Qualcomm has announced aptX Lossless audio technology, a new addition to its aptX Bluetooth codec. Qualcomm says that the consumer demand for lossless audio is growing and streaming services are also making lossless music libraries available. Thus a new codec technique that could offer the best support is the need of the hour. The aptX Lossless offers support for CD lossless audio streaming for Bluetooth earbuds and headsets, which the company plans to make available to its partners later this year.
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.
The new aptX Lossless support is designed to deliver 16-bit 44.1kHz lossless audio quality over Bluetooth wireless technology. The codec will also let you manually switch to 24-bit 96kHz streaming mode, but by default, it will be set to 16-bit when it detects a lossless source.
Qualcomm touts that it has taken a “systems-level approach” in order to deliver CD-quality lossless audio. It has optimized a number of core wireless connectivity and audio technologies, including aptX Adaptive, its Bluetooth wireless technology to reach its goal.
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.
Below are the aptX Lossless features & specifications –
- Supports 44.1kHz, 16-bit CD lossless audio quality
- Designed to scale-up to CD lossless audio based on Bluetooth link quality
- User 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
It is worth mentioning that many companies and streaming services are jumping on the Hi-Res bandwagon already. From Apple releasing its own version of Lossless audio (ALAC) to Spotify promising to do similar later this year, we are seeing everything. But this big change is actually zilch to us since Bluetooth headphones can only stream lossy audio format. But, this might change soon, thanks to the now introduced aptX Lossless codec that will offer you a CD-quality audio experience.
