Is there any possibility to remove the echo in my audio recording (
seehear short example on soundcloud)? How?
The audio recording is from a Skype session. The echo is very bad, but also quite special: one single and loud repeat of the audio signal after about 0.2 seconds. So I hope there might be a possibility to remove the echo (or improve the understanding in some other way).
I searched this and other websites for a solution (e.g. How do I make my voice not echo in audacity?), but did not find a cheap solution. I am willing to pay some money for getting a cheap tool or getting the recording fixed, but do not want to pay a lot for a tool I then only use once. I did try noise reduction in audacity, as well as the following de-echo nyquist script, but with no improvement :(
;nyquist plug-in ;version 1 ;type process ;name “DeEcho…” ;action “Removing Echo…” ;info “This effect removes an echo.” ;control decay “Decay” real “%” 50.0 0.0 100.0 ;control delay “Delay” real “seconds” 1.0 0.001 10.0 (defun de-echo (s decay delay n) (cond ((= n 0) s) ((oddp n) (diff (de-echo s decay delay (- n 1)) (prod (expt (/ decay 100.0) (float n)) (at-abs (* delay n) (cue s))))) (t (sum (de-echo s decay delay (- n 1)) (prod (expt (/ decay 100.0) (float n)) (at-abs (* delay n) (cue s))))))) (de-echo s decay delay 10)
