What you will need to build

build system

The system uses make and a Makefile for the most of the processing in order to compile the binary but we use the conditional compilation of the pre-processor for printing in different formats… When you need to create a audio file there is a problem. Printing the time array in the first column works when plotting but not when the output should be a mono channel (for monophonic oscillators).

For that matter the flag ‘-DMUSIC’ living in the main.c file will determine if the output will be for graph representation (commented out) or would be a single column to use it with the python script to produce a .bin file. Then ffmpeg will happily make a output.wav file in the root directory of the project.

compile commands

To build the binary application which lives in the ./bin/ directory.

cd root/proj/dir
make clean && make

To build the binary output.bin file and use ffmpeg for the creation of the sound file which lives in the root directory.

cd root/proj/dir
make clean && make
./bin/test > output.txt
make music

Changing the names of files…

This should be obvious but modifying the name “output.txt” will give an error because skill issues (bored to find out how to use the file name as input).

**modify** the Makefile if you want other naming scheme.
