2. Understanding of the waveformat Structure
The main difference between PCM and non-PCM is that the sound data is organized differently, which can be distinguished by the waveformat structure of the two. The following is a comparison of PCM and IMA-ADPCM:
The basic structure of wave is defined as follows:

I've written a validation class here that uses the file header to determine the file format. (also not completely secure, if the user forged the file header, can also be verified)
