Our servers are available with a comprehensive hardware / software solution, which enables the dynamic acoustic correction of the audio chain including the listening room.

When a transducer (loudspeaker drive unit) emits a sound, that sound not only reaches your ear but also all the other elements in your listening room within fractions of a second. The sound is usually reflected several times in numerous directions, from walls, windows, the floor, the ceiling, furniture and so forth. It will be to some degree absorbed by carpets, curtains, upholstery and reflected from hard surfaces. All direct and indirect or reflected sounds will interfere with one another and mix with the direct sound arriving at the listening position from the speakers. Unlike recording studios or concert halls, your listening room was generally not designed specifically for the purpose of listening to music.

What about the process of active correction in the digital domain?
During the adjustment stage, the software emits a measurement signal through your loudspeaker tranducers. This signal sweeps the complete audio band, from extremely low to extremely high.

A supplied microphone determines the measurement signal response of the listening room. The software analyses the differences between the measurement sweep signal and the received one, so that it can generate a 'digital correction filter'. This filter is then used during playback to compensate for the computed defects.
 



The current maturity of these technologies implies that they take psycho-acoustic features into account and that the target curve is not necessarily a perfectly straight line. Indeed, it is generally a curve which gives the listening experience a natural and fluid feeling. That curve can be defined by the skilled user to take his own preferences into account or his listening ability (the example shown above is based on an audiogram showing a loss in high-pitched sounds).

This correction comes with a perfect adaptation of transducers. For each frequency, an impulse is issued by the system which measures the time required for the sound wave to reach the measurement microphone, this being done for each loudspeaker. Therafter, the registered time intervals are digitally adjusted, so that your listening benefits from a perfect adaptation of the loudspeaker transducers. The result is a better perceived focus of the various artists and instruments, as well as an enlarged and more stable sound stage.

However, some amount of passive correction of the room using acoustic absorbers or diffusion panels is also a good and complementary option and contribute towards better results with our room correction in the digital domain.
