to high resolution musical performance in any room.

EIKON Space-Time Room Optimization

 The IMAGE1 with it's wavelet analysis based “Space-Time Room Optimization”  resolves room generated bass imbalance and image blurring. Able to see the problems build up in your room millisecond by millisecond and then correct with powerful algorithms addressing both amplitude and time, Eikon’s IMAGE1 can see and correct energy build up in both space and time and for the first time resolve the final barrier to quality sound in your room.

Typical System Without Correction ​​

Frequency Response Shows Significant Room Interference

Room Interference In The Time Domain

The local variations seen in the power response diagram are due to room modes and reflections from the rooms walls, floor, and ceiling. They resemble a typical time gated listening room frequency response measurement.
This image shows the same recording as the power response map from the left but utilizes a third measurment, time, with the sound pressure level color-coded according to the bar on the right. In a perfect scenario, the graph would show the darkest red in a straight line opening towards the left as the ridge becomes progressively wider since the pressure change duration last longer at lower frequencies. One period at 10 kHz is only 100 µs, at 1 kHz it becomes 1ms and at 100 Hz it is 10 ms. This is seen as an elongation of the dark red ridge in the time domain. As seen above the uncorected power response shows resonance within the room around 40-60ms after the inital impulse from the driver. It also shows a wave-shaped maroon band corresponding to the resonance of the bass frequencies changing in the room as time progresses.

Industry Standard Correction: Can Cause More Problems Than Solutions

Frequency Response Seems To Be Improved

But Unseen Stored Energy In The Time Domain Smears The Sound

The above shows a typical correction done to the loudspeaker resulting in a flattening of the frequency response. Most tote this as a more perfect reproduction of all frequencies between 25Hz and 24kHz however as seen to the above left...
The ordinary power response based correction system that only corrects the problem in the frequency domain has created a muddled mess of refelcted energy long after the initial impulse. Such high energy levels so late in time are not a good thing and the result can be perceived audibly by a muddled, artificial lower frequency response. This takes away alot of the crisp, clean, punchy low end that we're looking for.  

Eikon S-TRO Solves Room Interference

Frequency Response Doesn't Appear To Correct Much

The All Important Time Smear Is Dramatically Improved

The steady state power response diagram shown above details the correction done by Eikon's room analysis process. At first glimpse it doesn't look much better than original but remember, Eikon's wavelet processor looks at the response primarily in the time domain and not so much in the frequency domain, effectively rendering the power response diagram useless in determining the effect of the changes.
The image above shows the wavelet response after Eikon's S-TRO compensation. There is a remarkable improvement within the time domain now looking almost perfect up to approximately 2000 Hz where some energy from the reflections still remain. These frequencies are actually above the range where the correction predominantly operates. It is designed that way because the most audible difference is achieved below 700Hz. What the image also shows is that during at least the first 40 ms, the response from the loudspeaker in the room is more or less perfect without any aberrations.
