Podcasting from Mac OS X - A Recipe

Ingredients:
1 - Macintosh OS X computer
1 - Griffin iMic (for machines without a line-in input)
1 - Microphone
1 - Set of earphones or headphones
1 - copy each of the following pieces of software installed:
Audacity
Soundflower
Soundflowerbed
LineIn
Sound Source

Directions:

  1. Open Audacity. Using its preferences, set sound input source to Soundflower (2 ch).
  2. Use SoundSource (headphone icon in the menu bar) to set "Output" to Soundflower (2 ch). Set "System" to built-in audio if not already set there.
  3. Open LineIn and set it to input from your microphone source (Built-in audio if using internal microphone or a line-in, the USB sound source if using an iMic or USB microphone) and output to Soundflower (2 ch). If you make any changes, click the checkbox to disable and re-enable to make them effective.
  4. Open Soundflowerbed. Set the Soundflower 2 Ch monitor to "Built-in Audio." At this point, you should be able to hear in your headphones the sound from the microphone.
  5. Open any media player programs you will be using - iTunes, Quicktime, etc. For any player program that was open before you began and for which you are not hearing output, close and restart it. Some programs (like Quicktime) only set their outputs at startup. iTunes, on the other hand, happily changes outputs while it is still running.
  6. Begin recording in Audacity. You should be able to see the waveforms of the recorded sound from your microphone, et al. Try playing sound from other sources. You should both see them recording in Audacity and hear them in your headphones.
  7. At this point, you are set up. Let your creativity be your guide. When done recording, always save your audio files before editing. Audacity is not crash free, and you don't want to lose your copy of the original by editing before you save it (says the voice of experience.)
  8. Shutting down is not to order dependent. Be sure to use SoundSource to set sources back to their proper locations.
