Qualcomm Introduces aptX Lossless Technology for Bluetooth Devices

North American technology Qualcomm is responsible for Snapdragon processors and the development of several new technologies and components for mobile devices. Indeed, technologies include, for example, Snapdragon Sound.

This Snapdragon Sound technology adds several improvements that are gradually introduced by the company, the last of which is the format aptX Lossless that promises CD quality, or comparable to this standard, for Bluetooth devices.

Snapdragon Sound technology now integrates aptX Lossless function

Description of the new aptX Lossless technology for Bluetooth devices.

As the name suggests, aptX Lossless technology allows for lossless audio streaming via Bluetooth, as long as the transmitter and receiver support it. That is, both the smartphone (example of transmitter) and Bluetooth headsets (example of receiver) must support it.

Once both parties support aptX Lossless technology it will then be possible to send / stream CD quality audio via Bluetooth. Finally, we will have a quality alternative to cable headphones and earphones for audio transmission.

It is, in fact, one of the biggest news for the audio industry since the popularization of the Bluetooth earphones and headphones. An increasingly popular solution since smartphones began to give up the audio port jack 3.5 mm.

Audio streaming via Bluetooth being lossy is a reality thanks to Qualcomm

The aptX Lossless functionality or standard not only guarantees better audio transmission quality via Bluetooth (wireless), but also has intelligent features. In fact, it is a standard that can reach a quality from 16-bit a 44,1 kHz.

As a general rule, however, if the strength / quality of the Bluetooth connection is not very good, the broadcast will adjust the baud rate to ensure that some audio reaches the receiver.

Thus, despite transmitting as a rule the 1 Mbit/s, if necessary, the signal is automatically reduced to just 140 Kbits/s in order to keep the connection stable for the user.

More specifically, the new aptX Lossless from Snapdragon Sound is an extension of the aptX Adaptive technology that is present in the best products and gadgets dedicated to wireless audio.

Note also that this technology operates a constant monitoring of signal input and output levels, adjusting as necessary to ensure the best possible quality and stability.

Hopefully, finally, the biggest snag of Bluetooth headphones and earphones – the quality of the audio stream – is resolved. This, of course, reminds us of the quality standard to be expected from a CD, without even daring to play in FLAC format.

Finally, the first audio products and solutions to support Qualcomm’s aptX Lossless standard will hit the market later this year.
