Generate sinusoids with AWGN (additive white Gaussian noise)
Generate sinusoids with AWGN (additive white Gaussian noise)

Generate a sequence of 3 sinusoids (110, 220, 440Hz) each with
its own AWGN. Output the signal to a .wav file.

First draft, following Stack Overflow optimisation question:

TODO:
- Command Line Interface to accept any frequency and duration, and
  flexible number of signals (length of sequence), to generate sounds
  similarly to CSound.
