Description: 非常简单的浮点 FFT 运算。
没有加窗。没有任何多余的东西。点数任意设。
这个程序已经直接在BC下调试通过。
12.txt是GOLDWAVE将1KHz的保存为文本文件。
左右声到各一个,所以在文件中有N多个两个一样的值。
所以C在打开文件后要取两次,丢掉其中一个。
FFTRESU.TXT是FFT后的结果。-Float point FFT C program Very easy.
No window.Any points.

Description: AAC编码器的matlab实现,可以导出AAC编码中间过程的系数-Usage:
Take a wav file (44100, Mono) and name it as original_input.wav or change name in main_aacencoder.m.
1. Open the file main_aacencoder.m to encode original_input.wav in ADTS AAC format.
2. Run the file.
3. Check the output encoded_input.aac
4. Download FAADv2 decoder from http://www.rarewares.org/aac-decoders.php, or sourceforge.net/projects/
5. Place the windows binary faad.exe in this folder. To decode this encoded AAC file run decode.bat, it uses faad.exe to decode.
6. Open the file encoded_input.wav. Enjoy !!
7. Use Adobe Audition/GoldWave to open wav files, or use any media player for the same.

Description: (1)录制语音文件
利用GoldWave或NGwave录音软件录制单字发音语音文件,以wav音频格式保存,共录制两组,一组用于计算参考模板,另一组作为测试模板用于语音识别。
录制语音时,为了能够在主程序中循环读入语音文件,文件名采用数字顺序命名。记录语音文件以及所对应的发音。记于表3中。
另外,录制语音时,注意调整合适的Mic音量,避免语音波形幅度过小,难于同噪声区分开。同时也要避免波形幅度过大,造成波形失真。
(2)调试端点检测程序
结合流程图读懂Matlab程序,先单独调试,记录并观察测试结果。
原始语音中检测出起始和终止端点后,用plot( )函数绘制原始语音文件波形图,检测得到的端点之间的语音波形图。对比图形,分析检测结果是否满意。
(3)调试DTW主程序
结合图3.2所示流程图修改和调试Matlab程序,加入DTW实验系统工具箱文件,调试运行程序。
(4)运行和测试系统
先把录制好的声音文件(自己录制的和其他同学录制的)制作成2组声音文件,再准备两个测试音文件。
