Hi Everyone,
Is it possible that when we burn any of the CD, it shouldn't get copied on any PC or it should not get Burned.if possible please send a sample.
Thanx in Advanced.

Trying to get your question...
Are you asking about code which will burn CD on the fly means without copying it on HD?

If I'm right, there's something called "Copyright protection" or copy protection. But that merely shows a message that the disc is copy-protected when someone makes a copy. You cannot prevent a disc from being copied. Any disc consists of merely data, not a running program which can decide what to do.

Hi
can any one help me how to segment a speech wave file based on shortpauses between the words in the wavefile,I need to parse the wave file for pause if I get it I will take the word content and make a new wave file and again parse the old one for next pause and make the new
file...
the difficulty I am facing is how to get the pause in a wave file.
thanks for help from any one,
regards
vamshi

what sound API are u using or how have u read in and stored the raw data?
i guess how i would do it would be to either do a raw data check to see if the current sound buffer had a series of zeros in it. this wont work if you have microphone data because of noise etc.
otherwise you could FFT analyse the buffer to see if there exsists a freq in the audiable spectrum range with a magnitude of X, where X is your tolerance of quiteness.

Thanks for giving me the hint I will make an r&d on FFT.
but how could I know the audible limit of the sound wave file as the header donot contain this info.
I didnot used any API ,I am provided with the wave files recorded from a
software in PCM,16000kHz,1 channel mono,16 bit sample unit.
thanks

even i require some guidance on this problem.
hope my question may give you some idea on how to achieve this.
iam able to read each sample in binary format from the wave file.
now can you let me know, if i can understand from the sample packet, if there is a silence or any audible wave form in that?
killabyte wrote: otherwise you could FFT analyse the buffer to see if there exsists a freq in the audiable spectrum range with a magnitude of X, where X is your tolerance of quiteness
can you explain this a bit clearly?
if FFT, is going to solve this problem for me,
then please give me some guidance and justification.
i remember, i wrote some algorithm to find FFT long long ago.
thank you.

hmm where to begin... it really depends on your level of knowledge of DSP. i dont profess to be an expert but i have played around with matlab a fair bit mainly to analyse the data from a sensor i had and create a series of FIR filters accordingly.
i had assumed(DANGEROUS) that u will be reading in a file or streaming data in, and then analysing a small bit of this file/stream in a buffer.
so the raw data u have in the buffer is basically magnitude on the y axis and time on the x
(time is just the sample count normally).
once you have FFT'ed the buffer you now have a magnitude on the y axis and a freq on the x
you can then say if i dont have a magnitude of 'somevalue' in a freq range then i shall flag this as silence. and chop my file here.
this is a really simple overview, hope it helps.

really gives me some clue,
but still...
some more work around has to be done.
now, i have a sample, in an array of 2239 bytes for example.
(this sample is obtainied from the wav file by reading the bytespersample field from its header).
now, the concept of magnitude in connection with this binary is clearly not understood.
could you emphasise a bit more on this?
thanks again.

ok it sounds like your reading in the whole file so doing an FFT on this wont enable you to determine a position of the silence. (because u have no time reference anymore, but if your buffer size was small enough chunk then you could).
if your dealing with PCM data ( i think you 3 are the same person?) then you could just parse through the array looking for a series of zero value +/- a tolerance ,remembering that zero might be different according to your encoding IE. if the data type is signed or unsigned the zero value or centre point will be different (8bit signed zero pt = 0, 8bit unsigned zero point = 128).

but i observed a fully silent wave file(a wave file which is recorded with no input audio), i did not find 0 s there.

so u had backround noise or you are using unsigned data encoding.
was the data obsevred about 32000?

thanks for your concern.
i will revise it once again and give you the correct details.
please give me some time.

here is some information i can provide you.
I read the header of a wave file and is as follows.
bytes per sample-2
bytes per second-44100
samplesrate-22050
in the data chunk, the data is as follows
99 FE,97 FE,99 FE,97 FE,94 FE,95 FE,97 FE,97 FE,-----
means, 2 bytes per sample, so can you suggest something from here.
NOTE: this is from a file that is recorded by un plugging the audio jack, means, the file is fully silent.

Hi,
i have a doubt in a dialog based application created in vc++...
Whenever we create a dialog based application, if we press Esc Key, its getting closed... i dont want it to be closed ....
is it possible to do that??
Thanks,
Rakesh.

Rather than me answering this question I would suggest you to read here[^] and here[^]. And if this doesn't help then try this[^]
You need to google first, if you have "It's urgent please" mentioned in your question.

Which will prevent the dialog from being closed while the cancel button is clicked as well. The previous answer given to the OP was better.

dear sir
i need a high speed method to make 4 image from one, that the first image have for example 2048*1536 pixel, and the four made is each 1024*768 , so i use the getpixel and setpixel method that is too slow :
vb.net code ::
For y = 0 To picy.Height - 1 Step 2
For x = 0 To picy.Width - 1 Step 2
pic(0).SetPixel(Int(x / 2), Int(y / 2), picy.GetPixel(x, y))
pic(1).SetPixel(Int(x / 2), Int(y / 2), picy.GetPixel(x + 1, y))
pic(2).SetPixel(Int(x / 2), Int(y / 2), picy.GetPixel(x + 1, y + 1))
pic(3).SetPixel(Int(x / 2), Int(y / 2), picy.GetPixel(x, y + 1))
Next x
Next y
please help me to find a very faster method in any languages, vc++ or vb or vc# or others , its not important i need a fast method,
thank you for attentions and cooperations.
