LOSSLESS BLUETOOTH INTRODUCED BY QUALCOMM TECHNOLOGIES

San Diego based Qualcomm Technologies International has introduced Qualcomm Bluetooth aptX Lossless audio technology.

Qualcomm Bluetooth aptX Lossless is a new capability of aptX Adaptive technology and a new feature of Qualcomm’s Snapdragon Sound™ Technology that is designed to deliver CD quality 16-bit 44.1kHz lossless audio quality over Bluetooth wireless.

Qualcomm Technologies say that they have taken a systems level approach and optimized a number of core wireless connectivity and audio technologies, including aptX Adaptive, which work together to auto detect and scale-up and are designed to deliver CD lossless audio when a user is listening to a lossless music file and the RF conditions are suitable.

LOSSLESS BLUETOOTH

“At Qualcomm Technologies we’re excited about the future of sound, and we’re continually looking for ways to help our customers deliver new and exciting listening experiences. Lossless audio means mathematically bit-for-bit exact, with no loss of the audio file and up to now the necessary bit rate to deliver this over Bluetooth has not been available. With many leading music streaming services now offering extensive lossless music libraries, and consumer demand for lossless audio growing, we’re pleased to announce this new support for CD lossless audio streaming for Bluetooth earbuds and headsets which we plan to make available to customers later this year,” said James Chapman, vice president and general manager, Qualcomm Technologies International, Ltd.

CD AUDIO QUALITY

To help deliver CD lossless audio quality reliably over Bluetooth wireless technology, aptX Adaptive works in conjunction with Qualcomm Bluetooth High Speed Link technology to help deliver the required sustainable data throughput. Designed to work seamlessly together, these technologies deliver rates beyond 1Mbit/s yet smoothly scale down to 140kbits/s in congested RF environments to minimize any audio dropouts or glitches for a consistent and reliable listening experience.

HIGH QUALITY STREAMING AUDIO

Qualcomm’s press release said: “Sound quality is the most critical purchase driver across all audio devices according to our 2021 State of Sound survey, which also shows increasing demand for higher quality streaming audio.  Over half of respondents are seeking either lossless or high-resolution audio quality, and a massive 64% saying that lossless audio quality is likely to influence their decision to purchase wireless earbuds,” Chapman continued. “Currently lossless audio is only supported on client devices such as phones, PCs and tablets. By supporting lossless audio on next-gen earbuds and headphones, we’re providing our customers another way to deliver sound the way the artist intended, as well as a significant opportunity to differentiate and be among the first to develop products with this feature.”
