ZitatAften is a simple, open-source, A/52 (AC-3) audio encoder. Currently, it is a commandline application, but I plan to make a separate library eventually.
The name, Aften, is an acronym for:
A / Fifty-Two ENcoder
It is also Danish and Norwegian for 'evening'.This program started as a simple cutting-out of the AC3 encoder from FFmpeg, but then I reworked the structure of the encoder a bit. Most of the basic code is still the same though. Here are some of the things I've changed so far.
- Implemented my own wav reader and bitwise file writer
- Converted the fixed-point algorithms to floating-point
- Rearranged the methods and structures
- Added stereo rematrixing (mid/side)
- Added short block MDCT and block switching
- Added VBR encoding mode
Future Plans
- Variable bandwidth
- Channel coupling
Leider noch nicht getestet, scheint aber ein int. Projekt/Programm zu werden.
