Random Hall Page Two
BAS (Bass Multiply)
BAS sets the reverb time for low-frequency signals, as a multiplier of the RTM
parameter. For example, if BAS is set to 2X, and RTM is set to two seconds, the
low frequency reverb time will be four seconds. For a natural-sounding hall
ambience, we recommend values of 1.5X or less.
XOV (Bass Crossover)
XOV sets the frequency at which the transition from RTM to BAS takes place.
XOV should be set at least two octaves higher than the low frequency you want
to boost. For example, to boost a signal at 100 Hz, set XOV to 400 Hz (This
setting works well for classical music). XOV works best around 400 for boosting
low frequencies, and around 1.5 kHz for cutting low frequencies.
TDC (Treble Decay)
TDC sets the frequency above which sounds decay at a progressively faster
rate. It filters all the sound except the pre-echoes. When set relatively low, it gives
a darker tone to the reverberation, simulating the effect of air absorption in a real
hall. TDC also helps keep the ambience generated by the program from
muddying the direct sound.
DIF (Diffusion)
DIF controls the degree to which initial echo density increases over time. High
settings of DIF result in high initial buildup of echo density, and low settings cause
low initial buildup. Echo density is also affected by SIZ; smaller spaces will sound
denser. To enhance percussion, use high settings of diffusion. For clearer and
more natural vocals, mixes, and piano music, use low or moderate settings of
diffusion.
LNK (Link)
When LNK is set, the reverb time and spread values scale linearly as the SIZ
control is varied. For some special effects, RTM and SPR can be unlinked.
RLVL (Reverb Level)
RLVL sets the amount of reverberation in the processed signal. It is normally
FULL, but may be reduced for effects where the pre-echoes should dominate.

SPN (Spin)
SPN affects the movement of the reverberation tail. The object of SPN (and
WAN) is to continuously alter the timbre of the reverberant sound. This makes
the result more natural, without making the position of instruments unstable.
SPN should typically be 20 or higher. High values may make the pitch of piano
or guitar unstable.
WAN (Wander) WAN sets the distance in time that the early reflections will move. For best results
WAN should be about 10ms at larger sizes, and 5ms for smaller sizes.
RTM (Mid-Frequency
RTM sets the reverb time for mid-frequency signals. Because low-frequency
Reverb Time) reverb time (BAS) is a multiplier of RTM, RTM acts as a master control for the
reverb time.
