Sound Normalizer increases, reduces, improves, and regains a volume and file size without losing ID3, Mp4, FLAC, Ogg tags of Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2, OGG, A-LAW, u-LAW) files. It is reached by the test and normalization of the volume level of Mp3, Mp4, Wav, FLAC, Ogg, APE, AAC, ALAC files.

It contains batch processor, which allows to fulfill the batch test, batch normalization and batch converting of Mp3, Mp4, Wav, FLAC, Ogg, APE, AAC, ALAC files. The Mp4, Wav, Ogg, APE, AAC, ALAC and FLAC normalization and test is fulfilled on a peak level (Peak Normalization) and on an average level (RMS normalization). The Mp3 normalization and test is fulfilled on an average level (RMS normalization). The Mp3 Normalizer allows to modify a volume of a scanned file directly without usage Encoder and Tags.

The Sound Normalizer also allows editing ID3, Mp4, FLAC, Ogg Tags, converting Mp3, Mp4, Wav, FLAC, Ogg, APE, AAC, ALAC files using Lame MP3 Encoder 3.99.2, FLAC Encoder 1.2.1, Monkey's Audio Encoder 5.5, Ogg Vorbis Encoder 1.3.7, FAAC Encoder 1.30, listening Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC, Wav files using the build-in audio player.
