Download Free Android Software - MP3Gain
Application software download free Android: Boosts the volume of your MP3 files without quality loss. MP3Gain analyzes and adjusts MP3 files so that all songs on a CD play at the same volume (with some exceptions). The changes are completely lossless because it doesn't decode and re-encode the file.
MP3Gain also does some other stuff such as peak normalization, dynamic range optimization, and adjusting the overall level of the file to a target volume. All of this is done in a very high-quality manner using advanced algorithms, so that it does not introduce any digital generation loss. This means that if you ever want to return your collection to the original state, you can.
The changes that MP3Gain makes are completely undo-able because it writes the information needed to reverse them as a tag in the MP3 file. This tag is in the APEv2 or ID3v2 format and can be easily accessed and read using any software that supports these formats.
The GUI version of MP3Gain can be used to change the gain for an entire album or a selection of tracks. This can save a lot of time if you have a large collection. This version has been optimized for speed and now uses multi-threaded processing. It is also possible to use a command line version of MP3Gain with AACGain for more control over the processing. Len Trigg has contributed a patch to enable this.
