AFMT_AC3 sample format

Dolby Digital (AC3) sample format


The AC3 sample format is designed by Dolby and it's commonly used on DVD video disks and in digital satellite/cable/terrestrial TV transmissions. Please look at the documentation available on Dolby's web site for more information.

The AC3 format is not linear and requires special encoding and decoding algorithm that can be licensed from Dolby. This is beyond the scope of this document.

The AFMT_AC3 format requires significantly different handling than most other sample formats known by OSS.
