It is captured in the sampling process. It is made apparent by determining the harmonic structure and location of formants.

thanks for the reply :-)

what my point is..,

If I shouted this line(" �cogito ergo sum� � I think therefore I am
" )

think that the sound signal is sampled and played;

and you too shouted the same line and the sample is
captured and played;

now the problem is while we are playing the 2 files we will hear the
sound
" �cogito ergo sum� � I think therefore I am "

my tone is different from yours; how that information is captured ?
Is the(tone) information is related to the amplitude of a wave ?

I don't get what you mean by

sampling a sound by some X tone.

cud u simplify the case by using two different frequency sinusoids, or you
want to deal with human voices only?

thanks Hardy for the reply :-) basically, what my point is first we will sample a sound signal by a person A's tone, and then we will sample the 'same' sound signal by person B' s tone; we will play the 2 files separately shouted by 2 persons; same sound signal, but different tones; what my doubt is.., => How that "different" tones information was captured ? => Is the tone information related to the amplitude of the wave ? greetings nimo ______ If time travel is possible, then where are the tourists from the future? -STEPHEN HAWKING

This is a complex process when two voices are mixed. Voices are non- stationary and random in nature. Hardy

Hi..,

well, in frequency domain if we sample a "sound" signal,

actually we are sampling "amplitude values" at discrete places
of the wave.

what my point is..,

if we sample this simple sound wave shouted by 2 persons

=> " &#4294967295;cogito ergo sum&#4294967295; &#4294967295; I think therefore I am "

the sentences is same, but their "tones" are different

how that information( tone difference ) is captured ?

(1)  is the tone of a person is dependent on the amplitude
      of that wave ?

impossible. X-rays will prove to be a hoax.
