30 Years of Qualcomm® aptX™

Our history delivering high quality digital sound.

Late 1980’s

aptX is born

The original aptX audio codec originated as the result of research at Queen’s University Belfast. This innovative work specifically focused on audio compression techniques to deliver audio for wideband stereo audio applications in the music, film, radio-broadcast, and post-production sectors.

Early 1990's

Film debut

DTS and Steven Spielberg collaborated to use aptX to record audio for 5.1 digital playback for films including Jurassic Park, Schindler’s List and Saving Private Ryan.

Music and post-production: aptX standard for ISDN

High quality and low latency, aptX was the ideal technology for audio transmission over ISDN lines, becoming the de facto standard for music and post-production studios and was used for mix approvals and voice overs.

1990s & 2000s

Radio broadcast

Over 30,000 radio stations worldwide use aptX to deliver high quality audio for applications including studio-to-transmitter links and outside broadcast.


Sennheiser launch first aptX enabled headset

In launching the first ever Bluetooth headset with aptX, Sennheiser was the first to bring consistent, high quality audio to wireless consumer electronics. With aptX, Bluetooth-enabled devices overcome historic barriers with Bluetooth.


Launch of wireless HD audio - aptX HD

In 2016, we launched Qualcomm® aptX™ HD, a next-generation audio coding technology designed to support advanced, high definition wireless sound quality, barely distinguishable from high resolution audio.


Launch of Qualcomm low power premium Bluetooth systems on a chip (SoCs)

Redefining the future of hearables, these wireless earbuds and hearables are small, light and ultra-low power, allowing listeners to experience longer battery life and playback time.
They integrate biometric sensors, voice interaction, voice assistant services, Qualcomm TrueWireless™ Stereo and aptX for high-quality music streaming.


Replacing the wire – launch of aptX Adaptive

Our latest audio codec is designed to bring dynamic, next-generation, premium wireless audio experiences for gaming, video and music. Dynamically adjusts performance to deliver exceptional audio whether you’re playing games or listening to a song.
