Qualcomm recently released a Bluetooth audio codec called aptX Lossless, which claims to provide CD-quality sound quality over Bluetooth. According to the official introduction, the aptX Lossless Bluetooth audio codec can transmit CD-level sound quality (16-bit, 44.1kHz) audio through Bluetooth, and users’ wireless Bluetooth headsets can also listen to lossless sound quality.
However, aptX Lossless will compress the CD’s 1.4 Mbps bit rate to 1 Mbps. Qualcomm says they use fully lossless compression. With the release of aptX Lossless, the data rate of the aptX and aptX HD codecs will be greatly increased, and is expected to surpass the Sony LDAC’s 990kbps. In addition, aptX Lossless requires Snapdragon Sound audio technology to use, which means that older phones cannot be used.
aptX Lossless is expected to launch in 2022, and is expected to be available on devices that support Snapdragon Sound
