Team J C Haxwell - Thereminimum Viable Product

This is a theremin [link], controlled using a Leap Motion [link].

The theremin consists of two files:

• A wrapper on the Leap Motion, outputting the palm position to the stdout as a tab-separated list of coordinates.
• An audio synthesizer, taking these co-ordinates and generating a sine wave of a given pitch.

Dependencies:

• Requires Leap Motion installed.

• Requires the shared objects from the Leap Motion SDK.

• Requires pyaudio (which requires portaudio)

• Uses select() to poll for command-line input, meaning this is Linux/MacOS only

What we got

• Non-blocking IO taking hand position and roll, converts to pitch and volume
• Plays a clap at max volume currently
• Crackles due to fast frequency change

What we want

• No crackle
• Two hands, two notes
• Better .wav sample playing on gesture
