Re: [sc-dev] UnaryOpUGen with dbamp and ampdb broken for audio-rate?

[Julian Rohrhuber <julian.rohrhuber@xxxxxxxxxxxxxxxxxx>]

Here is a general test:

(
f = { |operator ... args|
	{
		var cases;
		cases = args.collect { |x|
			[
				x,
				DC.kr(x),
				DC.ar(x),
				Duty.ar(1, 0, Dseq([x])),
			]
		};
		cases.flop.collect { |x|
			var a, b;
			#a, b = x;
			K2A.ar(a.perform(operator, b))
		}
	}.loadToFloatArray(0.01, s, { |x| x.clump(4).at(100).postln })
};
)
f.value(\ampdb, 0)
f.value('+', 5, 4)
