audio - How to write a wah-wah sound effect in C++? -

-

i'm trying learn write wah-wah sound effect. fun :)

so far, i've done lot of research, , page explains best. http://www.geofex.com/article_folders/wahpedl/voicewah.htm

basically, i'm looking simple c++ examples generate wah-wah (ooaaooaa) effect.

eventually once done, hope able create "eeeoooeeeoo" effect, or "eeaaeeaa" effect :) sort of vowel sythnthesis, music.

if find examples i'll link them here.

...

i'm having trouble mathematical side of things.

what waves need generate make "e" sound? waves need generate make "o" sound?

i did try making 2 frequencies, harmonics, according page, , adjusting 2 frequencies, still sounded electronic beeps, not vowels.

...

http://www.acoustics.hut.fi/publications/files/theses/lemmetty_mst/chap3.html seems good. there numbers can use. sound "vowelish".

edit: tried making sounds @ frequencies mentioned on page (100hz,600hz,1000hz,2500hz). did not sound "vowelish". maybe slightly, not properly.

so need more frequencies make proper "a" sound. although i'm not sure frequencies.

i record own voice. , maybe download otherpeople speaking vowels. , find spectrum analyser app. tried searching spectrum analyser app, , first 1 found wouldn't work on sound files microphone input. seems lot more work trying find spectrum analyser app need. might need write own.

shame can't find resource list of requencies generate vowel from... can learn this. , using knowledge, develop "vowel filter" works wahwah "ioio" or "eaea" sounds.

right now, amount of effort need do:

  • download vowels
  • test perhaps 4 apps see if can analyse frequency spectrums file
  • generate frequencies spectrum
  • test frequencies see if sounds "vowel-like"

its not "fun" anymore. work. shame. have other (real) work doing. i'll park 1 until find enough answers make project fun work on.

about sounding vowel, should @ formants. in synthesizing voice.

passing sound thru formant filter may lead precisely effect want.

edit: insist formant filter is not wah-wah effect. wah-wah effect simple bandpass filter. formant filter more complex.

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
