EZ-Patch Double Note [SOLVED]


I posted for the first time recently about click removal, and managed to remove all the problems, except for four pops. I have been trying to use the EZ=Patch plugin by Steve Daulton on those four. I have been following the enclosed link https://forum.audacityteam.org/t/ez-patch/22093/1 but each time I select an area I am getting a double or repeat note or chord replacing the pop, regardless of whether I chose the before or after setting. Each pop is about 0.3 of a second when zoomed in. They are too long for Pencil Tool or Repair Tool, and i am not skilled enough to do it by Spec’ editing despite the wonderful Youtube video by PaulL. I would be grateful for any help. Thanks.
PS I have tried Notch Filter in bothe Audacity and REAEQ, but cant get it exact. :confused:

Could you post a short audio sample of the problem. About 5 seconds in WAV format with the click somewhere near the middle. See here for how to poat an audio sample: https://forum.audacityteam.org/t/how-to-post-an-audio-sample/29851/1

Thanks for the quick reply Steve. In the enclosed sample I have a couple of bits of mud at about two and four seconds. There are a couple of other examples on the whole track, but I have solved everything else. I think I am on the right lines with EZ-Patch, any improvements on this idea would be gratefully received. Thanks.

It sounds as if you have already attempted a repair in those places. Do you still have the original unedited version of that part?

Thanks for the quick reply Steve. I am guilty as charged, I did run a repair on it before presenting it. I ran PaulL’s De-Clicker on it. I was only left with four bits of mud sounding data. The rest was passable and just needed some filter work, and equalising. I could have done the first click in the demo wav manually which was easy enough. The second one however was in the original which I have supplied. It is too long for Pencil Tool or Repair Tool, which is why I was looking at EZ-Patch. The guitar work is too intricate, it sticks out like a sore thumb if I do a delete. I am not skilled enough yet for Fade in and Fade Out manually after a delete.Any help or suggestions would be wonderful. Thanks again. :slight_smile:

The damage is mostly in the left channel, so it is possible to make a pretty good repair using the “Repair Channel” effect: http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Repair_Channel

Tip: use the Spectrogram view to “see” the damage. http://manual.audacityteam.org/o/man/audio_track_dropdown_menu.html#spgram

Tip 2; where possible, avoid making the crossfade over the “attack” of a note - the blends will generally be less noticeable during the decay of the notes.

Thanks so much Steve for your help and excellent fix, this is now solved. The Repair Channel add on is a wonderful addition, and has saved me so much time. Thanks again. :slight_smile:

I’ve done a fair bit of “audio restoration” and it’s always a challenge. i tend to be quite wary of restoration effects that are applies to the entire track - always keep a backup!

One useful technique is to duplicate the original track (select the track the Ctrl+D), mute the original track, and work on the duplicate. If you produce a “bad bit” in the duplicate track, you will probably be able to cut and paste from the original onto your “repaired” track to “revert” the bad bits back to the original.
