  11. 11. Audio Production Tools and Techniques <ul><ul><li>The Underlying Principle </li></ul></ul><ul><ul><ul><li>Try to produce as good a signal as possible at each stage of the process. You can’t improve a poor signal in post -production, so get it right first time. </li></ul></ul></ul><ul><ul><li>The Golden Rule </li></ul></ul><ul><ul><ul><li>Monitor yourself. Listen critically to your output. </li></ul></ul></ul>
  12. 12. Recording Tools <ul><ul><li>PC Sound Card and Microphone </li></ul></ul><ul><ul><ul><li>(Headset recommended as it will position the mic correctly) </li></ul></ul></ul><ul><ul><ul><li>Use software such as Audacity to record (or Garageband on a Mac) </li></ul></ul></ul><ul><ul><li>OR Sony Minidisc </li></ul></ul><ul><ul><li>OR Solid state devices, e.g. M-Audio Microtrack 24/96 </li></ul></ul><ul><ul><li>OR Digital Dictaphone </li></ul></ul>

  14. 14. Editing Tools <ul><ul><li>Audacity (free) </li></ul></ul><ul><ul><ul><li>audacity.sourceforge.com </li></ul></ul></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>  </li></ul>

  16. 16. Important! <ul><li>Because MP3 is &quot;lossy&quot; you should only use it for your final version.   Always save intermediate drafts as an Audacity project file (AUP) or as a WAV. </li></ul><ul><li>  </li></ul><ul><li>Do not repeatedly save changes to an MP3 file - the quality disimproves each time you encode it. </li></ul><ul><li>  </li></ul><ul><li>(Like a photocopy of a photocopy) </li></ul><ul><li>  </li></ul><ul><li>Remember: </li></ul><ul><ul><li>Save your work as AUP or WAV </li></ul></ul><ul><ul><li>When the final version is ready, export it to MP3 </li></ul></ul>

  18. 18. Dynamics Processing (Loudness) <ul><ul><li>Sound equipment has a limited dynamic range. There is a maximum loudness. </li></ul></ul><ul><ul><li>If you exceed this (overmodulation) you lose signal information -> distortion </li></ul></ul><ul><ul><li>Keep inside the lines! ☺ </li></ul></ul>
  19. 19. Dynamics Processing (Quietness) <ul><ul><li>If a signal is too quiet, it is susceptible to noise </li></ul></ul><ul><ul><li>Signal-to-Noise Ratio </li></ul></ul>
