Reverberation with the MU-R201
When trying to recreate the ambient sound field by means of
digital signal processing, using two monaural reverberator
units does not produce fully satisfactory results. The width
and depth of the sound stage present in the stereo will not be
preserved with such an arrangement. This becomes obvious
by picturing for example a sound which originates from the
right side of the stage. Its early reflections on the right will
reach the listener earlier than the reflections on the left, and
the reverberant sound field also gradually spreads from the
right. To achieve natural-sounding reverb in such a case
requires a reverberator which provides stereo inputs, stereo
signal processing, and stereo outputs. In the MU-R201, this
goal is achieved by the use of a two-channel digital audio
signal processing LS! and latest stereo algorithms, producing
natural and effective reverberation of very high quality.
Different algorithms are required for delay effects, gate reverb
effects, and auto-panning effects. All algorithms were newly
developed for the MU-R201 and form the basis of the ten
different effect modes (0-9). By using these modes in
combination with suitable parameters, a multitude of
impressive and striking effects can be created.
