Wireless audio SoC integrates AI processing

Airoha Technology’s AB1595 Bluetooth audio chip features a 6-core architecture and a built-in AI hardware accelerator. It consolidates functions typically spread across multiple chips into a single SoC and achieves Microsoft Teams Open Office certification.

The AB1595 uses AI algorithms and input from up to 10 microphones to improve speech clarity by reducing background noise. This collaboration allows it to accurately distinguish between the user’s voice and environmental sounds, achieving professional-grade speech quality. In noisy environments like offices and cafes, it enhances voice noise suppression from 10 dB up to 40 dB, optimizing speech quality and elevating consumer headsets to professional teleconference standards.

Real-time adaptive active noise cancellation (ANC) in the AB1595 boosts environmental noise attenuation across a wide frequency range. It detects the user’s wearing condition (e.g., fit or leakage) and adjusts compensation accordingly. Internal filters automatically adapt to both the fit and surrounding noise, balancing effective noise cancellation with comfort for a superior wearing and listening experience.

Airoha reports that the AB1595 has been adopted by customers, with products expected to be available in Q1 2025. A datasheet was not available at the time of this announcement. Contact Airoha Technology here.
