Say, I need to generate 1 second, 2 ch, given bps and
sr wav filled with
(analog) 0.0 except for the only sample in middle with 1.0 value, or some
periodic sequence like { -1.0, -1.0, 1.0, 1.0, -1.0, -1.0, ... }, or something
else which can be described in few lines of C/Java-like language.
What is an appropriate software for such simple tasks?
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
