(Pocket-lint) - Qualcomm has announced a variant of its aptX wireless codec that tin yet present 16-bit 44.1kHz CD-quality audio implicit Bluetooth. However, determination is simply a drawback - you volition request devices with the close hardware inside.

Dubbed aptX Lossless, the codec utilises aptX Adaptive technologies to alteration a watercourse to deed up to 1Mbit/s implicit Bluetooth - this allows the "lossless" audio to beryllium wirelessly transmitted and received arsenic agelong arsenic the RF conditions are close (ie. telephone and headphones are adjacent by and not excessively galore signals are conflicting).

The upshot is that the audio record received and played done compatible headphones (or talker system) volition beryllium identical to the 1 sent. There volition beryllium nary compression of note, nor volition determination beryllium immoderate audible deviation from the source.

This is simply a archetypal for Bluetooth. Even utilizing existing Qualcomm aptX technologies, determination has ever been a nonaccomplishment of audio explanation determination down the tube - albeit a fractional 1 successful immoderate cases.

The drawback is that aptX Lossless volition lone enactment connected devices built to incorporated caller Snapdragon Sound Technology. That means comparatively fewer existent devices volition beryllium compatible - particularly erstwhile it comes to headphones.
