Bonjour. I have an signal(rough.wav) which is impulse response of a system. The impulse response should ideally be like smooth.wav .i.e. A smooth damped harmonic oscillation. Please tell me how to filter rough.wav to get smooth.wav , Both these files are in signals.zip in the files saction of this forum. |

hi, This is very simple. U can use adaptive filtering i.e. LMS algorithm to filter any noise out of signal. Use the adaptive line enhancement configuration and get the result regards kiran --- "Muhammad Shahid Munir <>" <> wrote: > Bonjour.
