Analog Devices, Inc. (ADI) today introduced an embedded system for generating engine sound for electric (EV) and hybrid electric vehicles (HEV). The ADSP-BF706 digital signal processor and Electric Vehicle Warning Sound System (EVWSS) firmware enables automobile manufacturers in North America and other global regions to comply with future safety regulations mandating external engine sound for EVs and HEVs travelling at low speeds.

Download EVWSS firmware by submitting a request to http://www.analog.com/srf. Please specify EVWSS.2.0.0 in the additional comments field in the software request form.
The ADI solution includes a complete hardware and firmware reference design. It can be scaled for high performance with the ADSP-BF706 or entry level applications with the ADAU1450 Digital Audio Processor. The ADSP-BF706 can also be used to create in-cabin engine sound to contribute to an improved driving experience for vehicle owners. The ADSP-BF706 uses memory mapped quad SPI memory providing faster and simpler access to the stored audio files used to create the engine sound. It can access up to 24 WAV files simultaneously, compared to conventional products that can typically access only five.
ADI's Sigma Studio Integrated Development Environment (IDE) enables OEMs to graphically tune the audio sound when using the ADAU1450. This allows sound engineers with minimal programming experience to optimize audio performance while reducing development time. A new release of Sigma Studio supporting the ADSP-BF706 is due later this year. In addition, a low-cost CAN software stack runs on the ADSP-BF706 to help customers quickly build automotive-grade prototypes.
