Qualcomm presented this Wednesday (1) an evolution to its music sending technology via Bluetooth, named aptX Lossless. The company's goal is to take advantage of the growing market of streaming services with songs without loss of quality, such as Apple Music, Deezer and Tidal.

Currently you can choose a streaming service for music and listen to a song without loss of quality, also called Lossless. Tidal already offered this product, then Frenchman Deezer showed the world his catalog and then Apple Music did the same, with Spotify promising their answer to be released soon.

Even subscribing to any of these services, Bluetooth is still a very big limiter for those who want to listen to this type of music, in this quality. It needs to work with the correct codec, such as Qualcomm's aptX HD or Sony's LDAC. Now the American company known for Snapdragon processors has shown the world an evolution of its standard, called aptX Lossless.

Qualcomm's promise is to deliver audio in 16 bits and 44,1 kHz, reaching CD quality. The transmission theoretically reaches 1 mb/s, twice the aptX HD (576 kb/s) and more than the LDAC of the Sony, which reaches 990 kb/s on Hi-Res – far above the SBC used by Apple in its devices.

As the data rate is high in aptX Lossless, Qualcomm points out that its technology can reach a minimum of 140 kb/s. Looking at the best case, in a place without congested radio frequencies, the sound doesn't lose any data when it's sent to the headphones or speakers via Bluetooth.

aptX Lossless is not a new codec

As much as it sounds, the new aptX Lossless is not a new codec, created by Qualcomm. It is part of the aptX Adaptive technology, which identifies the source and destination of the sound, automatically realizing whether or not it can increase the transmission rate and thus activate the Lossless mode. This always depends on the device responsible for sending the Bluetooth signal, the version of the connection used and which codecs the speaker or headset can understand.

Qualcomm expects the first products compatible with the technology to appear on the market later this year. The first companies should be Xiaomi, Edifier and Master & Dynamic, in addition to Asus with the smartphone created by the company for Qualcomm itself.
