If you like the waveform generators in Matlab, and you want to generat
'test' waveforms, then you could use Matlab to create your waveforms an
save them to files. Then in your C, C+ or C# code you just need to ope
the file and read out the samples. I have used this method in the past t
generate DTMF (telephone) tones for testing.
