使用DELPHI实现文本文件显示和声音同步播放

实现了 从多媒体文件中抽取声音流 并写入令一个文件 对于初学者还不错-MUTIL MEDIA

用于语音视频聊天的类,非常方便的实现将录制的PCM格式的语音,压缩,解压,视频采集,播放-Voice Chat Class. Very easy to implement record PCM format voice, encode/decode,gather vedio and play back.

录音机程序,VISUAL BASIC代码-tape recorders procedures VISUAL BASIC code

音频文件格式，包括WAV、ADPCM、CDR，另外还有AU文件格式，后面的音频数据即可以是一般的数据，也支持按CCITT G.721 (32 kbit/s) 和 G.723 (24/40 kbit/s)格式压缩好的音频数据-audio file formats, including WAV, ADPCM, CDR, another AU document format, as the audio data that may be general information, and support by CCITT G.721 (32 kbit/s) and G.723 (nometastases kbit/s) good audio compression format data

在噪声环境下语音信号的增强 语音信号为读入的声音文件 噪声为正态随机噪声-In the noisy environment of the enhanced voice signal voice signal for the read noise of the sound files for the normal random noise

这是一个很专业的VC++实现adpcm编码的工程源代码.-This is a very professional VC++ projects to achieve adpcm coding source code.

To run this sample you must have a sound card connected to the PC. If you want to see some signal you must plug a Microphone to the mic connector of the sound card. If you don t have a mic you can plug an hearphone to the mic connector and speak closely in it.

psola的matlab源码,这里提醒各位，psola的调整算法，有很大的局限性，一方面是准确的标注很难获得，另一方面，psola调整之后，往往会带来比较大的负面作用，包括噪音和机器声，使得合成的质量会有明显下降。-psola source of Matlab, here to remind you that psola adjustment algorithm, it has great limitations, one is accurate tagging difficult to obtain, on the other hand, psola adjustment, that would cause more negative effects, including noise and machines, making the quality of synthesis will be decreased.
