[music-dsp] Tone Generation in C

[Ralph Baertschi]

The most difficult part for a beginner is the system part. You must decide
whether
to put the tone in real-time on what kind of driver or to put it into a
sound-file.
Maybe try to use for these the portaudio-library.

To actually generate a tone is much more easy. For example a sin-tone of feq
f
at a sample rate sr you have the inner loop.

inc=2*Pi*f/sr;
for(int j=0;j<size;j++){
    out[j]=amplitude * sin(ph);
    ph+=inc;
    }
