I want to store a file a.wav into a1.wav, but when i write it using above logic. It only creates a file "a1.wav" of 44 bytes, where as the actual size of file is around 700KB and when i listen that file, no sound in it.

so any idea, how to save a file.
please find the attched file for details.

thanks.

I dont, know why I am getting this error. when ever I test Media->Test Audio and MDI, i got this error. any body knows how to correct it?

Last day I tried a number of PD versions, from 38 to 40, but now this error is in all version. I also tried install/uninstall loop, but no benefit.

Either it is PD mad , or this error would help me in madness.

I want to load cyclone library that i copied in pd folder. when i use -lib cyclone. it is not loading? any idea , how to load external libraies in pd.

thanks.

what is the way to convert a signal into numbers.

adc~
| |
FFT~
| |
atan

After FFT~, I want to do (atan) of ratio of imaginary and real parts to calculate the phase. but imaginary and real parts are in signal from. Is there any way that i convert this signal into a number and then pass to atan (as atan demands a number input not a signal input).

or is there any variant of atan, who take signal input.

The formula to calculate the phase is

PHASE=atan(imaginary/real).

or is there any pd object that calculates the phase directly

thanks.

I want to do fft~ of a file named a.wav.
so when i read a file and attach it to fft~ object. it says fft~ inlet expected signal not a file.

I undersatnd the error , that fft need signal inlet , not the file.

so how I can do the fft~ of a wave file. I want to do the fft of a wav file (stored at disk) and then want to store the imaginary part in an array.

I have two array , Imaginary1 and Imaginary2 , each of length 512. I want to multiply each item of Imaginary1 to Imaginary2 and store it in third array Imaginary3.
So how I can do this?

I have an idea of tabwrite and tabread, but how to do manipulation at index level.

tabread Imaginary1 tabread Imaginary2

thanks.

I am using two simple objects.
adc~ and dac~. I want to control the output at dac~ in a left or right speaker. When i click left, voice should come only from left speaker and when i click right , voice should come from right. (just like the test sample of PD).

The test sample of PD use the toggle object but when i use toggle in my program for adc~ and dac~. It dont work.

Thanks.

I want to calculate the pitch (frequency) of a sound. so how I can calculate it using PD. Suppose there is a "dog.wav" file and I want to calculate the pith of dog sound .
thanks.

I want to convert person A voice into person B's voice. so can I do this using PD.
and if yes, what objects of pd would be used.

eg consider I want to change the pitch of voice into another pitch (male voice into female voice) , what objects of pd I should use.

As I am a new to pd, so I would highly appreciate the detailed answer.

Thanks.

these guys are actively working in speech processing domain. Few years back I also studied some of their papers to extract information. Have a look over their research work and even make a request for guidance , may be some one guide you as well.
