Nuvoton Technology Corporation announced that Beijing Twirling Inc. has launched a single-chip low-power voice module for immersive conferences application based on the Nuvoton ISD94100 series device.

The combination of ISD94100 low power consumption feature and the Beijing Twirling algorithm effectively ensure smooth and intelligent voice interaction capabilities, while reducing power consumption and production costs.

The module is an ideal fit for battery-powered devices, and the application can be extended to various small portable conference products such as Bluetooth speakers and Bluetooth headsets, further enriching the IoT category and addressing real user scenarios to provide a more efficient and convenient user experience.

This low-power voice module supports easy expansion to work other modules, for example, it can be used with Bluetooth and WiFi module and can be implemented with multiple data communication protocols through interfaces such as USB. Covering a variety of application scenarios such as smart home and smart car, to meet the needs of different fields.

The immersive voice module launched by Nuvoton Technology and Beijing Twirling Inc. supports three microphone array Ambisonic sound field acquisition. Ambisonic technology is widely used in immersive audio in recent years. It is the standard audio in VR / AR; it is also gradually supported in broadcasting, filming, and television industries, such as the MPEG-H agreement launched by the global standards organization. Some standards also have been defined in China Broadcasting System. Ambisonic has a powerful mode conversion function, which can simultaneously support traditional mono and dual-channel stereo sound transmission methods and can flexibly support all mainstream immersive audio formats such as 5.1 and 7.1 on the decoding side.

The core features of Beijing Twirling Inc. immersive audio modules provide the leading algorithm module solutions necessary for conference communication such as noise reduction and echo cancellation.

Besides, Beijing Twirling Inc. also launched a more integrated mini microphone array voice pickup module, with an extremely compact microphone layout and USB interface, which provides an excellent Turnkey for mini microphone voice devices such as mobile phone expansion voice pickup accessories.
