oudspeakers which reproduce sound in the mid and high-frequency
range are generally poor at reproducing low-frequency sounds. Bass
content is vital to movie effects and music to achieve a perceived
high sound quality. Bass enhancement boosts the low frequency part
of the signal and leaves the remaining part of the frequency range
unchanged in terms of loudness and timbre. This gives the
possibility to create extreme bass enhancement.
AM3D offers three dedicated bass enhancement solutions: A generic
solution optimised for mid-range loudspeakers and headphones, one
optimised specifically for micro-speakers used in e.g. mobile
phones, and a bass harmonics solution.
