Sounding Vowels with FOF

Subject	Sounding Vowels with FOF
	Hello everyone, I executed the Fof's manual example to produce an alto "a", and besides it doesnt seems much like an "a", I thought of an orchestra of five instruments to make the a-e-i-o-u choral. So I looked up the Appendice from the manual with the Formant Frequencies and bandwidth. Ok, the Appendice table give us the formant frequency, the bandwidth and the amplitude for each component of each vowel, but how to know the "fundamental" frequency for a vowel? The table didn't have to have four components: fundamental, formant, bandwidth and amplitude, instead of just four? I tried to use the fundamental from the vowel "a" manual example, using the same fundamental to all the vowels and modifying the components following the Formant Appendice for each vowel, but it resulted in inaudible es, is, os and us. What fundamental we need to use for the other vowels? There is other FOF parameters we have to modify? The Formant Frequencies Appendice is incomplete? Below is my modified manual example for all the vowels: --------------------- -o fof.wav sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; alto com o som de "a" instr 1 kfund = 261.659 koct = 0 kris = 0.003 kdur = 0.02 kdec = 0.007 iolaps = 14850 ifna = 1 ifnb = 2 itotdur = p3 kamp1 = ampdb(0) kform1 = 800 kband1 = 80 kamp2 = ampdb(-4) kform2 = 1150 kband2 = 90 kamp3 = ampdb(-20) kform3 = 2800 kband3 = 120 kamp4 = ampdb(-36) kform4 = 3500 kband4 = 130 kamp5 = ampdb(-60) kform5 = 4950 kband5 = 140 a1 fof kamp1, kfund, kform1, koct, kband1, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a2 fof kamp2, kfund, kform2, koct, kband2, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a3 fof kamp3, kfund, kform3, koct, kband3, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a4 fof kamp4, kfund, kform4, koct, kband4, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a5 fof kamp5, kfund, kform5, koct, kband5, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur out (a1+a2+a3+a4+a5) * 16384 endin ; alto com o som de "e" instr 2 kfund = 200 koct = 0 kris = 0.003 kdur = 0.02 kdec = 0.007 iolaps = 14850 ifna = 1 ifnb = 2 itotdur = p3 kamp1 = ampdb(0) kform1 = 400 kband1 = 60 kamp2 = ampdb(-24) kform2 = 1600 kband2 = 80 kamp3 = ampdb(-30) kform3 = 2700 kband3 = 120 kamp4 = ampdb(-35) kform4 = 3300 kband4 = 150 kamp5 = ampdb(-60) kform5 = 4950 kband5 = 200 a1 fof kamp1, kfund, kform1, koct, kband1, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a2 fof kamp2, kfund, kform2, koct, kband2, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a3 fof kamp3, kfund, kform3, koct, kband3, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a4 fof kamp4, kfund, kform4, koct, kband4, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a5 fof kamp5, kfund, kform5, koct, kband5, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur out (a1+a2+a3+a4+a5) * 16384 endin ; alto com o som de "i" instr 3 kfund = 261.659 koct = 0 kris = 0.003 kdur = 0.02 kdec = 0.007 iolaps = 14850 ifna = 1 ifnb = 2 itotdur = p3 kamp1 = ampdb(0) kform1 = 350 kband1 = 50 kamp2 = ampdb(-20) kform2 = 1700 kband2 = 100 kamp3 = ampdb(-30) kform3 = 2700 kband3 = 120 kamp4 = ampdb(-36) kform4 = 3700 kband4 = 150 kamp5 = ampdb(-60) kform5 = 4950 kband5 = 200 a1 fof kamp1, kfund, kform1, koct, kband1, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a2 fof kamp2, kfund, kform2, koct, kband2, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a3 fof kamp3, kfund, kform3, koct, kband3, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a4 fof kamp4, kfund, kform4, koct, kband4, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a5 fof kamp5, kfund, kform5, koct, kband5, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur out (a1+a2+a3+a4+a5) * 16384 endin ; alto com o som de "o" instr 4 kfund = 261.659 koct = 0 kris = 0.003 kdur = 0.02 kdec = 0.007 iolaps = 14850 ifna = 1 ifnb = 2 itotdur = p3 kamp1 = ampdb(0) kform1 = 450 kband1 = 70 kamp2 = ampdb(-9) kform2 = 800 kband2 = 80 kamp3 = ampdb(-16) kform3 = 2830 kband3 = 100 kamp4 = ampdb(-28) kform4 = 3500 kband4 = 130 kamp5 = ampdb(-55) kform5 = 4950 kband5 = 135 a1 fof kamp1, kfund, kform1, koct, kband1, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a2 fof kamp2, kfund, kform2, koct, kband2, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a3 fof kamp3, kfund, kform3, koct, kband3, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a4 fof kamp4, kfund, kform4, koct, kband4, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a5 fof kamp5, kfund, kform5, koct, kband5, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur out (a1+a2+a3+a4+a5) * 16384 endin ; alto com o som de "u" instr 5 kfund = 261.659 koct = 0 kris = 0.003 kdur = 0.02 kdec = 0.007 iolaps = 14850 ifna = 1 ifnb = 2 itotdur = p3 kamp1 = ampdb(0) kform1 = 325 kband1 = 50 kamp2 = ampdb(-12) kform2 = 700 kband2 = 60 kamp3 = ampdb(-30) kform3 = 2530 kband3 = 170 kamp4 = ampdb(-40) kform4 = 3500 kband4 = 180 kamp5 = ampdb(-64) kform5 = 4950 kband5 = 200 a1 fof kamp1, kfund, kform1, koct, kband1, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a2 fof kamp2, kfund, kform2, koct, kband2, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a3 fof kamp3, kfund, kform3, koct, kband3, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a4 fof kamp4, kfund, kform4, koct, kband4, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur a5 fof kamp5, kfund, kform5, koct, kband5, kris, \ kdur, kdec, iolaps, ifna, ifnb, itotdur out (a1+a2+a3+a4+a5) * 16384 endin f 1 0 4096 10 1 f 2 0 1024 19 0.5 0.5 270 0.5 i 1 0 1 i 2 1 1 i 3 2 1 i 4 3 1 i 5 4 1 e --------------------------------------------- _________________________________________________________________ http://signup.alerts.msn.com/alerts/login.do?PINID=2430448&returnURL=http://copa.br.msn.com/

	You can use any fundamental you desire. I've posted an example at http://www.eng.hmc.edu/Csound/SingAve.csd of using the formants and fof to create a singing voice. The soundfile is at http://www.eng.hmc.edu/Csound/SingAve.mp3 The example also has examples of using buzz and filters as well as using the voice and the fmvoice opcodes to compare synthesized singing in Csound. By picking the instrument and formant table you can choose gender and vowel for any of the four and compare them. Fof usually, but not always sounds best.
