Frequency wave

[rainny]

I am creating an application which is when load the speech, it will
appear the frequency wave. So that, we can know that when a person is
speaking, got waveform appear while nobody is speaking, there are no
waveform appear.

Anybody have any suggestion on doing it?

rainny,

Each time you post you start with such a general question that
it always takes several posts to narrow down what exactly you want.

So I'll start the ball rolling.

Java Sound API

Ya, first what I try to do is not clear about the requirement. Now, I
understand the requirement already, so I find towards the best
solution on solving the problem.

Anyway, thanks for your kindly reply.

This may be more than what you're looking for.

Just now, I find out one algorithm which is call Fast Fourier
Transform( FFT). It is stated that this algorithm can applied inside
the speech application and can detect the frequency if the sound data.
may I know that does anybody know how to integrate the speech
application with this algorithm?

Hope can get the reply soon.

Thanks and regards
Rainny

Look in the "Fun With Java" subsection.

google "fast Fourier transform"

Hi, i try to search google about fast fourier transform. But, i unable
find how it is use in the java speech application?

Anybody have any suggestion on it?

Thanks for all kindly reply.
