0. NARRATIVE FORMULATION

“Fidelity requires a defined term of comparison.”

1. DEFINITION

The pattern reference is the representation encoded in a properly made stereophonic recording adopted as the reference for the specific assessment. It does not coincide with a possible antecedent acoustic event considered in its physical entirety, nor with an abstract idea of natural sound. The recording may derive from the capture of a unitary acoustic event or may be constituted in the master through the integration of partial source events, directly acquired signals, synthetic sources, algorithmic generation or post-production processes.

2. POSITION WITHIN THE THEORY*

The recording delimits what the chain is required to make available. Proper production qualifies its technical admissibility; adoption as the reference establishes its comparative function. Where a unitary sound event comes into existence only in the finalised stereophonic master, that master represents the first complete, canonical and native form of the reference. Intentionally encoded transformations form part of the pattern and are not to be cancelled or reinterpreted by the reproduction system.

3. RELATIONSHIPS AND OPERATING CONDITIONS

4. PERCEPTUAL TRANSLATION

The listener does not necessarily compare the reproduction with a complete memory of an antecedent acoustic event, which may not even have existed as a unitary event. The listener assesses the unity, stability and plausibility of the information made available. The operational reference enables this assessment to be separated from aesthetic preference and personal expectations.

5. MEASUREMENT, EVIDENCE AND LIMITS

The choice of reference must be preregistered or otherwise declared. A recording unsuitable for the specific verification may render the test inadmissible or inconclusive. Greater pleasantness does not establish greater fidelity; directionality must be referred to the content actually encoded in the master.

6. TRANSLATION WITHIN THE AURORA Electron Devices® TECHNICAL-SCIENTIFIC FRAMEWORK

'AURORA' uses selected recordings and known conditions to assess chain behaviour and to establish listening and installation procedures. Design is not oriented towards conforming to a particular recording taste, but towards containing intrinsic contributions that may alter its structural relationships.

7. OPERATIONAL SUMMARY

Pattern reference = a properly made stereophonic recording adopted as the operational term of the assessment, including acquired, generated or constructed relationships intentionally encoded in the master.
