Qualcomm Snapdragon QCC517x and QCC307x: BT sound in 24/96

Qualcomm has prepared Snapdragon Sound technologies for the OEM market. These are Bluetooth audio platforms, Qualcomm QCC517x and Qualcomm QCC307x, announced a year ago. They are equipped with dual-mode audio transmission, using LE Audio (Bluetooth Low Energy) technology in addition to conventional Bluetooth. Processor performance is doubled – and the power consumption of new products has not increased.

The novelties are promised flexible configuration with support for 16 bit / 44.1 kHz (“CD-quality”) via lossless Bluetooth, Hi-Res Bluetooth 24 bit / 96 kHz, as well as ultra-wideband telephony at a frequency of up to 32 kHz. Communication will be stable even with congested RF spectrum.

In addition to high quality lossless audio, the new chipsets have added a game mode with ultra-low latency – no more than 68ms, as well as support for in-game chat and a voice return channel. Headphones with Qualcomm Snapdragon Sound, at the same time, will be able to record a stereo signal – this will add creative possibilities to their owners and improve the quality of conversations. In addition, in the microscopic dimensions of a special hardware unit, adaptive noise reduction systems are located.
