Qualcomm adds lossless audio via Bluetooth to its Snapdragon Sound system

The aptX Lossless technology of Qualcomm adds a new capability in Snapdragon Sound, designed to deliver lossless audio quality 16 bits and 44,1 kHz via Bluetooth.

The manufacturer Qualcomm has taken a system-level approach and optimized a number of core wireless and audio connectivity technologies, Included aptX Adaptive, that work together to self-detetetete and scale, designed to deliver lossless audio with CD quality.

"We are excited about the future of sound and are continually looking for ways to help our customers deliver new and exciting listening experiences.. Lossless audio means, mathematically, bit by bit, no loss of audio file. So far the bitrate needed to deliver this via Bluetooth has not been available.”, Explains James Chapman, Vp. and general manager of Qualcomm Technologies.

To help reliably deliver CD lossless audio quality via Bluetooth wireless technology, aptX Adaptive works together with technology Qualcomm Bluetooth High Speed Link to deliver the required sustainable data performance.

Designed to work together, these technologies provide speeds higher than 1 Mbit/s, but they are reduced without problems to 140 kbits/s in RF environments congested to reduce audio interruptions or failures.

"Sound quality is the most important buying factor across all audio devices., according to our survey State of Sound 2021 -Chapman- points out., which also shows a growing demand for higher quality audio streaming. More than half of respondents are looking for lossless or high-resolution audio quality, and a 64% notes that lossless audio quality will influence your decision to purchase wireless headphones.".

As the Qualcomm executive points out, “currently, lossless audio is only supported on client devices, as phones, PCs and tablets. By supporting lossless audio in current and next-generation hearing aids we offer 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 function”.

Features of aptX Lossless

• Supports LOSSless audio quality from CD 16 bits and 44,1 khz (the user can also select 24 bits with loss of 96 khz).
• Designed to scale to lossless audio CDs, based on Bluetooth link quality.
• Auto-detect to enable lossless audio when the source is lossless audio.
• Mathematically accurate, bit by bit.
• Bitrate: ~ 1 mbps.
