USB Audio to I²S Audio Bridges

Our audio bridge solutions are designed to enable rapid development of audio accessories and provide turnkey features including digital audio streaming with a variety of CODECs.

No firmware development is required to use audio bridge solutions – all customization options are selected using a simple GUI configuration tool. These configuration options are then programmed directly into flash memory included in the device. By eliminating the need to develop a USB audio class device with an I2S CODEC interface from scratch, our audio bridge solutions greatly simplify development of audio accessories and shortens time to market.
