Music DSP presets
Music
The Music DSP preset extracts the mono and surround
components of the original recording. These components
provide an alternative representation of the original sound, and
this representation is sometimes used for recording systems or
in broadcasts such as FM radio.
The mono element is equalised using a proprietary Meridian
technique to match the tone colour of the centre speaker, and to
compensate for the fact that the frequency response of human
hearing changes with direction.
The Music DSP preset is recommended for recordings made
with spaced omnidirectional microphones, or using a mono-
surround technique.
Trifield
As for the Music DSP preset, the Trifield preset extracts the
mono and surround components of the original recording. It then
calculates the signals for the front left, centre, and right
speakers, using the phase and amplitude differences between
the three front channels, to redistribute the sounds on a
frequency-dependent basis.
The digital surround processor provides seven alternative music
DSP presets designed for the reproduction of well recorded
material, originally intended for replay over a traditional stereo
pair of loudspeakers.
In addition, it provides DSP presets for reproducing music in the
digitally encoded DTS, MPEG, and MLP formats.
