is there an adpcm decoder without reading the wav file?

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.

hello

have you solved your problem ?

have you tried to save your file under a more standard wav format (for example using Goldwavd freeware - quite powerful)

hello Mathieu NOE,

Thanks for your intersest,

I used FFmpeg Library through cmd..

hello

so have you tried to save the files under another format like the standard PCM signed 8 or 16 bits ?

hello Mathieu NOE,

Yes. Before using the wav files on MATLAB, I used FFmpeg Libaray to save the files under standard PCM 16 bits/sample.

hello Talal

so problem solved ?
