Yes, now it is not easy to hear the difference. I found one track on
Marantz demo cd where quantization noise is noticeable without ADPCM.
About bit allocation. Current algorithm fails (av_assert0(used_abits !=
USED_1ABITS)) even with 250-320kbps on some tracks - probably I can fix it.
Thank you.

Tiny fix: missed inline attr.

All notices were fixed. Also I found issue with uninitialized subband
buffer - fixed. New patch attached.

Hi.
This patch introduces initial implementation of subband ADPCM encoding for
DCA codec.
Some results:
sample:
https://yadi.sk/d/B_3sVskM3HZiWK - original
https://yadi.sk/d/7CK47Nt63HZiWf - without adpcm
https://yadi.sk/d/25q1JDV93HZiWq - with adpcm
