Hi all, in the .orc/.sco below, two sounds with a distance of about a semitone are listened, and there is lots of beating. In the .wav file attached there are midi-strings, and no beating are listened. How to avoid the beatings in the .orc./sco below? Note: with or without flanger, the beating is listened. sr = 22050

can you give working code? and i mean that the strings playing the semitone in the .wav file do no beat

You have two oscillators with frequencies pr and p4+a random small value. It is also a definition of beating.

Hi, If I understand correctly, the beatings in the first example comes from the multiple instances of i1 running at the same time with slightly different frequencies i1 0 20 160.001 i1 0 20 160.002 i1 0 20 160.003 i1 0 20 160.004 It does not really compare with the midi example, because there (I assume) you are playing one single note (then adding one more single note a semitone above) If you change the score to just i1 0 20 160.001 i1 6 14 170.001 then it will be more like the midi example.

When you superimpose 2 sine waves with frequencies f1 and f2 you get beat frequencies of abs(f1 - f2), so called sum and difference frequencies.

For a synth that I regularly use, I set iphs like so with some conservative float values: a1 oscil iamp, icps, ifn a2 oscil iamp, icps-.01, ifn a3 oscil iamp, icps+.01, ifn, .11 a2 and a3 have slight detune values, which would cause the phase beating. Plug in your own amp, freq and function and try it out. iphs is optional, note the first oscils have no initial phase offset. Offsetting the phase mitigates the beating.
