1. The algorithm can be used at any time, on music or voice calls
2. Simply press the IRIS button to activate.
3. Once activated, the audio stream will immediately be separated and phase shifted
between your ears, leading to active listening.
4. Parameters 'Intensity' and 'Integration' can be adjusted via the IRIS Listen Well
app. Integration adjusts the mix of the algorithm, whilst intensity adjusts the width
of phase separation.
How to use the algorithm
IRIS ALGORITHM
The IRIS algorithm is a revolutionary new audio experience that dramatically increases
sound quality while simultaneously activating your brain.
This is achieved through a proprietary algorithm which splits out and increases the
phase information sent to the brain. The listener’s brain then reassembles this vast
increase in information and becomes far more active in the listening process. This is
Active Listening.
The IRIS algorithm is not on by default, and should be switched on. This will lead to a
more immersive and engaging listening experience. It can also help with call clarity and
engagement
