Broadband impulse When this is selected the signal rate parameter is used to control rate White Noise correlated sends identical white noise to all outputs e White Noise decorrelated sends decorrelated white noise to all outputs Pink Noise correlated sends identical pink noise to all outputs Pink Noise decorrelated sends decorrelated pink noise to all outputs SPREAD EARLY SPREAD The spread parameter is closely tied to the Shape parameter Spread is a window of time during which a signal is injected into the reverb Shape controls just how the signal is injected during this window TAIL WIDTH This parameter is present in all stereo reverbs and rooms The reverb tail all components of the reverb except for early reflections etc is passed through a simple 2x2 matrix This provides an encoding of the tail that dramatically changes its spatial characteristics The tail can be changed to feel narrower even down to mono or wider than normal stereo There are values for the parameter to encode the tail in such a way that it decodes into surround channels The parameter operates in the range of 0 to 360 degrees with an incremental change of 1 degree The matrix uses Sine Cosine rules so that power distribution remains constant This may be acceptible even highly desirable but the mix engineer must fully understand the process and its implications This is a powerful tool for audio whose releas

25. AND MONO A hall is the principal venue for classical ensembles but has proven to be useful for all types of music A hall is comparatively large with wall to wall distances that are typically several tens of meters Smaller halls may be used for smaller ensembles The characteristic sound of a hall includes very low initial reflection density with little reflection energy before 60 100 milliseconds Density buildup is more gradual because of the larger distances between reflecting surfaces Reverberation time is somewhat longer as well Finally in most halls lower frequencies reverberate longer than higher frequencies This new hall algorithm shares these basic characteristics with Random Hall and Concert Hall but is smoother with a more even decay Its initial density is also lower than Random Hall so it may be a better choice when the reverberation needs to be unobtrusive RANDOM HALL STEREO AND MONO Random Hall is a hall effect with gradual build up well suited to complex sounds like orchestral music Its reverberators change over time in controlled random ways to avoid the buildup of tinny grainy metallic or other colorations The modulation can be noticeable and is often a desirable effect The early reflections are user adjustable in amplitude and delay Some skill is needed to set useful reflection patterns The pattern can be expanded or contracted in time using the Delay Master control and the overall level of th
