Use float. 2024-12-21T15:30:07Z Daniil Cherednik dan.cherednik@gmail.com 2024-12-20T21:31:20Z urn:sha1:74d6e04c21bddd435bd74c34dbe027b883772a76 [refactoring] Get rid of inheritance from data. 2024-12-12T22:52:19Z Daniil Cherednik dan.cherednik@gmail.com 2024-12-12T22:26:24Z urn:sha1:39986e653def9d1130235c1cd6a38c3251bb6d79 Tiny quality improvements for ATRAC3 compatible mode: 2024-12-01T21:28:26Z Daniil Cherednik dan.cherednik@gmail.com 2024-11-30T12:32:34Z urn:sha1:2ca3d7fb3cfdc0b311bb20426d53782910dee64e * Use adaptive ATH, but efficient is limited due to qmf aliasing. * Use loudness instead of energy to split M/S frame size. Attempt to use adaptive ATH for ATRAC1 2024-10-10T22:07:48Z Daniil Cherednik dan.cherednik@gmail.com 2024-10-10T22:07:48Z urn:sha1:57ba306db046601b96b5a1943e63574a37c5e96c Bring some ATH related code from musepack project 2024-08-02T22:52:04Z Daniil Cherednik dan.cherednik@gmail.com 2024-08-02T22:52:04Z urn:sha1:a18796c67f26df138601a0e6061daeed03808a29 Motivations: - We need some psychoacoustic model to apply it in the AT3P during GHA. The idea is try to use ATH along with some tonality measurement to determine whether GHA gives profit or just penalty due to non effitient GHA bit encoding. - We can try to improve AT1 and AT3 quality applying ATH Support for MS Windows platform 2019-05-14T22:14:42Z Daniil Cherednik dan.cherednik@gmail.com 2019-05-14T22:14:42Z urn:sha1:ed9629395ce9696164c1d617d573a47982e82169 - VS build (2017 tested) - Media Foundation Framework support to read/write pcm data (instead of libsndfile) Set LGPL v2.1 license 2017-02-12T13:14:56Z Daniil Cherednik dan.cherednik@gmail.com 2017-02-12T13:14:56Z urn:sha1:3740b709a39e4a1eca7a5fbd598e8554944ce0e7 Dirty implementation of atrac3 encoder: 2016-09-02T18:21:28Z Daniil Cherednik dan.cherednik@gmail.com 2016-03-13T06:49:33Z urn:sha1:cfaa2cd39b7256a868a4f5cd83aac207df6bd1b3 - no JS mode - constant quantiser for tonal components - gain controll implemented but produces some artifacts with real signals. - etc...
