[Expand Summary]
Reverberation is a property of concert halls that greatly adds to the enjoyment of a musical performance. Sound waves propagate directly from the stage to the listener, and also reflect from the floor, walls, ceiling, and back wall of the stage to create myriad copies of the direct sound that are time-delayed and reduced in intensity. Learn how to model a reverberant environment using comb filters and all-pass filters, and how to implement these digital filters in LabVIEW to create an audio signal processor that can add reverberation an audio signal. In addition, learn how to place a virtual sound source in a stereo sound field using interaural intensity difference (IID) and interaural timing difference (ITD) localization cues. This course is part of the series "Musical Signal Processing with LabVIEW."

Learn about human perception of sound, including pitch and frequency, intensity and amplitude, harmonics, and tuning systems. The treatment of these concepts is oriented to the creation of music synthesis algorithms. A hands-on project investigates the specific choice of frequencies for the tuning system called "equal temperament," the most common tuning system for Western music. This course is part of the series "Musical Signal Processing with LabVIEW".
