Well, maybe it’s a popular thing, but everytime when i save my project ( i mean when i convert it to mp3 )
there is a large decibel increase, like 30 Dbs up, it happens to me everytime.
I couldn’t find anything to solve this. At least send me a link where i can solve this.
It’s really frustrating bcs i can’t make it to previous condition…
Please help, thanks 
there is a large decibel increase, like 30 Dbs up, it happens to me everytime.
How are you measuring that? Does it sound badly distorted? A “normal” recording increased by 30dB would be be “unlistenable”.
Are you applying any effects, or mixing, etc? Does this happen if you just open a file and export to MP3?
What happens when you export to WAV?
It’s not unusual for the peaks to increase by 1 or 2 dB with MP3 but it shouldn’t sound louder… MP3 is lossy compression. The wave shapes change and some peaks increase while others decrease. MP3 is not hard-limited like regular-integer WAV files and it can go above 0dB without clipping.
Well, it is distorted. Yeah, i used some effects and i turn up decibels like +6 but then i convert it and buum, it sounds like +60.
I can show you on video how it happens. And this happens to me everytime, no matter what if i use effect or not.
You’ll need to tell us exactly what you are doing because Audacity does not do that for us.
Which version of Audacity are you using (look in “Help > About Audacity”). Did you download it from us (http://www.audacity.audio/download/) or from a 3rd party site?
Which version of Windows?
It says 2.1.2 and i don’t know where do i have this but i’m sure not from you.
And also i hadn’t this problem before. It happend just all sudden and it really pisses me of.
When i save project decibels goes up, then i have to low decibels with the switch at left side and i make it like -20 Dbs.
Then it’s listenable. I mean it’s good condition but still when i have a lot of tracks i have to do that to every single track.
i’m sure not from you.
Audacity is open source software, so anybody could offer their own version with their own tools and custom services.
So you’re asking us to trouble shoot somebody else’s software…
This is ours.
If you install it over an old version, remove the old version as much as possible and check Reset Preferences during installation.

1. As the last step before exporting to MP3, run the Amplify effect and accept the default.* That will set your peaks at 0dB. (If your peaks are below 0dB, Amplify will default to a positive gain. If your peaks are above 0dB, Amplify will default to a negative gain, bringing your peaks “safely” down to 0dB.)
2. Open the MP3 and run Amplify again and note the new default. You can cancel the effect without making the change.
3. If Amplify now defaults to -2dB, that indicates that the MP3 encoding has boosted the highest peak by 2dB and your peak is now +2dB. Like I said, that’s normal. If Amplify defaults to -30 or -60db, then you’re right… Somehow the level is being boosted and you’ve got a big problem.
And if you are getting the “accidental” 30-60dB boost, try the experiment again but export to WAV. If WAV works without boosting the level, you can try re-installing LAME, or just use a different MP3 encoder.
Yeah, i used some effects and i turn up decibels like +6 but
If you’re working with commercial songs, most commercial releases are already normalized (maximized) so you can’t boost the volume or boost with EQ, etc., without clipping.

- Any time you do anything that boosts the volume, it’s a good idea to run Amplify to check the levels before exporting. If the the peaks are above 0dB (if Amplify defaults to a negative gain) you should go-ahead and run Amplify to bring the levels down. If Amplify defaults to a positive gain (meaning you still have some headroom) you can cancel the effect if you don’t want to change the volume.
P.S.
when i save my project ( i mean when i convert it to mp3 )…
…Yeah, i used some effects and i turn up decibels like +6 but then i convert it
Diagnosis, debugging, or troubleshooting is a process of elimination. You’re thinking it’s the MP3 conversion, so try a WAV file… Try an MP3 without turning-up the level or the other effects. One thing at a time, 'till you find the cause.
If you have multiple Audacity tracks on top of each other as you seem to be saying, that’s the explanation, because the volume of the tracks adds together (the more different the tracks are to each other, the less the volume increases).
If that’s the problem, yes, move the -…+ gain slider on each track leftwards until the playback meter does not show the red clipping indicator. Audacity does not calculate for you so that the combined mix does not clip, but you can ask for it as a feature request. Or as long as the tracks say 32-bit float, you can Tracks > Mix and Render and then Amplify > OK as Doug described.
