“Modify Gain” -> “Undo Gain Changes” Step 1 … as you can see in ‘Red”, it indicates that the file has gained volume levels previously …ģ. First locate the file or folder and load it to QMP3Gain’s main window. How to “Undo” a previously gained volume level?ġ. If interested, you can get it from this QMP3Gain project home page. These are just some of its main features to mention. As said, you can always Undo your changes whenever you want (it’s completely independent of the program as you can even uninstall QMP3Gain and re-install it again, then load a previously changed audio file, and you should still see its original volume levels). So use it with caution.īy default it’s disabled and most of us would want to keep it that way as it wouldn’t change anything in the meta-tags (holds information such as Artist, Title, Album, Year, Genre etc). However it might corrupt the track while doing so as well. So you can use this option to skip those errors and change the volumes. This can be both useful and could also be dangerous.įor instance, if you have tracks with some issues (with meta-data not 100% accurate or issues with the header file etc), then QMP3Gain might not let you adjust the volume levels by default. It has an option called “No Check for Layer i o ii” which skips quality checking before applying volume levels. Gain volume per track or for an entire album. An analysis tool that shows the default volume levels or gained volume levels (if you’ve done so already). I like “QMP3Gain” over the “MP3Gain” because (the features and UI designs are almost the same), QMP3Gain is written in Qt4 and looks modern □ where MP3Gain is a bit of an old tool which might not look that pretty if you use it with never Windows versions such as Vista and 7. Or it can be used with few other volume gaining back-ends as well. QMP3Gain is actually a Qt written (open-source user interface builder) front-end that uses a very popular tool called “MP3Gain”. So in that sense, if you’ve been searching for a free utility that lets you adjust audio levels (both single and batch file processing) with ease, then QMP3Gain is a tool that you should try. So it’s pretty darn important that we have the ability to rollback the changes whenever we want. So it’s pretty safe.Īnd the reason I wrote about that is, depending on the file and its content, let’s say that after gaining volume to somewhat higher decibel levels (dB), it can sometimes create audio distortions. This is done by simply adding a volume level field in the file’s “header” (this is a special location in a file that holds key information such as the codec that should be used to decode the content, file size, duration etc). Meaning that, you can always undo the changes and get the original volume levels back. This is useful because, there are some encoded music files (sometimes happen when downgrading from a high quality multichannel track to 2 channels stereo or when changing between audio codecs) that have either low or too high volumes by default.īut the good thing about volume normalization is that, most tools (including the one that I’m writing here) do it in a way that it’s 100% lossless. Load the MP3 files, click on the analyze button in the programs menu.Audio volume gaining or normalization is the process of adjusting the audio level of an audio file (increasing/decreasing) and saving the changes permanently (so you don’t have to manually up/down the volume every time you play a track). You can analyze and normalize a single file or multiple files or even a folder with your MP3 files. The interface is very simple and easy to understand. HOW TO USE MP3 GAIN:Īfter installing, open the program. Because the program adjusts the mp3 files directly, without any decoding or re-encoding, so the quality of your MP3 files is not affected. The changes this tool does to your MP3 files are lossless. This is one of the best MP3 file normalizer, a totally Freeware. But instead, the tool does a statistical analysis of the file to determine how loud the file actually sounds to the human ear. The best thing about this tool is, its quite fast, and it doesn’t just do peak normalization as most normalizer software does. While Album Mode corrects the entire album by relating them to the other songs on the album. Track mode corrects the mix of unrelated songs to the level you select. You can use it in two ways, which are Track or Album Mode. It will then adjust the files so they have about the same loudness, without affecting the quality of the recording. MP3Gain is a free utility that analyzes mp3 files and determines how they will sound to the human ear.
