Te Fundamentals of Dynamic Range

Dynamic range, measured in decibels (dB), represents the ratio between the loodesto possible signal a system can handle before clipping and thee noise foor, thee level of background hiss or hum present even when no signal active. A wider dynamic range allows for greater contrast between quiet and loud passages, enabling more expressive and emotionally compelling performancedes.
