Sound quality
When it comes to sound quality, not only do opinions differ, they often lead the discussion to a dead end.
As a general rule, the reason for this is a different understanding of the concept of quality. In this article, we will try to answer the fundamental questions and give clear definitions, which can undoubtedly help to bring these discussions to a common denominator.
But first, you need to give a clear definition of the concept of quality. The simplest way to do this is to establish a series of requirements for certain characteristics and processes, and subsequently identify the degree of compliance with them in relation to the characteristics of the result obtained. This definition originates from a slightly different area, but all of the above is also true in relation to sound. For example, even in the development phase, set the maximum allowable amount of harmonic distortions introduced into the audio signal as a result of either manipulation. Based on this, we can say that the closer the characteristics of the result are to the predetermined requirements, the higher the quality. However, some manufacturers may misuse this definition to make their products better than they really are. So purely hypothetical, by setting a low bar in principle you can theoretically improve the quality, at least on paper. This trick is often used by manufacturers of hi-fi equipment in the lower price segment, stating:
First of all, before starting a conversation about sound quality, this concept should be divided into two separate categories, which, on the one hand, are closely interconnected, and on the other hand, describe various aspects, both technical and aesthetic, and by therefore, they are often confused.
Audio quality
The concept of audio refers to all objects connected in one way or another and participating in the process of transmitting, processing and storing signals, whether in analog or digital form, that represent the original acoustic signal. An example of this can be both the sound source and the connection cables, mixers, equalizers, amplifiers, processors and speaker systems. Audio quality is determined by the degree of fidelity in the representation of the original audio signal, regardless of the deliberate nature of the manipulation (see below). Used in this case, the terms can be, for example, impedance, dynamic range, level, frequency range, volatility, signal-to-noise ratio and the like.
Sound quality
It describes the subjective judgment of what an individual listener heard, and is therefore often based on individual preferences, biases, and even biases. Furthermore, even visual aspects can influence subjective perception and judgment about sound quality. Looser terms are used when talking about sound quality, such as warmth, transparency, detail, density, brightness, or opacity.
To determine the sound quality of an audio system, you must first consider the sound quality of the source, as if there is no audio system between the listener and the sound source. Thus, for example, the sound quality of an instrument is made up of a combination of factors such as the melody of the composition, the virtuosity of the musician and, of course, the characteristic features of the instrument itself.
