The voice elements support multi-mic far-field voice capability with highly responsive voice activation and beamforming technologies. The software also incorporates echo-cancellation, noise suppression and 'barge-in' capability, supporting a reliable voice interface in loud or noisy environments even when users are far from the smart speaker.
Qualcomm's AllPlay multi-room audio technology supports whole-home audio music streaming. Speakers can be configured to play synchronized music across multiple rooms, different music in multiple speaker zones, and multi-channel wireless surround sound to multiple speakers in the same room. Consumers can play music from streaming music services including Hi-Res 32-bit/192kHz content, local music libraries on mobile phones, or DLNA media servers. Moreover, the new platform supports Qualcomm aptX HD audio technology, which is designed to deliver 24-bit high-definition wireless audio over Bluetooth.
Qualcomm also introduced in Shenzhen the CSRA68100, the company's next-generation Bluetooth audio platform for premium wireless speakers and headphones. This offers four times the DSP processing power of its predecessor, along with a powerful 32-bit dedicated developer application processor. In addition, the QCC3XXX is a new family of entry-level, flash-programmable audio SoC platforms for Bluetooth headsets and speakers.
For USB-C connected audio devices, Qualcomm launched its WHS9420 and WHS9410 single-chip USB audio SoC platforms. This takes advantage of the growing number of smartphones with USB-C ports for charging, which can also support high-quality audio. The two SoC options are designed to address both the entry level and mid to high end sections of the emerging market.
