我只是想使用wavwrite输出3个声音文件（.wav）。我在MATLAB中使用的数据使用soundsc播放声音很好，但由于某些原因，3个声音文件中有2个没有任何声音。
[data,Fs] = wavread('prj1.wav'); %Data file I read in
...%filtering with cascaded FIR filter
dataFiltered = filter(Hd,data); %applying filter to data
soundsc(dataFiltered,Fs) %plays perfectly
pause(6)
wavwrite(dataFiltered,Fs,'FIR_Cascade_Signal.wav'); %writes out perfectly, can play back fine.
我的问题出现在此之后：
...%Filter with different method, simple IIR filter if curious
dataFiltered2 = filter(Gd,data); %applying second type of filter
soundsc(dataFiltered2,Fs) %plays back fine, loud and clear
pause(6)
完美播放声音
wavwrite(dataFiltered2,Fs,'IIR_Cascade_Signal.wav');%Outputted file has NO SOUND
写出声音文件，但听不到任何声音
...%Filtering with notch filter. This uses dataFiltered2 as the first stage, and then filters out a 30Hz harmonic with the Notch filter
Yfilt_stage2 = filter(B,a,dataFiltered2);
soundsc(Yfilt_stage2,Fs); %Plays loud and clear, can hear everything
wavwrite(Yfilt_stage2,Fs,'Notch_Filtered_Signal.wav');%Again, no sound in output file
任何帮助将不胜感激！

这是我的电脑本身的问题。我在另一台计算机上尝试了我的代码并且工作正常。
