Vibrato is properly computed +in units of pitch \, but it's also easy to add vibrato to the envelope--before +raising it to the fourth power \, so that it acts pseudo-logarithmically. +Rather than add to the ADSR output \, we multiply a signal which controls +relative frequency. The relative frequency change is one plus an oscillator. +; +#N canvas 153 366 686 470 guts 0; +#X obj 30 8 r trigger; +#X floatatom 68 403 0 0 0 0 - - -; +#N canvas 159 26 531 288 output 0; +#X obj 351 166 t b; +#X obj 351 114 f; +#X obj 351 62 inlet; +#X text 358 30 mute; +#X obj 351 192 f; +#X msg 442 185 0; +#X msg 351 88 bang; +#X obj 351 140 moses 1; +#X obj 413 122 moses 1; +#X obj 86 154 dbtorms; +#X obj 413 96 r master-lvl; +#X obj 86 44 r master-lvl; +#X obj 351 218 s master-lvl; +#X obj 24 163 inlet~; +#X obj 207 42 inlet; +#X text 207 19 level; +#X obj 207 104 s master-lvl; +#X msg 100 67 set \$1; +#X obj 100 93 outlet; +#X msg 222 66 \; pd dsp 1; +#X obj 86 202 line~; +#X obj 23 221 *~; +#X obj 23 250 dac~; +#X obj 86 178 pack 0 50; +#X text 22 140 audio; +#X obj 442 159 t b; +#X obj 21 191 hip~ 1; +#X connect 0 0 4 0; +#X connect 1 0 7 0; +#X connect 2 0 6 0; +#X connect 4 0 12 0; +#X connect 5 0 12 0; +#X connect 6 0 1 0; +#X connect 7 0 0 0; +#X connect 7 1 25 0; +#X connect 8 1 4 1; +#X connect 9 0 23 0; +#X connect 10 0 1 1; +#X connect 10 0 8 0; +#X connect 11 0 9 0; +#X connect 11 0 17 0; +#X connect 13 0 26 0; +#X connect 14 0 16 0; +#X connect 14 0 19 0; +#X connect 17 0 18 0; +#X connect 20 0 21 1; +#X connect 21 0 22 0; +#X connect 21 0 22 1; +#X connect 23 0 20 0; +#X connect 25 0 5 0; +#X connect 26 0 21 0; +#X restore 29 432 pd output; +#X msg 105 403 MUTE; +#X obj 30 268 *~; +#X obj 30 296 *~; +#X floatatom 65 99 5 0 100 0 - - -; +#X floatatom 30 99 1 0 100 0 - - -; +#X obj 29 347 +~ 0.3; +#X obj 29 373 cos~; +#X obj 29 321 osc~; +#X obj 65 122 mtof; +#X obj 65 147 sqrt; +#X obj 65 172 sqrt; +#X obj 30 238 *~; +#X obj 239 218 +~ 1; +#X obj 239 164 tabosc4~ array62; +#X floatatom 239 108 5 0 0 0 - - -; +#X obj 239 135 / 6; +#X obj 239 192 *~; +#X floatatom 393 145 5 0 0 0 - - -; +#X text 238 243 since we'll multiply \,; +#X text 237 258 vibrato output should; +#X text 237 275 be centered at 1 \, not 0; +#X text 278 194 multiply by vib depth; +#X obj 393 172 / 6923; +#X text 64 239 apply vibrato; +#X text 68 267 fourth; +#X text 71 283 power; +#X text 99 351 waveform; +#X text 98 331 simple; +#X text 468 166 4/(exp(log(2)/1200)-1); +#X text 472 147 conversion factor is; +#X text 386 101 vibrato depth; +#X text 385 118 in cents; +#X text 236 67 vibrato speed; +#X text 235 84 in Hertz; +#X obj 30 197 ../../doc/3.audio.examples/adsr 0 100 200 100 300; +#X obj 65 39 r pitch; +#X obj 232 10 r vibrato-speed; +#X obj 391 10 r vibrato-depth; +#X obj 44 65 t b f; +#X connect 0 0 7 0; +#X connect 1 0 2 1; +#X connect 2 0 1 0; +#X connect 3 0 2 2; +#X connect 4 0 5 0; +#X connect 4 0 5 1; +#X connect 5 0 10 0; +#X connect 6 0 11 0; +#X connect 7 0 37 0; +#X connect 8 0 9 0; +#X connect 9 0 2 0; +#X connect 10 0 8 0; +#X connect 11 0 12 0; +#X connect 12 0 13 0; +#X connect 13 0 37 1; +#X connect 14 0 4 0; +#X connect 14 0 4 1; +#X connect 15 0 14 1; +#X connect 16 0 19 0; +#X connect 17 0 18 0; +#X connect 18 0 16 0; +#X connect 19 0 15 0; +#X connect 20 0 25 0; +#X connect 25 0 19 1; +#X connect 37 0 14 0; +#X connect 38 0 41 0; +#X connect 39 0 17 0; +#X connect 40 0 20 0; +#X connect 41 0 7 0; +#X connect 41 1 6 0; +#X restore 491 32 pd guts; +#X text 10 166 I made a table with 6 cycles of vibrato and made small +changes with the mouse to get a not-exactly-repeating vibrato \, and +thus have to divide vibrato frequency by 6 You can just use a sine +or triangle wave if you prefer.; +#X obj 581 35 vsl 22 200 0 100 0 0 master-lvl empty volume -9 -8 1 +8 -225271 -1 -1 0 1; +#X obj 23 255 grid grid9 200 0 199 200 0 199 1 1 1 10 10 0 0; +#X obj 25 487 nbx 5 18 -1e+37 1e+37 0 0 vibrato-speed empty speed 0 +26 1 12 -233017 -1 -1 0 256; +#X obj 217 487 nbx 5 18 -1e+37 1e+37 0 0 vibrato-depth empty depth +-2 26 1 12 -233017 -1 -1 5970 256; +#X obj 392 296 tgl 55 0 trigger empty trigger 0 -9 1 10 -24198 -1 -1 +0 1; +#X obj 291 259 vsl 22 200 0 127 0 0 pitch empty pitch 0 -9 1 8 -62784 +-1 -1 0 1; +#X obj 25 463 * 0.2; +#X obj 217 464 * 30; +#X connect 6 0 11 0; +#X connect 6 1 12 0; +#X connect 11 0 7 0; +#X connect 12 0 8 0; -- cgit v1.2.1
