利用matlab提供的工具来采集和分析声音信号的频谱,内含声音文件ding.wav(Using matlab to provide tools to collect and analyze the voice signal spectrum)
wm8731的使用,用于音频信号的采集或者产生(wm8731 use for audio signal acquisition or produce)
音乐合并,能合并多种文件格式,包括MP3等(Music merger to merge a variety of file formats, including MP3, etc.)
In this article I ll show you how to add Text-to-Speech (TTS) capabilities to your program. You ll be able to do it with, essentially, 1 line of code, using the familiar standard ostream syntax.

Speex is an Open Source/Free Software patent-free audio compression format designed for speech.(Speex is an Open Source/Free Software patent-free audio compression format designed for speech.)
网络语音传输,采用系统级wav函数采集音频加socket做网络传输(The network speech transmission, uses the system-level wav function gathering audio frequency to add socket to make the network transmission )
本实验旨在了解如何将模拟的声音信号转化为数字信号,重点掌握在数字声音四个重要的技术指标:采样速率、量化比特数、声道数和编码方法。(This experiment aimed at understanding how analog voice signal into a digital signal, with a focus in the hands of digital audio technology to four key indicators: the sampling rate, quantization bits, the number of channels and the encoding method.)
自己完全封装过的Speex语音解压缩源代码。生成d(Completely off their own package Speex voice extract the source code. Generate d)
通过调用waveopen 函数获取pcm格式的声音文件的声道波形及其动量音量显示(Waveopen by calling the function to get the pcm format sound files and their momentum volume channel waveform display)
说明: 本程序演示了如何对wav进行分析并根据其数据模拟出波型图.再对其波型图进行操作.移动或者修改或者重叠.对有这方面接触的VB程序员很有帮助.(This procedure demonstrates how to wav analysis and data in accordance with its simulated waveform Fig. And then its wave-type plans to operate. Mobile or modify or overlap. For there is very helpful to contact VB programmers.)
说明: 小波包分析提取振动信号中的特征频率,以及能量谱分析计算-wavelet packet analysis vibration signal from the characteristic frequency, and the energy spectrum analysis (Extraction of wavelet packet analysis in the vibration signal characteristic frequency, as well as the calculation of the energy spectrum analysis-wavelet packet analysis vibration signal from the characteristic frequency, and the energy spectrum analysis)
说明: 船舶在海洋航行不可避免要受到扰动,这是一个海洋环境干扰的仿真程序。(Ships sailing in the oceans will inevitably be subject to disturbance, this is an interference with the marine environment of the simulation program.)
这个工具包主要计算音乐拍子,里面还有计算音乐信号能量,基音频率等功能。(The main calculation of this toolkit music beat, along with the calculation music signal energy, pitch frequency and other functions.)
声卡数据采集,LabVIEW图形化编程例程书籍的例程源代码,可以直接使用,或修改部分加入自己的工程,功能稳定。(Sound card data acquisition, LabVIEW graphical programming routines routines book source code, can be used directly, or to amend section to be included in their own works, the functional stability.)
本程序可以同时进行两路音频文件的播放和录制(运行程序前要确定电脑有两个声卡)。可以作为音频开发的参考程序(This procedure can be done two-way audio file playback and recording (prior to running the program to determine the computer has two sound cards). Can be used as a reference audio development process)
