Services->WAVto320MP3 -script (Automator/Bash)

Was asked to create a simple Service that uses LAME to encode WAVs (or AIFFs, too, I guess) into 320 MP3s, using Automator.

Here’s the solution for those of you that don’t feel like going through the rigmarole that I just did — of trying a few methods and then finding 3 methods online that no longer work and then finding the fourth method that did work.

Objective: A Service, available in Finder, that takes your selected files and encodes them as MP3s at V0 320kbps, and places them in the folder.

• Start up Automator
• Select New Service
• “Service receives selected” “Audio files” in “Finder.app”
• Add a “Run Shell Script”
• Switch Pass input to “as arguments”
• input all this:

for f in “$@”
do
/usr/local/bin/lame -q 0 -b 320 “$f”
done

• Add Display Notification and write according to your needs, for instance, something like:
• Title: “WAV to 320 MP3″
• Message: “Conversion complete.”
• Click Save and choose your easy-to-remember filename such as 320mp3
• Go into Finder, select a few WAVs and right-click (ctrl-click) on them, select Services->320mp3
• Wait
• Celebrate
