Maybe this would a lot easier to fix with the De-esser plugin but I don't know how to remove the thuds with it .

My bad: I meant the De-Esser's sibling plugin De-Clicker can be used to de-thud ...

OK, I watched the videos and studied what you've shared with me. I get a general idea but I'm not able to fix it myself. I don't know what's the frequency of the sounds I want to remove and I think I can see the thuds in the spectogram but I don't get what tool to use or how. I tried the notch filter and the spectral multi-tool but I don't know how to set them, so that didn't work. I also wasn't able to use center snaping. Paul Licameli makes it look SO easy !

Sorry if I'm being a pain. Like princess Leia said a long time ago: "You're my only hope." Can you Mike, Trebor, and the rest of you gals/guys, please tinker with my file and give me some more details about what to do ?

This is the spectral edit tool in action ...

The vertical lines are clicks & thuds.

Thank youTrebor. OK, I was able to do something using the spectral delete effect. The thud turned into a low volume bleep. I'll call that a step forward .

I could also try the De-clicker plugin but I get lost and intimidated with all the number fields. I tried copying the numbers shown by Trebor on his image from June 18, but the thuds didn't go away after I used it. Can anyone please give it a try on my short file and tell me with what numbers it will remove the thuds?

Thank you all.

EDIT: What?! I think I got it ! I was able to remove a thud paying closer attention to the white color and using the spectral multitool. I'll keep on practicing, but I still appreciate help with the De-clicker just to learn .

I thought I had it. I was able to remove the thuds from the small audio file I had shared with you before, but when I tried it on the original file, the spectral image actually looked somewhat different. In that one, I was only able to turn the thuds into softer bleeps.

I'm attaching two screenshots showing more or less were the thuds are. These are prior to any editing. Can you please help me with the following? To what frequencies and colors should I be paying attention to regarding the thuds?





Getting closer and learning a little bit .

... To what frequencies and colors should I be paying attention to regarding the thuds?...

Plosive thud's are mostly below 300Hz.
Attenuate them until they match into the background colour, whatever that colour is.

It may be quicker just to re-record with a pop-shield,
and/or put the microphone to one side to avoid blowing on it, which is what causes the thuds.

re-recording would be quicker than repairing ...

Gerardo,

Here is what I have come up with. The noises are reduced, definitely not completely, and the editing probably negatively impacted overall audio quality. But I did not spend a lot of time to get a more precise fix. If you wanted to try multiple fixes on different areas, you could probably narrow it down to a better quality. Also, if you zoom in closer to the bad sections of the audio, you can get the rectangular selection area of the Spectral Edit Multi Tool to fit better into angled areas to clear them up.

My settings for the Spectogram are as follows as I think it gives a clearer picture of the areas in the wave that need repair:



Here are the effects I used:

1 - Filter Curve – 100 Hz Rumble – on the whole audio.

2 - Highlight the area to fix and use Effect > Nyquist > Spectral Edit Multi Tool – you may need to use it multiple times on the same spot. On the click noise, I only used the Multi Tool once and on the Thuds, I used it multiple times. I tried to clean up in between the horizontal white frequency bands on the Thuds and get rid of any other white band residue that was present. I applied the Spectral Edit Multi Tool until the color changed from white to purple/blue since white represents the loudest sound and blue/gray are the quietest sounds.

3 – I Ran Filter Curve – 100 Hz Rumble again.

The repaired areas are circled in blue below and I included a copy of the repaired audio for you to listen to.

Good Luck.

Mike

Thank you Mike and trebor all this has allowed me to learn more about thuds and the spectral view. I'm tempted on recording everything once again. At least now I know what I did wrong and have an idea of how to attenuate those thuds if they aren't too loud.

I really appreciate it all. Thank you both.
