DeCoder is an open source audio plugin / Standalone application written in C++ and based on JUCE framework. It is a simple tool that, as its name implies, decodes a stereo audio signal into Mid-Side channel format, letting the user listen to each channel in isolation, as well as adjust their volume.
It is the first of a series of audio plugins and tools that are going to be released.
It is also my first actual experience regarding audio coding and software engineering in general, so any feedback would be highly appreciated!
DeCoder comes in the following formats:
- VST3
- AU
- Standalone (currently tested and built only for MacOS)
You can get DeCoder either by downloading its source code and building it directly on your machine, or by just downloading the pre-compiled binaries.
The project is configured using CMake and Juce's CMake API , so in order to build it you need to have a C++ compiler and CMake installed. According to Juce's CMake API Documentation, plugin projects like DeCoder require CMake 3.15 or above.

Clone the repo and navigate to it:
git clone https://github.com/GiorgosKoulouris/DeCoderPlugin.git cd path/to/repo -
Since JUCE library in already in the repo, you are all set to proceed to generating the project
# If you want a specific generator: cmake -G 'Your Generator' -B ./build # If you want your system's default generator cmake -B ./build -
Build the project
cmake --build build (--target DeCoder) (--config Release/Debug/...) # Or if you use Makefiles you can instead use cd build makeIf you generated the project using an IDE as a generator you can navigate to build folder and open the generated project located there.
When building DeCoder using makefiles, predefining CMAKE_BUILD_TYPE and using make command was the only solution to build Release config while reducing binary's size and avoiding having corrupted files generated.
For example, in my system that has makefiles as its default generator:
# Instead of:
cmake -B ./build
cmake --build build --target DeCoder --config Release
# Command chain would be:
cmake -B ./build -DCMAKE_BUILD_TYPE=Release
cd build/
make
Maybe that's an issue happening exclusively on my machine (MacOS 10.12), or i am just missing something from the cmake and/or make procedures. In any case, if anyone gets his hand on the project I would be grateful if I had his feedback on the issue.
Download links for the pre-compiled and ready-for-use binaries. Note that, at the moment, builds have been made only for MacOS systems. Building and testing on Windows will take place soon. Please read the System Requirements section below.

Unfortunately, Windows users have to be a bit more patient if they choose not to build DeCoder from source.
At the moment, DeCoder has been tested in a very limited number of systems, so I am not able to give specific information about this issue. To anyone that forks and builds the project in a Windows environment, or in any MacOS > 10.12, please consider sending some feedback back about it. I am going to update my system and cross-check different environments soon, but any info would be valuable.
Since DeCoder is my first dive into the waters of audio coding (and coding in general), I would be grateful if anyone that spots any errors or mulfunctions, or has any feature/add-on/improvement proposals contributed by either just visiting the discussion section or by creating a pull request.
