Let me introduce you to the program MP3Gain Full 1.2 beta. Certainly, many faced with the problem when the volume in mp3 file varies greatly. For example, in a folder with thousands of songs, volume changes very, very much. "Happy owners of" active speakers, cost 10 dollars of that will likely not be affected. But those who use high-quality acoustics, and especially those who have musical education, probably feel uncomfortable. Yet not long ago, I leveled the volume in different music editors, but it is a very laborious and thankless job. After adjustment for even a few dozen songs she left a lot of time and effort. But recently introduced utility MP3Gain Full easily be coped with this task in a few minutes. The Programme should only indicate "normal" volume and directory with MP3 files, and it does everything for you.
