Almost anything, to be honest. If you're comfortable with python then
maybe that, or octave if you know that, if you're comfortable with
Audacity maybe learn how to use the "nyquist prompt".

I use SuperCollider, here's one of your cases done in an interactive session:

~seconds = 1;
~samplerate = 44100;

c = [-1, -1, 1, 1].wrapExtend(~samplerate * ~seconds).stutter(2).as(Signal)

c.plot(numChannels: 2)
c.play(numChannels: 2, mul: 0.05) // BE CAREFUL, turn yr speakers down

f = SoundFile("test.aiff").numChannels_(2);
f.openWrite;
f.writeData(c)
f.close
