The first release should contain these key features:

• Ability to set an audio library (allow recursive file checking?)
• Ability to play and visualize audio files (MP3)
• Ability to create loops
• Ability to crop audio files and save as new MP3's (existing or new audio library)
• Ability to cache settings
• Hook up prototype version of equalizer
• Ability to alter playback speed
  • python would use your audio player, holwer.js uses a web player. HTML5 seems to be the main way people modify playback on the web (more desirable/portable), but it has limitations and may not interface with other playback modifications as well.
• Decent looking GUI
  • We will eventually make it look gorgeous, but not sure that is necessary for first release
• Passing R CMD Check
  • Not sure if we will have tests for first release, but it would be nice to (and look a lot better/more trustworthy)
