+#X text 31 316 codepend~ is a classic "block convolution" processor.
+It performs a complex multiply upon the spectra of two input signals.
+Multiplication of spectra can cause significant drops in the amplitude
+of the output signal. The invert message causes codepend~ to perform
+complex division of the input spectra rather than multiplication. This
+can cause huge amplitude gains. A "pad" message is provided to allow
+for empirical amplitude balancing between the normal and "invert" states.
