I have many wav files on my computer, and when reading them using the function audioread, I get the followong error:

[File could not be read due to an unexpected error. Reason: Error in WAV/W64/RF64/ file. Malformed 'fmt' chunck]

Note that all these wav files characterized by 4 bits per sample as bit depth, 32 kbps as bit rate, and 8 KHz as sampling rate. Only these files holding these 3 characteristics can not be read using the audioread function.

I think that these files are compressed with adpcm method, so is there a way to decode or decompress them without the need to use the audioread function?

thanks in advance.
