Open source speech codec designed for communications quality speech between 450 and 3200 bit/s. The main application is low bandwidth HF/VHF digital radio.
*Summary* If the codec2 library is not installed in the default library/include path, other projects cannot properly include it via pkg-config. E.g. I get include errors in my application on...
Fixes #48 Properly define Cflags in pkg-config file. We need the additional path for non-standard installation paths of this library. We do not change the single include path to be...
Lets the advanced API programmer configure a OFDM raw data mode at init time, without having to modify libcodec2. It assumes the programmer understands how to configure the waveforms, use...
Started with `datac13`, reduced the payload to 40 bits, used a (128,56) code, with lowered code rate as only 40 payload data bits required, and increased Ts. Tcp a little...

This PR fixes the libasan-related crashes per #43. On x86_64, all tests now pass except for `test_demo_700d_python` (likely due to how libasan interacts with Python itself) and `test_clang_format` (Fedora's `clang-format`...
I see the following compiler warnings when compiling ezDV: ``` [1221/1349] Building C object _deps/codec2-build/src/CMakeFiles/codec2.dir/fmfsk.c.obj /Users/mooneer/ezDV/firmware/build/_deps/codec2-src/src/fmfsk.c: In function 'fmfsk_demod': /Users/mooneer/ezDV/firmware/build/_deps/codec2-src/src/fmfsk.c:186:9: warning: unused variable 'eye_max' [-Wunused-variable] 186 | float eye_max; |...
Currently several codebook files are generated at build time from .txt templates. This works well on Linux like systems, and means we "don't repeat ourselves) (DRY principal) but its a...
