[sdiy] FM spectrum question

[jbv]

Hi list,

Don't know if it's the right place to ask but this is a question
I wanted to ask for a long time : is there a way (simple or not
- but I guess there's plenty of maths involved... may be is there
a piece of software than can compute that), a way to know which
parameters to use in FM synthesis (freqs, waveshapes...) in order
to obtain a specific spectrum, in which the freq & amp of each partial
is known in advance...

Best,
JB
