I can assume based on the below excerpts from ac3enc.c that the AC3 encoder defaults to None for the Dynamic Range Compression profile specified on page 10 in Dolby's Metadata Guide:
659 /* assumptions:
* no dynamic range codes
* bit allocation parameters do not change between blocks
* no delta bit allocation
* no skipped data
* no auxiliary data
* no E-AC-3 metadata
1402 /* dynamic range codes */
1403 put_bits(&s->pb, 1, 0);
If this is not the case could someone explain the above code?
Is there a way to apply specific DRC profiles per the Metadata guide?
