Audio is Science
All of the devices used to capture, store and reproduce musical, theatrical and film performances are designed by engineers who apply the laws of physics as they pertain to the functioning of these devices. Perfection, in this context, is defined as not degrading any part or any aspect of the audio signal: the art itself. Determining how close we are to perfection is ultimately determined subjectively, in carefully-controlled listening tests. However, accurate and comprehensive measurements, interpreted using the ever-expanding ‘rules’ of psychoacoustics, are remarkably accurate predictors of what is and what is not audible and, ultimately, of subjective preferences. This allows us to design better sounding and more cost effective products.
Audio is Art
The melodies and rhythms of music, the nuances of tone and infl ection of instruments and voices, the emotive effects of sometimes subtle, sometimes explosive, sound effects in movies … are aspects of art for which there are no scientific or technical measures. Yet, subjectively we have little difficulty describing our reactions, positive and negative, when we hear these sounds. Perfectly reproduced, they should sound exactly as they did at the live performance or in the control room where the recording was mixed. Achieving this lofty goal is a considerable challenge, since the fi nal audio component is the listening room, and all rooms are different. The interactions among loudspeakers, listeners and rooms are the focus of continuing scientific investigations.

P.D. No actualizo porque no tengo tiempo, estoy muy liado con los exámenes. Tengo un par de articulillos, que en cuanto los acabe, los postearé. Uno es de lo que me faltaba de acústica, tema de reflexión y refracción del sonido, y después otro que ya me meto en lo que es un altavoz, sus partes, características. De mientras, os dejo este excelente artículo de Floyd, vicepresidente de Harman. Lo tengo traducido, luego a la noche edito el post y lo pongo, para el que le interese.
