Hello, I am new… I am using Win7 and the latest audacity 2.4.2
I want to increase the volume on some mp3 (and also flac) musictracks, but I seem not to be able to actually find anything…
What am I doing wrong?
Thanks
There is a digital limit on how loud things can get. Are you trying to match something?

Have you tried the Amplify effect?
…Most commercial music is already normalized (maximized). But that doesn’t mean they all sound equally loud. And, many MP3s go slightly over the “digital maximum” of 0dB, so the Amplify effect may default to a slight attenuation.
Thanks for your answers. First of all, I make my own playlists and so some music is already loud, and some is not. Plus, I listen to podcasts, and there also some are 82db and some are 95db, which is what I want to use. Try listening to a voice at 82dbm when you walk next to trafiic…
What I am looking for is a software, where i take a folder with 20 songs of all kinds of volume, and change all of them to 95db.
Can audacity do that?
Hi Rossdorn:
I’m also on the same boat with you, I have some MP3 songs that I’ve saved to my PC but it seems like some of the the songs, when played back do not have the same volume level, some are loud and some are very low which I can barely hear the songs when played. I was wondering if you’ve found a solutions to it , maybe you can share it with me as to how you’re able to make all the music sond at the same level. I would greatly appreciate that.

I assume you are using MP3Gain or ReplayGain?
Those are NOT dBm they are dB SPL (acoustic sound pressure level = sound loudness in the air) and they are NOT actual levels. The acoustic volume depends on your volume control, amplifier power, how close you are to the speakers, etc. The acoustic reference of 0dB SPL is approximately the quietest sound that can be heard so SPL levels are positive.
Digital levels are measured in dBFS (decibels full scale) where the 0db reference is the “digital maximum”. i.e. It’s the highest you can “count to” with a given number of bits so dBFS values are usually negative.
There is a perceived loudness standard for digital files ([u]dB LUFS / EBU R128)[/u] which is a kind of average that takes the [u]Equal Loudness Curves[/u] into account. These are also negative values.
ReplayGain and MP3Gain are similar to LUFS with some assumptions about the relationship to acoustic loudness, and that’s how they get positive dB values.
What I am looking for is a software, where i take a folder with 20 songs of all kinds of volume, and change all of them to 95db.
The problem is… Many songs, including quiet-sounding songs are already normalized/maximized. ReplayGain uses a lower target volume so it can lower the louder songs rather than boost the quiet songs. (Even so, a few songs will remain too quiet… The default 89dB target It’s a compromise.)
With MP3Gain at 95dB you can allow clipping (allow distortion) and the quiet songs will be boosted. If you don’t allow clipping many songs will be un-touched, or they won’t be adjusted fully-up to that 95dB target.
There is something else you can do… The [u]Limiter[/u] or [u]Compressor[/u] (when used with make-up gain) can bring-up the overall/average volume without clipping the peaks. However, this reduces the dynamic contrast (trending all of the sound toward the same volume) which can make music boring and it can have other side-effects.
