sirgfm/c_synth

Simple chiptune-ish synthesizer written in C.

c_synth

c_synth is a chiptune-ish software synthesizer. It takes a MML (actually a language based on MML) song as input and compiles it into the memory. The compiled buffer may then be played through whichever backend is desired, as long as it accepts samples in little endian and use either 16 or 8 bits samples.

Compiling and installing

All the following steps where also tested on Windows, using MinGW.

There are no dependencies to build the library. After cloning it, simply run:

$ sudo make install DEBUG=yes
$ sudo make install RELEASE=yes

The library will be installed on /usr/lib/c_synth and the headers on /usr/include/c_synth.

Testing and running

There are a few songs on the directory 'samples/'. They may be compiled and played using the examples on the directory 'tst/'.

Some tests uses SDL2 to actually play the compiled songs. On debian-based distros, that library may be installed by running:

$ sudo apt-get install libsdl2-dev

For other linux distros, look into your package manager or download the source and compile it manually.

To build the tests, run:

$ make tests

To play one of the songs:

./bin/Linux/tst_repeatSongSDL2 --frequency 44100 --mode 2chan-16 --file samples/sonic2-chemical.mml
