[question] - how can i rotate the phase of a Whitenoise.ar or Soundin.ar object in supercollider? in the version of supercollider i have installed they don’t seem to have like an argument for phase. how wonder how can i implement this?

i fixed this with, and i even got like one or two further examples:

 (
    SynthDef("help-phaseShift", { arg out=0;
            var in, chain;
    	    in = SoundIn.ar([0,0]);
    	    in = WhiteNoise.ar(in);
            chain = FFT(LocalBuf(2048), in);
            chain = PV_PhaseShift(chain, 32);
    	    out = 0.1 * [IFFT(chain).dup + in];
    	    out = Mix.new(out);
    	    Out.ar(0, out);
    }).play(s);
    )
    
    (
    {
    var signal, delay, reverb, in, chain, meinenSignal;
    in = SoundIn.ar([0,0]);
    in = WhiteNoise.ar(in);
    chain = FFT(LocalBuf(2048), in);
    chain = PV_PhaseShift(chain, 32);
    chain = [IFFT(chain).dup + in];
    meinenSignal=Mix.new([in+chain]);
    signal = Mix.fill(10, {Resonz.ar(meinenSignal, rrand(200.0, 3200.0), 0.003)});
    delay = DelayN.ar(signal, 0.048);
    reverb = Mix.fill(7,{CombL.ar(delay, 0.1, LFNoise1.ar(0.1.rand,0.04,0.05), 15)});
    4.do{ reverb = AllpassN.ar(reverb, 0.050, [ 0.050.rand, 0.050.rand ], 1) };
    signal + (reverb * 0.2)
    }.play
    )
    
    (
    {
    var signal, delay, reverb, in, chain, meinenSignal;
    in = SoundIn.ar([0,0]);
    in = WhiteNoise.ar(in);
    chain = FFT(LocalBuf(2048), in);
    chain = PV_PhaseShift(chain, 32);
    chain = [IFFT(chain).dup + in];
    meinenSignal=Mix.new([in+chain]);
    signal = Mix.fill(10, meinenSignal);        
    delay = DelayN.ar(signal, 0.048);        
    reverb = Mix.fill(7,{CombL.ar(delay, 0.1, LFNoise1.ar(0.1.rand,0.04,0.05), 15)});
    4.do{ reverb = AllpassN.ar(reverb, 0.050, [ 0.050.rand, 0.050.rand ], 1) };
    signal + (reverb * 0.2)
    }.play
    )

Hello @tmm881

You might also like to try the Hilbert Transform Quark Library. This includes phase rotation as well as some other tricks…
