The Input Devices and Music Interaction Laboratory (IDMIL) DigitalAudio Workbench (DAWb) is a web application designed for experimentation with key concepts in digital audio theory with interactive visualizations of each stage of the analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC) processes. By experimenting with the settings of the simulation, numerous key concepts in digital signal theory can be illustrated, such as aliasing, quantization, critical sampling, anti-aliasing filtering and dithering. The interactive interface allows the simulation to be explored freely; users can modify parameters and examine the resulting signals visually through numerous graphs or listen to the resulting signals. The workbench has been extensively used during the 200-level Introduction to Digital Audio course at McGill University in Fall 2020.
