* | [AT3P] Add GHA related bitstream codeDaniil Cherednik2024-07-3111-7/+2140
| | | | | | | | | | | | | | | | * borrow Huffman table from FFmpeg * code (with ut) to pack frequency part of GHA block * some related data structures * bitstrem modification to write correct GHA block * switch compile flag to use float data type
* | Merge branch 'master' into at3plus-devDaniil Cherednik2024-07-0916-40/+112

| * Allow to configure atracdenc to use float instead of doubleDaniil Cherednik2024-07-0913-34/+107
| | | | | | | | | | | | | | | | | | The default is double for hystorical reason. Actually no any reason to use double precision float point calculation for all processing. AT3P encoding will use float except places were we really need double precision. So this default will be changed to float in near future and this option will be removed.

* | Add Generalized Harmonic Analysis library in to the branchDaniil Cherednik2024-07-063-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | Why we start with GHA: * GHA is one of the most computation intencive part of the encoder. Probably we need to implement multuthreading processing here to achive good perfomance. If so it is better to make MT frendly design at the begining of development. * GHA is the most interesting part of AT3P. * GHA is the one of the first processing step. * We already have libgha (https://github.com/dcherednik/libgha) library which should be tested and used in real application )))

* Fix range to search proper bit allocationDaniil Cherednik2020-12-071-3/+3
| | | | In some cases we have quite small target number of bits so we unable to fit without reducing BFU number. But current algorithm starts reduce BFU only after succeful (from bit numbet perspctive) allocation. Which mean we must create zero allocation and only after that we restart allocation with reduced bfu number. The issue was the range to shift SNR was not enough to create zerro allocation in some cases.
