Advanced DSP Sound Quality Enhancement Effects

Sound Quality Enhancement Effects

The most important aspect of any audio program is how well it sounds. While sound quality can be extremely subjective, the general consensus from both reviewers and users alike is that the sound quality of DFX is exceptional. Read user reactions

Harmonic Fidelity Restoration

Adding Fidelity to your audio eliminates the "muffled" sound that is an artifact of the data compression algorithms used in Internet audio formats. DFX compensates for this loss of high frequency fidelity by carefully regenerating the missing high frequency harmonics in the audio. This harmonic restoration is performed using patent-pending technology that carefully synthesizes high frequency harmonics to replace the harmonics lost during the encoding process.

Ambience, Stereo Imaging

Adding Ambience to your audio compensates for the lost or diminished stereo depth that is the result of closely located speakers, poor listening environments, and sonic losses due to data compression of Internet audio formats. DFX compensates for the reduced stereo imaging and depth of PC audio by carefully regenerating the ambience and stereo depth. This same ambience processing has been used by Grammy winning engineers of artists such as Alanis Morissette and Ella Fitzgerald.

3D Surround Sound

Using the 3D Surround Sound component adds amazing depth and body to your audio, compensating for monitoring limitations and sonic losses due to data compression. With 3D Surround processing the sounds will surround you, virtually putting you inside the music! 3D Surround enhances the sound played on conventional 2-speaker systems and makes even small PC speaker systems sound larger and richer. It is also fully compatible with Surround Sound playback systems.


Using the HyperBass component adds deep, rich bass sound to your audio by compensating for the bass limitations of almost all PC-based audio systems and data-compressed audio formats. DFX does this by carefully regenerating the low frequency harmonics, thus increasing the perceived bass, but without exceeding the speakers physical limits, adding or changing speakers or amplifiers, and without increased power consumption. HyperBass greatly improves the bass performance of any sound system.

Dynamic Gain Boosting

Adding Dynamic Boost increases the perceived loudness of your audio while minimizing distortion levels, particularly when using Internet audio systems. By adding Dynamic Gain Boosting, your playback system will sound twice as loud without losing any punch on loud passages.

Typical PC-based multimedia playback systems and even home stereo playback systems suffer from limited dynamic range and headroom. Dynamic Boost compensates for this limited headroom by carefully processing the audio to increase the perceived loudness of the audio without altering the perceived dynamic range.

Speakers and Headphones Modes

Speakers and Headphones Optimization

The listening environment section allows you to quickly get optimized sound for your listening environment. Speaker mode optimizes your listening experience through speaker systems. Headphone mode optimizes your listening experience through headphones.

When in Headphone mode the audio is processed in such a way that the music sounds as if it is originating from a source in front of you rather than coming straight at your ears. This creates a much more pleasant and natural sound. It also reduces listener fatigue by eliminating the "in your head effect" of regular headphones.

Efficient Performance Using Minimal CPU

We believe that no matter how good the sound is, it is useless if it bogs down your entire computer. Therefore we make it a priority that DFX runs as efficiently as possible. DFX uses only your CPU to do its processing, and does not depend on any features of your sound card or PC sound system. Furthermore, DFX uses minimal CPU power to do its processing, and can easily run on a processor as slow as a 133MHz Pentium.

So whether you have basic or advanced sound setups, DFX will be fully compatible and complement your PC audio.
