overlap and add

[Srinkoo]

Hello,

 I have been going through the overlap and add VI. I am wondering about the output i.e; filtered data and overlap data. When we are sending the sound file how are we getting the output. I mean what does it suggest. Can anyone explain me the output.

See the explanation here

I read this. But I could not get it. I could not understand why the waveforms are behaving like that.

Can you give some details?

when am running the VI, lets say chime.wav is loaded and run, the filtered graph and overlap add graph show some waves going. Can you explain the behaviour of the waves in graph.

Hi Srinkoo,

If you need more information about the overlap and add algorithm, poke around the internet. It's an algorithm that basically performs a discrete convolution of two signals. If you're familiar with signal processing, then you may get some milage out of the wikipedia article on it. If you are not familiar with using DSP, this is probably not a tool that will be very helpful to you. Is there some task you are trying to accomplish that this is addressing?
