Anyone good with audio editing?

Vampyromaniac · Mar 15, 2003, 08:32 AM

I've got a little problem . . . it's a glitch in a song, and I just don't know how to get rid of it.
Of course, I probably don't have all the skills or the tools, hopefully someone here can help me out.

The glitch sounds sort of like some static . . . I can't describe it well.
But, here is a 2-second clip, as an example of the glitch: glitch.wav (344 KB)

In that file, the glitch occurs a little more than 1 second into it, in the right channel, right before the big beat at the end.

Any help is appreciated

Audio editing can lower the quality of the sound in a music file. Are you sure you don't want to just download/find a good version instead of trying to fix this one?

Necrosis · Mar 16, 2003, 11:09 PM

Sound Forge 6 is non destructive.

However, what needs to be known is what format is this coming from? It could be harmonic distortion or a limitation or defect occuring at the recording source of the audio. To me it almost sounds like some kind of effect reverbing.

Vampyromaniac · Mar 17, 2003, 07:34 AM

sweet, my 2 fave audiophilez replied

About quality degradation, yeah I was hoping for a way that wouldn't be too noticeable (tried smoothing thru EAC, it sucked)

The source of the song was from a CD, extracted by EAC, with 0 errors reported . . . I have since given the CD back (it was borrowed,) or I of course would play the CD again (digitally thru IDE), to see if it's OK there, and re-extract if so.

I was in the process of reviewing the .WAV's to make sure they were good, before making my CD's, and found that glitch (it occurs a few times actually.) I didn't think I'd find anything, let alone something so hard to fix

"harmonic distortion or a limitation or defect occuring at the recording source of the audio" . . . you mean when the song was actually recorded, right? Yeah, I wish I still had the CD

Do you have experience with Sound Forge? Do you think it might be able to clean it up?

Oooh, has anyone tried monkeying with the clip to see what can be done?

EDIT: If there's ANY info anyone might need from me to help figure this out, feel free to ask !

Vampyromaniac · Mar 25, 2003, 11:29 AM

no ideas?

I was hoping someone knew a magic trick that would take care of this

I have experience with Sound Forge 5 & 6. I haven't tried messing around with the file because I've been working on getting my new setup going. Hopefully I'll have some time here soon and take a crack at it for you.

Vampyromaniac · Mar 25, 2003, 10:24 PM

Ah, thank you so much!

nmpaulcp · Apr 4, 2003, 09:22 AM

Hello,
New here and can hear the glitch. Don't have any idea what it is but if it bothers you,( it would bother me ) . I would try a transient noise filter, and if that didnt work I would cut and paste a section frorn another part of the song that is real close, I have done it with transient noise and it was unnoticable.

Vampyromaniac · Apr 5, 2003, 05:35 AM

Hi and thanks for helping out on your first post

What programs do you know of, would have this transient noise filter available?
(eg. SoundForge ?)

nmpaulcp · Apr 5, 2003, 07:31 AM

Thanks for the welcome. I use a program called "diamondcut 32" from "enhancedaudio" They have another company that markets their products
Tracertek.com. They have a free working version that you can use for ten days this should get you there. http://www.tracertek.com/diamond1.htm. Good luck finding it. Scroll to find the trial working download. I use it for restoring vinyl which is what it is made for, but it has a full range of filters, and cut and paste functions. Lots of good stuff. They have alot of other excellent programs also.
I can to this forum to find info on the kt audio driver.

nmpaulcp · Apr 5, 2003, 07:34 AM

remove the period after "htm" if you cut and paste the shortcut !

Joneser · Apr 5, 2003, 08:00 PM

Sometimes just simply raising the threshold level of the noise floor will help.

Thanks, I'm downloading it now

I'll give it a shot and see how it goes!

Vampyromaniac · Apr 24, 2003, 03:03 AM

Well, I tried the diamondcut 32 software, and it did remove the glitch from my little clip . . .
But, when I tried it on the actual song, it left a noticeable click at the beginning and end of the edited parts
I could apply the filter to the entire song, but it degrades the sound quality.
I guess I'll just have to live with that little annoying glitch

nmpaulcp · Apr 24, 2003, 03:18 PM

Instead of using the transient noise filter you could try and replace the bad area (magnify and find the exact location) and replace it. Find another area of wave form that looks very similar and raplace with copy/paste over . Look in the help files on pasting. I have repaire many bad areas of a wave form like that. the actual glich is only a few thousandths long you will never notice it !

Vampyromaniac · Apr 25, 2003, 09:40 AM

It's actually a unique part of the song, it never gets repeated

Btw, there was no "transient" noise filter, the one I used was "dynamic" noise filter

nmpaulcp · Apr 27, 2003, 04:58 PM

If that is the only copy you have of the file I would just copy and paste over, find a similar area when you magnify the wave file. and copy paste, there are adjustments on that also. read the help files on copy/pasteover. The glitch is probably only a few milliseconds long and if you can eliminate the spike you will not notice it. I've done it many times restoring vinyl. try that without using the filters.
ps you are right its a dynamic noise filter , it removes transient noise. My bad

Vampyromaniac · Apr 29, 2003, 04:29 AM

Hmm I think we are not thinking of the same glitch

I think you're referring to the little speck at around 0.50 seconds

I am talking about a short period of a "soft static" sound lasting maybe 300 milliseconds.
Somewhere in the vicinity of 1.200 - 1.500 second mark, only in the right-hand channel.
I've cropped it to show only the glitch, here: glitch-crop.wav

Now I understand you were suggesting copying a tiny snip of waveform, but this is around 300ms,
that's why I was saying I can't, because a section that long doesn't get repeated anywhere . . .
But, based on your suggestion, I tried something similar, which provides a decent workaround.
I copied and pasted the left channel over the right: glitch-fix.wav
Sure, the song turns "mono" for a brief moment, but it's not too noticeable,
and at least that staticy sound is gone.

Joneser, in response to your previous post, I did try a noise gate, to no avail

And, also thank you for your other effort to help

Vampyromaniac · Apr 29, 2003, 08:38 AM

OK, here is the file again, now I believe it has no glitches at all.
glitch-free.wav

Have a listen, and see if you can hear anything (aside from the brief lapse into "mono"),
especially if you have good speakers & soundcard

I can't hear any glitches/pops/scratches/static, but then again, I've heard this clip about 1000 times, and I need some sleep
