#X text 221 262 vacancy~ performs spectral compositing. The threshold
controls the compositing and is specified in dB. Useful values lie
in the range from -90 dB to 90 dB. Threshold inversion is available
via the invert message. The threshold can also track the current RMS
value of of the signal. In RMS tracking mode \, the useful threshold
range will be somewhat different depending upon the character of the
input signals. Phases will be derived from the left input unless phase
swapping is specified. In this case phases will be taken from the right
input signal when the threshold test is true.;
