![]() That is why it is no longer viable to use it as a normalization method. Today the different devices that play music read and follow the Replay Gain? Nope. Of course, we are giving a very simplified explanation, so that it is easily understood. This is saved in a tag in the file and so, when it is run, the music player program knows what amplification it should automatically give to make them sound at very similar levels. Mp3Gain, based on Replay GainĪll this set of theories and measurements are called “human perception” and then a file is measured in what perception it produces and it is calculated what modification a second or third file needs to sound with a similar perception. How did he achieve it? For example, based on the masking effect that says that two sounds that are close in time, if they have similar frequencies, it will happen that the first one masks the second, that is to say, this second one is redundant and is not heard by the human ear. Later an algorithm emerged that calculated the perceptionĪnd not the spikes. Mp4Gain, in addition to normalizing audio and video files, is a functional option today as we will see later. That is, all the songs had the peaks at the maximum possible level without distortion. Then I used that “factor” of possible amplification and amplified the entire recording / song to increase the peaks. It is also easy to use and therefore, it proves to be reliable and efficient.Decades ago there was the so-called peak normalization, which in a simple way, measured the volume peaks of a recording and calculated how much they could be amplified before reaching distortion. Portable MP3Gain does not use many resources when running and we did not register any crashes or bugs while testing it. The interface supports multiple languages, including English, Bulgarian, Japanese, Russian, Spanish and the list goes on. Track, album or constant gain can be applied, as well as undo all the previously made changes.ĭouble clicking on an MP3 file enables you to listen to it, in order to see if the new volume level is suitable. You can input the preferred volume level and apply it by clicking on the “Track Gain” button. The application enables you to find out the exact volume level of each and every MP3 file you have uploaded. ![]() ![]() These are going to be added into a list in the main screen that can be sorted according to path, volume, clipping or track gain. ![]() In the main window you can add an unlimited number of files or entire folders that contain music. The interface is simple and intuitive, meaning that it can be easily used by any type of person, even though they happen to be beginners. Most importantly, the Windows registry and Start menu/screen are not going to get updated with new entries. Since this software utility does not require installation, it means that you can easily copy the files to the hard drive or even to a portable storage unit, such as a USB drive, so that you can run it directly on any computer you have access to. Portable MP3Gain is the portable version of MP3Gain, and it can help you control the volume level of your MP3 files.
