-#X text 80 322 amplitudes (dB);
-#X text 68 26 This patch attempts to scrub the noise floor from a sample
-in two steps. First using the "make-mask" message (which is caught
-in the "fft-analysis" window) \, you estimate the background spectrum.
-You would normally do this at a moment when only the background noise
-is audible. Then \, turn on "masking" (to 15 by default \, but try
-other values) and the patch will try to clean the background noise
-out of a signal.;
-#X text 67 149 For this demonstration \, you control the amplitudes
-of a looping sample and a filtered noise source. Normally you'd hit
-"calculate noise mask" with only hte noise turned on \, then turn both
-the noise and the sampler on \, and also "masking" \, to see if the
-patch can clean the noise out of the signal. Open the "fft-analysis"
-window to see the algorithm \, or the "insample" window to change samples
-\, or "mask-table" to see the current mask (the average signal power
-of the noise to clean out of the signal).;
