Synaptics unveiled its groundbreaking 12nm Tahiti Lite Audio DSP at CES 2025, delivering a major leap forward in audio technology. This next-generation chip is a significant upgrade from the previous 40nm Tahiti DSP, introducing advanced AI-driven features and remarkable power efficiency. The Tahiti Lite DSP is designed for headsets, monitors, and other audio devices, combining Environmental Noise Cancellation (ENC) with a compact design and longer battery life.
One of the key innovations is the addition of an onboard Neural Processing Unit (NPU), enabling the use of AI for sophisticated noise discrimination. This allows the DSP to isolate speech from ambient sounds with exceptional precision, making it ideal for applications like conference devices with support for up to 12 microphones. The Tahiti Lite DSP also includes a HiFi 5 engine and a proprietary MPU, offering enhanced processing power for real-time noise cancellation, speech enhancement, and sound optimization.
With its reduced size and improved power efficiency, the 12nm DSP supports smaller and lighter devices while extending battery life by up to 30% compared to its predecessor. This makes it perfect for portable and wearable audio solutions, including True Wireless Stereo (TWS) earbuds, Bluetooth-enabled devices, and wired headsets. Its hybrid adaptive noise cancellation technology features a low-latency engine that processes noise reduction in real time, with latency as low as 2-3 milliseconds.
The DSP introduces bone conduction technology, which uses accelerometers to detect vibrations in the user’s bones, distinguishing their voice from background noise for clearer communication. AI-driven voice activity detection further enhances performance by identifying speech probabilities in real time, allowing devices to focus on isolating the user’s voice while filtering out unwanted sounds.
Synaptics designed the Tahiti Lite DSP to be scalable and versatile, suitable for both battery-powered and USB-powered systems. It can adapt to various form factors, including integrated conferencing monitors, which eliminate the need for separate headsets. This makes it an attractive solution for office and remote work environments.
The 12nm Tahiti Lite platform represents a significant step forward in audio processing, combining AI-enhanced noise cancellation, extended battery life, and versatile design. These advancements promise to redefine the user experience in both consumer and professional audio markets. For more information, visit synaptics.com
