Voler developed a prototype for an audio system with advanced digital signal processing for acoustic echo cancellation, ambient noise cancellation and equalization to maximize performance. The system gets its input through an analog front end that filters, amplifies, and powers microphones.  It can also drive multiple speakers through high quality, high performance DACs.  In addition, the unit has digital PCM inputs and outputs to connect to newer digital sources.  The whole system is configurable through a custom cloud interface that allows rapid configuration and deployment.
