Audacity Things

UPDATE: And no sooner to I post this micro-step-by-step than does O'Reilly come out with a huge article giving all the juicy details of audio conversion. Funny they don't mention any of the free programs like Audacity, though.

Continuing my tutorials series... I posted this on Ex-Gay Watch because they needed some help converting enormous AIFF files to mono mp3's for internet distribution. Might be useful if you're recording conversations or podcasting.

Audacity us a free, open-source, Windows/Mac/Linuz program for optimizing and mixing audio.
  1. CTRL+Click on your AIFF file and choose Open With->Audacity.
  2. Go to Preferences->File Formats
  3. Adjust the "bit rate" under "MP3 Export Setup" to something small, to reduce filesize. Voice seems to become unrecognizable below 64, so I reccomend not going lower than that.
  4. Hit "Okay
  5. Go to File->Export as MP3
  6. Save your mp3 file.
You're done!

The only kink in this might be that you do not have the LAME mp3 encoder installed. A tutorial for installing LAME is located here.

Alternatively, open up Garageband, make a new Real Instrument track, drag your AIFF file onto it, and hit "export to iTunes." That will export a 192kbps mp3 file into your itunes, from which you can publish or do what you like.

Finally, you could use Audio Hijack with the pro version. It might be overkill, but it's only $16 if you already own Audio Hijack ($32 total), and it does mp3 exports and allows you to pick quality and other settings to reduce filesizes.
