Hi,
I am trying to reduce the noise in a .wav file output while it is played by the system. Based on the Article by Jeff Morton ( Sound Activated Recorder with Spectrogram, I am able to get the spectrogram and Frequency Domain display. However, the picture box which displays the frequency domain content blank off frequently. Can unsafe code cause such a behavior?
Can anyone help me?

I told you yesterday, if you think unsafe code can cause this, you know next to nothing about C#, and should read some books or do a course. Why are you asking the same question again ? An intelligent person would consider posting some code so we can see what is going on, instead of asking a question they have the answer to already. You also need to define 'blank off'. It's obvious your code is causing this, but is it flickering, or is it going blank for long periods. If it's flickering, that's just a lack of buffering. If it goes blank, then work out why your code does that.
