This program performs directional wave separation in discrete time Acoustic Pulse Reflectometry (APR) systems. The algorithm is based on the work of Louis et. al*. Inputs comprise the recordings from two microphones (pm1c, pm2c) that are axially spaced within a source-tube and the microphone spacing(shift), represented by the number of time samples necessary for a sound wave to travel between the two microphones. The outputs (pm2plus, pm2minus) are functions of the forwards and backwards traveling waves within the source-tube at microphone two.
