Hi All,


I have two wave files which I need to compare, both file has the same audio
on them but recorded differently (noises at the background, different
volume, silence gaps and so on)



If you listen to it you can tell it is the same audio easily,



I need away to get the similarity between this two files.



I am looking for a code, ideas, activeX dll, C library or anything else that
can help me accomplish it.



Thanks,



Avi

What kind of audio? Music, speech?

Are the frequencies the same? You mention different volume, different
silence gaps, etc.

You could do FFT's (I believe) to get frequencies, then line up the similar
frequency peaks.

There are plenty of fourier transform algorithms out there.

What do you expect to be the result of the comparison?

What legitimate use is there for this program? (I can think of non-legit
reasons for it...)

The frequencies are the same, it is the same file which was recorded in a
different way, it could be speech it could be music, the use is for
automatic debugging purposes of a voice response systems.

Thanks,

Rufus,

Where can I find stuff to be used with VB6?

TIA,
