How aptX works
Qualcomm® aptX™ audio enables CD-like quality wireless audio because it solves the problem of sending the full music bandwidth over Bluetooth.
A Bluetooth connection is a bit like a data pipeline between devices. Because the pipeline has a maximum width, it can sometimes be difficult to flow large audio files through it.
aptX solves the problem of sending pure audio wirelessly over Bluetooth by reducing the size of the audio files so they can be squeezed through the wireless pipeline without affecting the sound quality.
Therefore, with aptX, you can experience CD-like quality audio whenever and wherever you choose.
The aptX codec has been the secret weapon of the music industry, public broadcasters and film studios for many years because of its ability to deliver CD-like quality
Outstanding Bluetooth® Stereo audio quality that faithfully reproduces the full audio bandwidth
Bluetooth® is limited by a maximum available bandwidth so it’s not always suitable for delivering high quality audio
Low audio coding delay that minimises latency and audio/video syncing issues
aptX has revolutionised the Bluetooth® Stereo listening experience by significantly reducing the bit rate without affecting audio quality or introducing latency issues
Backward compatibility that keeps the music flowing when aptX is unavailable
