Improving on aptX Adaptive

Qualcomm Presents Lossless Bluetooth format

Qualcomm's new aptX Lossless format is supposed to enable lossless audio transmission in CD quality with 16-bit 44.1 kHz via Bluetooth.

With Qualcomm's new technology, CD-quality audio files are supposed to be transferable wirelessly via Bluetooth. Qualcomm aptX Lossless is a further development of aptX Adaptive, as well as part of the "Snapdragon Sound" system for better Bluetooth sound, and is supposed to be able to transmit audio signals with 16-bit 44.1 kHz lossless via Bluetooth. According to Qualcomm, the new aptX version should automatically detect CD-quality audio files and switch the transmission to lossless if the RF conditions are suitable.

Furthermore, the new system is also said to be able to transmit music files in 24-bit 96kHz, but not lossless; listeners will be allowed to choose freely between the options. In addition, the maximum bit rate is said to be just over 1 Mbit/s, but it is also said to be dynamically scalable down to 140 kbit/s to avoid glitches in case of connection problems.

Qualcomm's new aptX Lossless is supposed to be available by the end of this year, but devices that support this technology also have to be developed first.
