This reference design, featuring the TLV320AIC3256 audio codec, is a fully-functional USB powered streaming audio platform that allows external audio sources to be connected to the USB port of a PC or laptop. User control is provided via a powerful, easy-to-use Windows-based GUI.
Software development for the TLV320AIC3256 is supported through TI's comprehensive PurePath™ Studio Development Environment. A powerful, easy-to-use tool designed specifically to simplify software development on the TLV320AIC3xxx miniDSP audio platform. The Graphical Development Environment consists of a library of common audio functions that can be dragged-and-dropped into an audio signal flow and graphically connected together. The DSP code can then be assembled from the graphical signal flow with the click of a mouse.
The USB Audio Reference Design is operational with one USB cable connection to a PC. The USB connection provides power, control, and streaming audio data to the EVM for reduced setup and configuration.
