Exploiting natural hearing

While Working

at loudspeaker systems development
a new theory took place to unify the performance
of the two analogic links of an audio chain:

The Microphone – Psychoacoustics of Recording Room

The Loudspeaker – Psychoacoustics of Control Room

Audio Recording

There are at least four fundamental issues to be taken into account:

  • Localization of anisotropic non-point sources
  • Spatialization through non-coincident front stages
  • Conservative timbre & intensity
  • Isomorphic stereo-kinetic imaging

Two Channel Reproduction

relies on Point Source Hypothesis
saying it is possible to shift between two front loudspeakers
any acoustical source by means of “Amplitude and/or Time Delay Difference”.

This theory is faulting because every real source
is neither a point nor a pulsating sphere.

Inter-aural Crosstalk

Stereo loudspeaker listening
is always affected by this kind of interference which is
detrimental both for timbre & stage.

Binaural Technology

could be a nice solution but front/back reversal and fuzzy stage are definitely linked to individual HRTFs

Acoustic Power

of musical instruments is based on pressure sampling
next to the source but total radiation information
can only be gathered if also the velocity vector is known
to account for timbre correctness

A Brand New Concept

has been introduced to recover that part of energy largely wasted in standard control rooms and recording venues
that no electronic processor can bring back again

We gave it the name

Localization and Spatialization Augmentation by recovered rays
