Re: [FFmpeg-devel] [PATCH] avcodec/dcaenc: Initial implementation of ADPCM encoding for DCA encoder

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

All notices were fixed. Also I found issue with uninitialized subband buffer - fixed. New patch attached. On Wed, May 3, 2017 at 7:49 AM, Rostislav Pehlivanov wrote: > On 2 May 2017 at 22:53, Даниил Чередник wrote: > > > Hi. > > > > This patch

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 chirp tone:
