How does aptX work?

Qualcomm aptX audio enables CD-quality wireless audio as it solves the problem of sending complete music data via Bluetooth.

A Bluetooth connection is similar to a "tubing" of data 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 wireless audio over Bluetooth by reducing the size of audio files so that they can be squeezed through the wireless "pipeline" without affecting sound quality.

Therefore, with aptX, you can experience audio quality similar to a CD or closer to the original recording quality.
