I am using 2.0.5 version of audacity. After editing a set of vocals I export multiple to wav. Prior to this when reviewing each vocal in edit mode the vocal sounds great however after the export there is a buzz noice added to each vocal. This just started happening when I added this version to my new computer. Anyone have a clue why this is happening?
Is this “buzz” constantly in the background, or is it like distortion and only buzzing when the voice is loud?
What kind of editing are you doing? Any effects?
I’m editing a voice over for a eLearning project. The buzz is just showing up at the beginning where I have 0.5 of silance. I also notice that if I open up the wav file and edit out the buzz then choose export selection to wav the buzz does not show up again.
Also I’m not using any effects.
Sorry, I don’t have any idea why that would happen. Normally, silence remains silent and Audacity doesn’t “acciently” add or change anything.
Normally, noise is an analog problem.
In any case, I’m happy to hear you can edit-out the noise.
Select a portion with noise in it and post it here.

Attached is an example of what is happening. In Audacity the buzz at the beginning is not there.
Try generating 5 seconds of silence (“Generate” menu), then export as a WAV file. Does that have the noise?
The first time I export a vocal the buzz is added in during the export process. If I edit/silance the buzz and export it again the vocal sounds great (no buzz/noise is added 2nd time around). This is what I have been doing however when I have hundreds of vocals to edit this duplicate is causing extra work and time. I can’t figure out why the buzz happens the first time and not the sencond.
Actually, you said something there. If you export exactly the same thing first and second times, do you get the buzz on both? That is, Export a clean show once and then export again immediately under a slightly different filename. Do Not Change Anything Else.
If the second one is clean, that should save a bunch of time short of solving the real problem.

There’s nothing magic about the sound. It’s mostly pink noise with a little 60Hz and related hum in there (but not much). Are you in the US or on US power?
The universal instruction when you have oddball problems is restart the machine. Have you?

The first time I export multiple vocals at once using the orginal edited vocals. The second time I edit the WAV file. I did try to export the orginals twice but the issus still exists.
You exported the original work twice and got the same problem on each export… Um…
That suggests the problem is arriving on one of your sound clips. It’s rough to believe that Audacity is making it up. When Audacity makes mistakes, it’s more of a fire and brimstone thing.
The brute force method is to Mute half of your clips (on the left of each clip) and export the show. Then Mute the other half and export to a second file. I bet one of the files is right.

and it’s very strange that there are no other reports of this problem, and we are not able to reproduce it.
If we are to make headway solving the problem I think you will need to give us step by step instructions so that we can produce the problem. Start with “1) Launch Audacity from the Desktop icon” (or whatever method you use to launch Audacity.) If we can reproduce the problem then there’s an excellent chance we can solve it.
Still no answer to my question: https://forum.audacityteam.org/t/buzz-noise-at-beginning-of-vocal-after-you-export/34571/8
Also, have you tried resetting Audacity preferences yet? If not, please do so, then test. To reset preferences, re-run the Audacity installer and select the option to reset preferences when it comes up, then confirm resetting preferences on first launch.
Yes the buzz still is showing up.
Please use more words. If we ask you to do something, say you’ve done it, so we know.
Have you reset Preferences?
Have you generated a tone (Generate > Tone…, I suggest at amplitude 0.2 so it is not too loud), exported it as WAV, and does the WAV have the buzz?
Are you only hearing the buzz when you listen in a particular playback device or only when you use particular headphones or speakers?

Not yet, I need IT approval at my agency. As soon as I get it I will.

There is no buzz on the WAV file.

I only hear the buzz on the WAV file after the export. It does not show in the audacity file. The buzz appears on both my laptop (version 2.0.5) and desktop (version 2.0.4). I have also switched our my head phones.

Have you restarted your computer?
Yes
My experience - I have been using Audacity for about two years and this is the first time I have experince this issue.
Try generating 5 seconds of silence (“Generate” menu), then export as a WAV file. Does that have the noise?
No noice on 4 second of silance.

- Launch Audacity from the desktop icon
- Record narration for eLearning (I usually do about 10 tracks per file, and a training usually has about 100 tracks.)
- Edit out coughs, um’s, silence about 5 seconds of the beginning of each track/rename Audacity tracks (at this point there is no buzz/noise at the beginning. I have about 5 second of silence before the vocal starts.)
- Save Audacity file on our agency network
- Unmute all tracks
- I export multiple tracks to WAV.
- When I open the WAV file in Audacity you can see and hear the buzz.
- What I’ve been doing is editing out the buzz and then exporting each track individually using Export Selection. (This works, but is causing duplicate work. I would like to eliminate steps 7 & 8)
