Push the Limits of Mobile Audio Quality

The Dirac approach to exceptional audio quality is unique. Rather than simply working within the limitations of conventional effects and EQs, we instead break the traditional boundaries that leave mobile audio sounding lifeless, and transform headphones and mobile devices into full-fledged entertainment centers that deliver superior, dynamic audio quality anywhere and everywhere.



From Hi-Fi & Automotive to Mobile

Even if you’ve never heard of Dirac, you’ve probably heard the difference our cutting-edge audio optimization technology makes at your favorite movie theater or cruising in a new Volvo, Bentley or BMW. Dirac technologies have been a staple in high-performance home audio, professional cinema and premium automotive markets for years, and we’re excited to bring our innovations to the mobile market.

Your Mobile Devices Can Offer More

Smartphones are more than just phones. They’re our private cinemas, our music libraries, our mobile gaming consoles, and so much more. Dirac explores the enormous potential of mobile device applications where superior audio is vital to the experience. We help turn movies on-the-go into immersive, panoramic sound experiences, and give mobile devices the power to optimize any sound system.



Headphone Optimization

Our headphone optimization solutions offer the purest possible sound and an immersive, panoramic sound stage that take the headphone listening experience far beyond what was previously thought possible.


Dirac HD Sound® delivers unique acoustic optimization custom-tailored for each specific headphone model, dramatically improving headphone performance.

Dirac Sensaround® widens and externalizes the soundstage of headphone playback, creating an immersive multi-dimensional listening experience unlike any other.


“ How good is it? I listened for about ten hours…compared the Apple EarPods with the Dirac app directly to the $1,100 Ultrasone Edition 8 on an iPhone 5. The optimized Apple EarPods are better ”

 – Ken Rockwell, famous audio reviewer



Speaker Optimization


Mobile devices are often our speakers on-the-go. But the size of these devices creates extreme challenges for engineers in creating superior sound quality. Instead, mobile audio is notoriously thin, distorted, and plagued by weak bass. We have developed tailored solutions to help engineers break through these limitations and drastically enhance the sound quality and listening experience on mobile devices.


By addressing the fundamental limitations of small and micro speakers, Dirac Power Sound® brings out their full potential, resulting in louder and higher-quality sound.

Dirac Panorama Sound® leverages mobile devices with two or more small speakers to create an extra wide soundstage and deliver exceptional sound quality.

Dirac Bass™ establishes a new standard in mobile audio by enabling mobile devices to reproduce deeper yet more transparent bass, on-par with much larger devices.


“ The difference between the Dirac HD Player engaged and not engaged is nothing short of amazing ”
