Overview

The Audio Mini is an audio processing cape designed for the Altera DE-10 Nano. This cape contains an AD1939 audio codec that is used to sample audio from the line input and play back audio to the headphone output. The sampled audio is passed to a Cyclone V FPGA on the DE-10 Nano where the data can be processed. This platform is ideally suited for educational use as it is relatively low-cost and can be used in conjunction with Mathworks Simulink and FPGA Open Speech Tools’ code generation tool to rapidly create effects. This workflow also makes the Audio Mini an excellent tool for developers who wish to create prototype algorithms for devices such as hearing aids or sound effects processors.
