What’s more, you are offered details about each audio item, such as filename, status, volume, bitrate, frequency, and destination and source locations. The program is able to automatically normalize the volume of MP3 files or lets you adjust the volume according to your preferences. Mp3Gain PRO offers support for batch processing, which means you can insert multiple MP3 files and process them at the same time. Plus, you can add the content of an entire folder to the list. It boasts a clean and intuitive layout that allows you to upload files into the working environment using the built-in browse function or “drag and drop” operations.
The Replay Gain proposal sets out a simple way of calculating and representing the ideal replay gain for every track and album.Mp3Gain PRO is a lightweight Windows application whose purpose is to help users normalize the volume of MP3 files. However, there is no consistent standard by which to define the appropriate replay gain which mp3 encoders and players agree on, and no automatic way to set the volume adjustment for each track – until now. The later ID3v2 standard also incorporates the ability to store a track relative volume adjustment, which can be used to "fix" quiet or loud sounding mp3s. It's already possible to store the title, artist, and CD track number within an mp3 file using the ID3 standard. This concept is called "MetaData" – data about data. There is a remarkably simple solution to this annoyance, and that is to store the required replay gain for each track within the track. If we add to this chaos the inconsistent quality of mp3 encoding, it's no wonder that a random play through your music collection can have you leaping for the volume control every other track. Whilst different musical moods require that some tracks should sound louder than others, the loudness of a given CD has more to do with the year of issue or the whim of the producer than the intended emotional effect.
The perceived loudness of mp3s is even more variable.
This is a completely optional feature and can easily be turned off should it interfere with your mp3 playback.
It also supports storing analysis information transparently within the mp3 file itself, so you only ever need analyse each file once.
The other bonus of using MP3Gain over other similar software is that it is completely lossless, because it adjusts the mp3 file directly rather than de-coding and re-encoding it. MP3Gain works slightly differently to other programs with similar functions because it does not simply do peak normalisation but instead uses statistical analysis to analyse how loud a song sounds to human ears. No longer will you have to reach for your volume control every time a particularly loud or quiet song comes on! Your entire mp3 collection can be played at one consistent volume without adjustment.
MP3Gain is a free volume balancing tool, used to adjust your collection of mp3s so that they all play at the same volume.
