What is the use of playback gain in the player? What is the difference between an album and a track?
Generally speaking, replaygain refers to a method by which software automatically adjusts the volume to the correct volume for each song and album during playback.
Because the volume of each recording is different, even if your playback device maintains the same volume, some songs may be too loud and others too quiet, and playback gain can solve such situations.
Specifically, playback gain is a label that can be stored in an audio file, indicating a certain gain value (+3.1 dB, -2.0 dB, etc.). Players that support playback gain can read these tags and play Adjust the internal volume from time to time to keep the actual volume of different songs at the same level without changing the system volume. At the same time, playback gain is also a standard, which specifies a set of algorithms to automatically detect the volume of audio files, so as to realize the purpose of automatically adjusting the volume difference between different songs by the software. . The newest current standard is Playback Gain 2.0, which is more accurate than previous versions.
The playback gain tab is divided into two categories, one is album gain and the other is track gain. Album gain is for treating an album as a whole and bringing different albums to the same volume; track gain is used to balance the volume differences of different songs within the same album. The reason for the distinction between the two is that although there are differences in volume within the same album, they are often intentional on the part of the recorder. By distinguishing between two types of gain tags, users can choose to apply playback gain at the album or individual level.
Mp4Gain does not use Replay Gain as its main normalization method, since it has already developed its own much more advanced methods. However, if you wish, you have the option of selecting Replay Gain to be used as a method in Mp4Gain.
But for the common user, this is not necessary, since Mp4Gain has, as we said, more modern, efficient and sophisticated methods.
