的却比较少，现在用VB做了一个。希望对编程有所帮助。有些地方不完善，请大家提出意见。
