AKM Starts Sampling AK7749 DSP-Integrated CODEC for In-Vehicle Voice Applications

Asahi Kasei Microdevices Corporation (AKM) has developed and started the release of samples of the AK7749, an in-vehicle DSP-integrated CODEC with an automatic mode switching function to support voice applications, and a full range of digital and analog input/output interfaces. The AK7749 is a RAM based, highly integrated, programmable digital signal processor, with 4 channel ADCs, 2 channel DACs, a MIC gain amplifier, a line-out amplifier, 4 channel SRCs, and digital audio I/F, all in a space saving small 48-pin QFN package.

In the run-up to the AES 2022 International Conference on Automotive Audio taking place in Dearborn, Michigan [https://audioproducteducationinstitute.org/aes-2022-international-automotive-audio-conference/] the AES Audio Product Education Institute (APEI) is promoting a special webinar event focused on the future of automotive audio workflows. In this session, Roger Shively will lead a discussion with John Whitecar (DSP Concepts), Evan Bunner, and Matt Marchese (Tymphany) on the evolution of automotive audio systems, technology, and implementations.
