Elements of acoustics/psychoacoustics and programming

Acoustics and Psychoacoustics

• Sound waves, sound parameters; sampling rate, the Nyquist criterion
  
• Overtones and partials; wave shapes; Fourier analysis, additive synthesis.
  
• Tuning and scales
  
• Beats, critical band, consonance and dissonance; difference tones
  
• Rameau's harmony
  
• Helmholtz and the perception of timbre.
  
• Power and loudness; Fletcher-Munson curves; dB, phons, and sones
  
  Take home Quiz 1: acoustics - due 9/19
• About computers
  • representation of numbers; integers and floats
  • Operating Systems languages; compilers:
  • representation of sound waves; sampling rate, formats
  • Object-oriented programming and C++
    
• UNIX/Linux
  • logins, passwords;
  • directories and files;
  • basic UNIX commands (ls, cat, more, cd, mkdir, rm, rmdir, etc.), sftp, ssh, putty, winscp
  • available editors (gtom, emacs, edit, vi/vim)
  • Audacity
