There are many plug-ins which will do compression in real-time (with the attendant increase in CPU usage during playback) if you really want everything to be at a similar level. This post is too long already to discuss compression in depth, but briefly - this does alter the dynamic range of the music you're listening too, increasing the volume of the quiet sections and reducing the volume of the louder sections. If that's a problem for you then you need to look beyond normalisation to compression. The disadvantages are as discussed above, and as you've discovered - tracks will often still sound "unbalanced" when levelled this way. There are reasons and benefits for managing volume this way: 1) it's non-destructive, 2) it requires little processing power during playback, and 3) it leaves the dynamic range of the track as the artist intended. It doesn't change the volume within a track (it doesn't "alter the dynamic range"), so a quiet song with a very loud crescendo at the end will still be played quietly most of the way through, and will sound quiet compared to a track that's loud all the way through - the only thing you can guarantee is that the loudest points of both tracks will be equal. Later, when playing tracks, it retrieves that value, looks at the setting for "Target volume level for Playback", calculates whether it needs to turn up or turn down the volume in order that the loudest point is played at your chosen level and off it goes. It then calculates how much louder, or quieter that is than a notional "zero" point, and writes that calculation in a tag. This means that the system runs through each file, finds the loudest point in that file (or that album, if you use album mode). Volume levelling, as used by MM3 (and the iPod's Soundcheck function) is "normalisation", not "compression". What you may be doing wrong is misunderstanding what "volume levelling" is. Genegraham wrote:So.what am I doing wrong, if anything? I'd think it would whip through the collection pretty quickly if it just looked at the "Track Volume" tag and saw a value there. As a bonus oddity, when I tell it to "Analyze Volume" it goes through each track very carefully, apparently analyzing the volume of each track even though I've told only to analyze tracks with unknown volume. When it was through, the "Track Volume" tag has values ranging from -11.2 dB to +18.8 dB.Įven after the process was done, it doesn't seem like the tracks are very well leveled. When I ran the "Level Track Volume" routine (Tools ->v Level Track Volume) it took a couple of hours for MM3 to go through my 3000+ library. Under Tools -> Options -> Volume Leveling I have the "per Track" option selected, along with "Only analyze Tracks with unknown Leveling Adjustment," "When analyzing Track volume, also analyze Album volume," and "Automatically analyze volume of unanalyzed tracks." So, I've got one hand on my iPod volume all the time, twiddling it to turn some tunes up and some down. The tracks are still, to my ear, very unlevel. I've tried to level the volume of my library. further changes are very fast.My first attempt at this question had a couple of replies and I think folks might have thought my questions were answered.they were only partly answered. Note: the first pass on a file can take some time because of the first statistical analysis. An option allow to automatically lower gain to not clip audio! so you can boost the volume as max as you can without quality lose. This app can boost the volume of your music or other MP3 files several times louder. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding. Also, the changes MP3Gain makes areĬompletely lossless. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. MP3 Gain does not just do peak normalization, as many normalizers do. The volume of your prefered song is not loud enough even with your phone's volume set to maximum? So use MP3Gain to amplify your song! it's very easy. MP3Gain helps you to boost the volume of your mp3s
