What is aptX - Definition?

The aptX is the digital audio data reduction technology owned by Qualcomm. This Audio codec allows real-time streaming of high quality stereo audio over a Bluetooth A2DP connection.

Bluetooth is limited by a maximum available bandwidth. So, it is by default not suitable for delivering CD-like audio quality. The aptX has revolutionised the Bluetooth audio experience. The best thing is the backward compatibility. So, music streaming will work normally if aptX is not available.

It must be incorporated in both the source and the accessory device for work. Having it in only one wouldn't work but it is backward compatible. So, it will still be streaming audio but without the benefit from the technology. It enhances the wireless sound quality of smartphones, speakers, soundbars, headphones and tablets. There are more than 430 consumer electronics brands using aptX.

It is used in consumer and automotive wireless audio applications. The aptX algorithm was developed in the 1980s by Dr. Stephen Smyth and the commercial introduction began in 1990. Initially, it was used in global radio broadcast industry for delivering digital sound with near-CD quality. In 2009 the aptX audio codec began to bring high quality audio to wireless consumer electronics applications
