Análisis de parámetros objetivos y subjetivos en Pre-Amplificadores de Audio
El siguiente artículo explica los resultados de las mediciones en cinco (5) diferentes pre-amplificadores, entre estado sólido y válvulas al vacío, de parámetros objetivos de THD –Análisis de Fourier- y función de transferencia, y parámetros subjetivos de calidez y brillo, en una muestra no probabilística de expertos con ingenieros de grabación que cuentan con una experiencia entre quince (15) y veinticinco (25) años, con el fin de encontrar una correspondencia directa entre estos parámetros y determinar qué elementos electrónicos están relacionados con la percepción auditiva de calidez y brillo en una grabación realizada con estos dispositivos.
