Qualcomm has simply unveiled aptX Lossless Audio, a brand new codec for lossless CD-quality audio that continues to be below the umbrella of its Snapdragon Sound expertise.


  • Qualcomm aptX Lossless Audio is now official
  • Helps lossless CD-quality audio (16-bit at a sampling price of 44.1 kHz) through Bluetooth
  • Accessible by the tip of 2021

Lossless audio, or lossless sound, is a brand new development in music streaming providers. Each Amazon Music Limitless and Apple Music now provide highly effective sound at no further cost to their prospects, and Spotify desires to comply with go well with as nicely. The issue with this, as we found in the course of the energetic dialog in regards to the Apple AirPods Max: We do not at all times profit from that stage of high quality through wi-fi headphones. That is the place Qualcomm intends to fill the hole with the introduction of aptX Lossless Audio.

Lossless CD high quality through Bluetooth

Just a few months in the past, Qualcomm launched its Snapdragon sound expertise, which has now been enhanced with the aptX Lossless Audio codec. This makes lossless audio codec that delivers CD-quality audio over Bluetooth out there to the lots. Earlier than you proceed any additional, how about trying out Ben’s complete article about all the pieces it is advisable know regarding Bluetooth codecs, AptX included?

In keeping with Qualcomm, AptX helps 16 bits at a sampling price of 44.1 kHz, which is the equal of lossless CD-quality audio. Relying on the Bluetooth connection or consumer request, that high quality is scaled. Because the consumer, you’ve gotten the selection of having fun with 24-bit audio at 96 kHz as nicely. If the connection high quality is poor, it is going to then be scaled all the way down to 140 kbit/s. Nonetheless, in an optimum scenario, just below 1 Mbit/s is feasible. Right here, one adapts through automated recognition which checks whether or not a supply provides loss-free audio indicators or not.

The codec is meant to activate lossless audio mechanically as quickly as a Lossless title is performed. Qualcomm lists the next options and specs for aptX Lossless in its current announcement:

  • Helps 44.1kHz, 16-bit CD lossless audio high quality
  • Scales to CD lossless audio high quality primarily based on the standard of the Bluetooth connection
  • Person can select between lossless CD audio (44.1 kHz) and lossy 24-bit audio (96 kHz)
  • Auto-detection to allow lossless CD audio when the supply is lossless audio
  • Mathematically bit-for-bit correct
  • Bit price – ~1Mbps

Availability from late 2021

The catch to all these figures and numbers is that this: our ears shall be unable to profit from this new codec till we acquire the suitable {hardware}. Nonetheless, it should not take too lengthy, as James Chapman (Vice President and Basic Supervisor, Qualcomm Applied sciences Worldwide, Ltd), defined:

With many main music streaming providers now providing in depth lossless music libraries and rising shopper demand for lossless audio, we’re happy to announce this new assist for lossless audio.We’re happy to announce this new assist for lossless CD audio streaming for Bluetooth headphones and headsets, which we plan to make out there to our prospects later this 12 months.

Will the primary merchandise that assist aptX Lossless be launched this 12 months? I do not assume so. Nonetheless, we do stay up for this case being remedied in the beginning of 2022 with one thing launched in your ears, and in wi-fi type, too.
