我在看《Telecommunication Breakdown Consepts od Communication Transmitted via Software-Defined Radio》第七章数字滤波和离散傅立叶变换时遇到了对音频WAV文件进行频谱分析的实例，运行书附光盘的例程，出现了下错误，Google之，从官方寻找解决答案。

Problem Description:

Using the following code:
wavread('myfile.wav')
I receive the following error:
??? Error using ==> wavread Error using ==> wavread Incorrect chunk size information in WAV file.

Solution:

The WAV-file that you are trying to read is most likely constructed improperly. There are two numbers written into WAV-files that are related to the size of the file itself. If these numbers are incorrect, you will receive this error.

The following function can fix your WAV-file. However, you should create a backup copy of your file before running the following function since it modifies the file.

function wavchunksizefix( filename ) d = dir(filename); fileSize = d.bytes; fid=fopen(filename,'r+','l'); fseek(fid,4,-1); fwrite(fid,fileSize-8,'uint32'); fseek(fid,40,-1); fwrite(fid,fileSize-44,'uint32'); fclose(fid);
The function is run this way:

wavchunksizefix('filename.wav')
