how does one change the timbre of a sound

I was wondering how one changes the timbre of a sound without changing the
pitch.

One alters the relative strengths of the harmonics. There are many ways to so that, not all of them electronic. Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������

dude! you're spoilt for choice. if i were you i'd first decide _what_ sort of change in timbre you desire. obvious ideas... EQ, play it backwards, non linear changes in amplitude etc. -- Matthew, Torture Yourself - http://www.burnttoys.co.uk/

Igor, You can generate new harmonics by distorting the waveshape. Also, try AM and/or FM modulation of the sound by a low-frequency waveform. Regards, John

This has the faint odor of a homework question, but even presuming it's not, the question shows a lack of understanding of the relationship between timbre and harmonic content, and (as others indicated) the many ways harmonic content can be changed. May I suggest reading one or more of these books: "The Acoustical Foundations of Music" John Backus "Horns Strings And Harmony" Arthur H Benade "Music, Physics and Engineering" Harry F. Olson It's been a long time since I read the first two, and I don't even recall reading the third, but they should help. Also, read a few things on how music synthesizers work.

Interesting, when I taught Musical Acoustics at the U of
Arizona, Backus was my required text and the other two
topped the reading list.
