Dirac HD Player

Powerful sound improvement for your iPhone and iPod Touch

Thinking of buying expensive earphones? Try this first! The Dirac HD Player is an easy-to-use music player based on advanced technology that genuinely improves the sound from Apple's original iPhone and iPod Touch Earphones, EarPods and In-Ear Headphones. You can now listen to all your favorite music in your iTunes library with improved sound quality.    


The app is for everyone that wants better sound; no technical know-how is needed. Under the hood however, it uses state-of-the-art patented technology normally used in some of the world's best hifi, studio, cinema, and automotive sound systems.

It is impossible to design a perfect earphone solely with hardware components. Dirac's audio scientists have made precise acoustic measurements of the original iPhone earphones, allowing the design of a tailored digital software processor for the earphones based on the Dirac HD Sound® technology.

Like a pair of glasses improves the perception of poor eyesight, this technology improves and corrects the sound, so that it becomes cleaner and closer to a perfect sound reproduction. It has nothing to do with sound effects or graphic equalizers used in other apps.


No sound effect, but instead tailored to control the acoustic properties of the original iPhone earphones - the only way to achieve a genuine improvement that causes less listening fatigue.  

 Select your earphone model and hear the difference by switching ON/OFF.

•  Uses the same simple functionality that you are accustomed to with your iPhone, while the optimization runs in the background.

Natural sound with increased clarity in music and voices. Deepens the bass, removes resonances and acoustic problems related to sound reproduction.

  Very cost efficient and green alternative to buying new expensive earphones.

The app is also available in a free version, Dirac HD Player Lite, which has the same functionality as Dirac HD Player, except the following features:

- Import/create playlists
- Quick alphabetic search index of songs
- Shuffle and Repeat functions
- Support for Apple In-Ear Headphones
- Functionality to remember playing state between sessions, including playlist, track, point in time, shuffle state, and repeat state
