When do and do# are played together by strings (as in the midi-strings wave attached) the interval sounds wonderful. When do and do# are played together by the instrument below, there is a BOTHERING, UGLY beating. According to my poor acoustics knowledge, the beatings should be listened too at the midi-strings wave attached, but it does NOT happen. The question is: what is needed to be added to the instruments below to avoid the beatings?? Please send code, NOT explanations. As a beginner, explanations will ONLY confuse more and more. Thanks in advance. <CsoundSynthesizer> <CsOptions> -odac -d </CsOptions> <CsInstruments> sr = 44100 ksmps = 32 nchnls = 2 0dbfs = 1 instr 1 kvol linseg 0,p3*.05,1,p3*.9,1,p3*.05,0 asig oscil kvol*.7,p4 ,1 out asig,asig endin </CsInstruments> <CsScore> f1 0 4096 10 1 .5 .25 .1 i1 0 20 160 i1 3 14 170 </CsScore> </CsoundSynthesizer> |

Can you explain the 160Hz and 170Hz in your program? I would expect
beating at 10 times a second (10 = 170-160).
I am not sure what "do" and "do#" mean and how they relate to 169 and 179
Hz so hard to provide code.

Not sure which beating you are refering to, but with 10hz difference you could be experiencing 10hz binaural effect. Also this isn't nececcarily a equally-tempered interval (160hz and 170hz). You could use some reference if you want to use absolute herz values http://www.sengpielaudio.com/calculator-notenames.htm You can also use cpsmidinn to convert midi value to freq <CsoundSynthesizer> <CsOptions> -odac -d </CsOptions> <CsInstruments> sr = 44100 ksmps = 32 nchnls = 2 0dbfs = 1 instr 1 kvol linseg 0,p3*.05,1,p3*.9,1,p3*.05,0 ifreq = cpsmidinn(p4) asig oscil kvol*.7,p4 ,1 out asig,asig endin </CsInstruments> <CsScore> f1 0 4096 10 1 .5 .25 .1 i1 0 20 40 i1 3 14 41 </CsScore> </CsoundSynthesizer> On Fri, 30 Aug 2019 at 18:25, Csounder Csounder <0000017e1be09e0e-dmarc-request@listserv.heanet.ie> wrote:

sorry didn't do this right, (fix from my previous reply would be): instr 1 kvol linseg 0,p3*.05,1,p3*.9,1,p3*.05,0 ifreq = cpsmidinn(p4) asig oscil kvol*.7,ifreq ,1 out asig,asig endin On Fri, 30 Aug 2019 at 18:36, Hlöðver Sigurðsson <hlolli@gmail.com> wrote:

In short I want to generate two sounds with near frequency that sound together without beatings as in the .wav file i attached (here again). When the frequency of two sounds are near as in the code below (it does not matter if the frequencies are 160-170, or 170-180, or whatever) a horrible beating is listened, and i have no idea how to avoid that. Can you provide the code? i mean the instruments and the score? <CsoundSynthesizer> <CsOptions> -odac -d </CsOptions> <CsInstruments> sr = 44100 ksmps = 32 nchnls = 2 0dbfs = 1 instr 1 kvol linseg 0,p3*.05,1,p3*.9,1,p3*.05,0 asig oscil kvol*.7,p4 ,1 out asig,asig endin </CsInstruments> <CsScore> f1 0 4096 10 1 .5 .25 .1 i1 0 20 160 i1 3 14 170 </CsScore> </CsoundSynthesizer>

I DO here beatings in the strings example, namely a 'tremolo' kind of effect as soon as the second note is played. It is a well known fact that an interval like c-e played very low on a piano does not sound as good as the same interval played a few octaves higher. That is because musical notes are not on a lineair scale, so the frequency difference in the lower played interval is not the same as in the higher one...

i tink you are seeking to deny basic mathematics physics and acoustics.
You can minimue beating effects wuth just intonation but you cannot ovecoe
reality.

These beating would come from violins too, depending on the violins, the vibrato and the dozens (hundreds) of overtones playing togeather, will make the the binaural effect way less audible. That's why simple sinewaves are usually picked when pseudo-science people online make binaural "drugs" (an example is here https://www.youtube.com/watch?v=3diYC2J8icc) here you can listen with headphones and compare left and right channels. This is the same phenomena that you're experiencing, except in 2 channels (the brain will will in the gap).

I'll try to express myself even more clearly: how to get the two sounds in the .csd file below to sound so wonderful (that means without beatings or almost) as the two sounds in the .wav file? anyone has some instrument/s like that and agree to share? <CsoundSynthesizer> <CsOptions> -odac -d </CsOptions> <CsInstruments> sr = 44100 ksmps = 32 nchnls = 2 0dbfs = 1 instr 1 kvol linseg 0,p3*.05,1,p3*.9,1,p3*.05,0 asig oscil kvol*.7,p4 ,1 out asig,asig endin </CsInstruments> <CsScore> f1 0 4096 10 1 .5 .25 .1 i1 0 20 160 i1 3 14 170 </CsScore> </CsoundSynthesizer>

| The relationship between perceived dissonance and timbre is complex. A semitone played by a piano will always sound more dissonant than a semitone played by a violin section. Among the reasons for this are two: the sudden high frequency content of the piano attacks and the chorus effect of the violin section, which helps mask the beating.
