aptX Lossless: New Qualcomm technologies set to provide ‘CD-quality audio’ through wireless headphones

Lossless music has had a excellent 2021 so far following Apple’s move to join in on larger-high-quality streaming and Amazon’s selection to not charge an added premium. But the most important challenge for lossless audio is playing it wirelessly on earbuds and wireless headphones.

Now, Qualcomm thinks it has solved the difficulty with its aptX Lossless, a component of the Snapdragon Sound programme that the organization announced earlier this year.

Technically an extension of aptX Adaptive, the aptX Lossless can stream more than Bluetooth CD-high-quality, 16-bit/44.1kHz lossless audio, Qualcomm mentioned. The very first devices featuring the new technologies are anticipated to come out early next year. Snapdragon Sound utilizes the complete hardware chain to optimise efficiency, which implies each the Android phone and the headphones or earbuds have to have to be compatible with the technologies.

According to Qualcomm, the Snapdragon Sound will automatically choose up a lossless audio supply and play it at a great deal larger information prices than probable with the preceding aptX HD. The organization has also outdone Sony’s LDAC in bandwidth terms — the aptX Lossless can hit 1Mbps, though the LDAC has the bandwidth capped at 990kbps.

Qualcomm is nevertheless applying some compression the sample price in CD-high-quality music normally hovers about 1.4Mbps. However, Qualcomm’s lossless compression reproduces mathematically bit-for-bit precise audio.

The technologies will also dynamically scale the bit price down to as low as 140kbps in environments of wireless congestion to provide the ideal-high-quality audio efficiency based on the high-quality of connection. Sony’s LDAC technologies, when its bit price is pushed to the limit, might struggle in the genuine world. As a outcome, it is no surprise that Qualcomm has supplied a answer to make the knowledge smoother.

CD high-quality is the aptX Lossless’ limit, nevertheless. Hi-resolution audio tracks can nevertheless be played, but that may possibly finish up with lossy streaming.
