Note: we still unable to handle situation with low frequency in subband which reuired much more samples for analysis. [AT3P] Update libgha version. 2025-05-15T21:51:50Z Daniil Cherednik dan.cherednik@gmail.com 2025-05-15T21:46:03Z urn:sha1:2a143471b0898dd8b6257ca69309a6f2b1c20bf3 This version doesn't use variable length arrays. It it better from compiler compatibility perspective and slightly faster.

Actualy we do not need such presition due to discrete values in the bitstream. New libgha version also does not perform multiple float to double conversion in the hot loop (although it can be not good from cache locality perspective). But it still gives speed up on modern CPUs. Minimal implementation of AT3P bitstream for residual signal. 2025-04-19T12:59:17Z Daniil Cherednik dan.cherednik@gmail.com 2025-04-19T12:07:51Z urn:sha1:e4de6009fbe23bb19a0f8135250ac2b514e0db3b * Write scale factor index, wordlen, codetable directly (without VLC) * Use huffman tables for mantisas * Some draft of the library to simplify bit allocation code * Tonal encoding teporary disabled * Allow c++14 Merge branch 'master' into at3plus-dev 2024-12-24T21:59:03Z Daniil Cherednik dan.cherednik@gmail.com 2024-12-24T21:59:03Z urn:sha1:bddbeb98b3db8d435de6b2d10269640121475538 [refactoring] Get rid of TFloat parameter.
