View this link for more informationManyEars requires a synchronous audio capture card. Although commercial audio acquisition cards are available, they are expensive, bulky, inefficient and too generic for the needs of ManyEars. Although functional, these cards do not meet the specific needs of mobile robotics and IntRoLab. The goal of 8 Sounds USB is to have an synchronous audio capture card with low power consumption and of a size similar to a credit card with 8 input channels and 2 output channels. The first iteration of the project is a prototype providing a synchronous audio capture card with wiring diagrams, circuit board, full documentation and source code available under Open Source Licenses. XMOS is our platform of choice to process the I2S codec data and USB transmission.
