apt-X audio coding

Outstanding audio quality

apt-X technology is what wireless audio has been waiting for. With apt-X
audio coding, you can be assured of crisp, pure and full stereo sound.
It allows you to not only hear, but experience and feel the audio as it was
intended. Utilizing apt-X, 

Bluetooth

 can now offer wireless audio quality

that is indistinguishable from the highest quality wired connection.

Professional grade sound

Until now, apt-X has been the best-kept secret of the professional audio
industry. From major public broadcasters to film production studios, apt-X
is used throughout the world to transmit high quality digital audio from
A to Z in real-time. It was developed to meet the exacting standards of
musicians and audio engineers who love the exceptional dynamic range
and high fidelity it provides. 

Now available on selected consumer devices, the technology ensures that
music lovers everywhere can stream the rich listening experience that only
apt-X can deliver.

Revolutionizing Bluetooth

listening

Bluetooth

 technology has revolutionized our communications and

lifestyle by eliminating troublesome wires and letting us get on with life
“on the move”. Listening to a mobile phone conversation on a 

Bluetooth

earpiece sounds just fine but when it comes to delivering full stereo sound,
a little extra help is required. apt-X works within 

Bluetooth

 to deliver CD

quality audio, ensuring you are getting the most from your wireless
listening experience. 

In order to deliver two-channel digital sound within the 

Bluetooth

A2DP profile, audio compression is necessary. While traditional audio
compression technologies struggle to provide full-bandwidth, high-fidelity
audio over 

Bluetooth

, apt-X works to ensure you enjoy the fullest, richest

sound your music collection has to offer. 

apt-X legacy

If you have ever been to the movies or listened to the radio then chances
are you’ll already have heard apt-X in action. Over 20,000 radio stations
across the world and thousands of cutting-edge film studios rely on apt-X
for high quality audio delivery. 

The digital compression technology now known as apt-X was originally
developed in Queen’s University, Belfast, Northern Ireland. The technology
was first brought to market for radio automation applications to store CD
quality audio on computer hard drives for direct playout during radio
shows, hence automating the process of the disc jockey.

The acclaim the technology received lead to further research and
development and throughout the 1990s the technology was used by
Broadcast and Post-production studios worldwide to deliver high-fidelity,
low latency audio in situations where bandwidth was limited. The same
core principles that have earned apt-X worldwide acclaim in the Broadcast
and Post-Production markets make it the perfect solution for delivering
high quality audio on wireless devices. apt-X is leading the way in bringing
pro-audio quality to the discerning consumer.
