  • Acquire data from multiple audio input channels
  • Generate audio data for multiple audio output channels
  • Configure the sound card sampling rate and other settings
  • Analyze sound card data as it is being acquired
  • Trigger the start of your data acquisition
  • Easily switch sound cards with minimal changes to MATLAB code
