16SoundsUSB - 16 Synchronized Inputs USB (UAC2) Sound Card.

Authors

• Vincent-Philippe Rhéaume
• Dominic Létourneau
• Cédric Godin

We designed this sound card to work with our ODAS sound source localization, tracking and separation library. You can also have a look at the ODAS GUI application.

• Please contact us if you need an already assembled 16SoundsUSB kit.
