Lossless / Other Codecs / Re: HALAC (High Availability Lossless Audio Compression)
Last post by Hakan Abbas -Your first attempt at Rice improves more than a percent at compression and thirteen at speed? :-oYes, there is acceleration in my experiments in any case. Especially in low entropy data, the efficiency of Rice coding decreases.
(IIRC, FLAC computes the Rice parameter as the average residual. It is close to optimal.)
The JPEG-LS image format also uses Rice encoding. And calculates the parameter "k" retrospectively with a certain average. I calculated it in a similar way. Of course, the smaller the block size, the more accurate "k" values can be obtained. But in this case, we also have a lot of side information.
The adaptive method is better. I know you're doing a good job with my image compression studies. In this case, our work performance decreases significantly. For the most appropriate situation, this issue needs to be studied specifically.
