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 => " �cogito ergo sum� � 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 ? ______ greetings nimo Radio has no future. Heavier-than-air flying machines are impossible. X-rays will prove to be a hoax. -PHYSICIST LORD KELVIN , 1899
sampling sound, how to capture the information of different "tones" ?

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?>On May 17, 12:03=A0pm, HardySpicer <gyansor...@gmail.com> wrote: >> On May 17, 7:08=A0am, Nimo <azeez...@gmail.com> wrote: >> >> >> >> > 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 >> >> > =3D> " =91cogito ergo sum=92 =96 I think therefore I am " >> >> > the sentences is same, but their "tones" are different >> >> > how that information( tone difference ) is captured ? >> >> > (1) =A0is the tone of a person is dependent on the amplitude >> > =A0 =A0 =A0 of that wave ? >> > ______ >> >> > greetings >> > =A0 =A0nimo >> >> > Radio has no future.

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 ? greetings nimo _____ �cogito ergo sum� � I think therefore I am Ren� Descartes(1596�1650) On May 19, 2:01�am, "wiltonmagik" <wilton.ma...@gmail.com> wrote:> 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? > > >On May 17, 12:03=A0pm, HardySpicer <gyansor...@gmail.com> wrote: > >> On May 17, 7:08=A0am, Nimo <azeez...@gmail.com> wrote: > > >> > 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 > > >> > =3D> " =91cogito ergo sum=92 =96 I think therefore I am " > > >> > the sentences is same, but their "tones" are different > > >> > how that information( tone difference ) is captured ? > > >> > (1) =A0is the tone of a person is dependent on the amplitude > >> > =A0 =A0 =A0 of that wave ? > >> > ______ > > >> > greetings > >> > =A0 =A0nimo > > >> > Radio has no future.
