Hi all,

Im in the process of developing a voice compression method. The method i intend to use is after sampling a voice signal dividing it in to frames and getting FFT. then zero out some random frequencies inorder to achieve compression.

But im stuck at few points. What is the proper way to sample a voice signal at a sampling rate of 8000Hz.? Then how can I zero out some random frequencies?

Can you pls help me with this.

Thanks a lot..
