The current way to do this is to write the fsig to a pair of tables with pvsftw, then manipulate the table data as you see fit with the many facilities provided for manipulating tables, then read from the tables with pvsftr.

You may also want to look at the ATS opcodes for partial manipulation.

ATSpartialtap is probably the one. Use the output data to control an
oscillator's frequency and amplitude.

Note that you need to set 0dbfs=1 in the orchestra header.

Yes one of the oscil opcodes. I'd use poscil3 for higher precision and
better sound quality. You need to set the kr very high as well since
the returned frequencies and amplitudes are control-rate.

ATSBUFREAD: time pointer out of range, truncating to last frame.

 ipartials – number of partials that will be used in the resynthesis (the noise has a maximum of 25 bands).

Dear Peiman,
thank You very much!
Your code works fantastic.
I'd never thought that changing the partials of an natural sound could be done in such an easy way.
I've just two more questions:
1. Sometimes I get the error message

ATSBUFREAD: time pointer out of range, truncating to last frame.

          What does it mean and how can I avoid it?
2. I've read in the csound manual about ATSbufred:

 ipartials – number of partials that will be used in the resynthesis (the noise has a maximum of 25 bands).

            Does it mean that I can't use more than 25 partials?

2010/11/29 Stefan Thomas <kontrapunktstefan@googlemail.com>

Dear Peiman,
thanks for Your tipp.
For sure I will try Your code.
But let me ask me one more question:
Will ATSpartialtap also "know" the attack and decay times of the the individual partials?

2010/11/29 peiman khosravi <peimankhosravi@gmail.com>

Yes one of the oscil opcodes. I'd use poscil3 for higher precision and
better sound quality. You need to set the kr very high as well since
the returned frequencies and amplitudes are control-rate.

By way of a side note on such things - if one wants to be sure the 
target pitch as such is perceived by the user,  at the end of the sound, 
the pitch needs to be reached (and maybe held) a little before the end.

1- Yes exactly. This error can be ignored.

2- The second point is related to the noise bands not the partials.
The residual part of the signal (the part that cannot be broken into
individual sine components) is written in the analysis file as a
collection of band-pass filters (with different band-widths) and used
to filter noise to synthesize the residual signal (this is useful for
say re-synthesizing a flute sound). If you are just working with the
partials and ignoring the noise part then the 25 band limit does not
apply.

Best,

Peiman

Do you mean th efrequency and amplitude values?

You can just write them into a table by using tabw oe something.
