ARL STEP

STEP is a computer-controlled system for presentation and subjective evaluation of speech and audio signals that can run on any Windows PC. It was developed by a group of former Bell Laboratory acoustics and signal processing engineers. It is typically used in conjunction with an acoustically controlled listening environment, in which signals are presented via headphones or loudspeakers. The PC on which STEP is run must provide a video screen (e.g. LCD) for the listener to view the STEP control panel, a mouse for the listener to interact with the panel and an audio output card or device to interface to headphones or loudspeaker.
