Finally implemented perceptual brightness thing.

classdef sigdrop < signal
	properties (GetAccess=private, SetAccess=immutable)

		function s=tostring(sig)
			s=sprintf('drop(%d,%s)',sig.todrop,tostring(sig.sig));

		function c=rate(s), c=rate(s.sig); end
		function c=channels(s), c=channels(s.sig); end

			s.start();
