Your experience of sound is more than just "vibrations" travelling through the air
SHAPE follows the way hearing changes across level and frequency, helping music stay full, detailed, and controlled when the volume changes.
How It works
Different sound levels affect how loud low and high frequencies are perceived compared to mid frequencies. SHAPE and Perception compensate for that psychoacoustic shift.
