Many thanks for your response, By Typically, I meant while exploring WAV, I
found that WAV is generally used for Uncompressed Audio, But it also

Regarding -> Dolby and Microsoft not defining a twocc or a GUID, Will it be
possible you can share some reference URL which I can read out and
understand this issue better
