Apple announced lossless audio for Apple Music this year. However, the feature only works with wired earphones. For those who want to listen to lossless audio over Bluetooth, then you will be interested in Qualcomm’s new aptX Lossless audio technology which will provide lossless audio quality over Bluetooth.

Qualcomm says that aptX Lossless is a new technology under Snapdragon Sound which it announced in May. The new audio technology will bring CD-quality 16-bit 44.1kHz lossless audio quality over Bluetooth wireless technology, and it works by using aptX Adaptive in conjunction with Qualcomm Bluetooth High Speed Link technology to deliver the required sustainable data throughput. Even though they are designed to deliver rates beyond 1Mbit/s, Qualcomm states they are able to smoothly scale down to 140kbits/s even in congested RF environments to prevent glitches.

aptX lossless features and specifications

Supports 44.1kHz, 16-bit CD lossless audio quality
Designed to scale up to CD lossless audio based on Bluetooth link quality
Users can select between CD lossless audio 44.1kHz and 24-bit 96kHz lossy
Auto-detects to enable CD lossless audio when the source is lossless audio
Mathematically bit-for-bit exact
Bit-rate – ~1Mbps

Qualcomm’s aptX Lossless will be available in late 2021 via Bluetooth earbuds and headsets. This means that to enjoy the technology, you will have to purchase a new pair of headphones or earbuds that supports aptX Lossless. Of course, your phone will also have to support Snapdragon Sound which brings aptX Adaptive Audio technology that aptX Lossless makes use of. The Mi 11 Pro and Mi 11 Ultra are two phones with support for Snapdragon Sound.

Earlier today (28th July 2021), Xiaomi shared a new announcement regarding the latest firmware update for its FlipBuds Pro. With the new update, the TWS earbuds are now the first in the world to feature Qualcomm’s high end audio technology, Snapdragon Sound.

In a social media post, the Chinese tech giant revealed the new update and some of the key changes arriving to the earbuds as well. The firmware build is version 7.6.2.9 and officially brings Qualcomm Snapdragon Sound audio technology to the FlipBuds Pro. Through this, the earbuds will now receive three major features, which include a high definition audio transmission that can reach 48kHz to up to 96kHz. Furthermore, the calling capabilities have also been improved with ultra clear calls through 16kHz to 32kHz.

The final major upgrade is to the latency, with the device now offering an ultra low latency of just 89ms. This would prove great for people that use these wireless earphones while gaming on their smartphones. For those unaware, Qualcomm had launched the Snapdragon Sound audio technology back in March 2021. It arrives as an upgrade to the chipmaker’s existing aptX adaptive codec and offers a stronger anti interference and lower delays that is consistent with LDAC and LHDC. This technology even helps boost active noise cancellation performance and calling as well.

Qualcomm Snapdragon Sound wants to improve the audio performance of your devices

Qualcomm already has its hands in the audio technology space with its audio chipsets and codecs such as aptX. Now, it wants to take things a step further by improving the audio experience from devices with what it calls Snapdragon Sound.

The press release says Snapdragon Sound “is designed to deliver seamless, immersive audio experiences to devices by optimizing audio technologies and software across the entire chain”. It will combine Qualcomm’s existing technologies in audio, connectivity, and mobile, and then optimize them to work together to solve existing audio issues. The goal is sound with consistent quality, reliable connectivity, and low latency.

Qualcomm says Snapdragon Sound makes use of its aptX Adaptive Audio technology to deliver audiophile-quality music wirelessly from the phone to wireless earbuds or headsets. It also uses Qualcomm’s Aqstic audio codec to provide an equally impressive audio quality for those who prefer to listen directly from their mobile device. Snapdragon Sound will also provide a glitch-free listening experience when you are in a crowded place with lots of smart and connected devices. Glitches are frequent when in such areas and they are caused by interference from surrounding devices.

Snapdragon Sound won’t focus only on output sound but will also use existing Qualcomm technologies to improve input sound when you make voice and video calls. Features such as noise suppression and echo cancellation will make use of AI to provide crystal clear audio for calls. The audio solution will also use Qualcomm’s aptX Voice Audio to deliver better sound quality (greater voice clarity and speech intelligibility) when you use Bluetooth accessories.

Qualcomm boasts Snapdragon Sound will also be able to deliver latency as low as 89ms when using Bluetooth audio devices during gaming. It will be able to achieve this by utilizing the aptX Adaptive audio technology between the mobile device and Bluetooth accessory.

Snapdragon Sound badge

The press release says that products (earbuds, headphones, and mobile devices) will have a Snapdragon Sound badge so that consumers will be able to identify which products work best together. Qualcomm says that it will thoroughly test the performance of these devices in terms of latency, voice call quality, music quality, and robust connectivity.
