The Sound Normalizer reduce, improves, regains a volume and file size without losing ID3, FLAC, Ogg tags of Mp3, FLAC, Ogg, APE 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, FLAC, Ogg, APE and Wav files. It contains batch processor and it allows to fulfill the batch test, batch normalization and batch converting of Mp3, FLAC, Ogg, APE and Wav files. The volume level is represented graphically in percentage or decibels (dB). The Wav, Ogg, APE 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 the volume of a scanned file directly without usage tags. The Sound Normalizer also allows editing ID3, FLAC, Ogg Tags, converting Wav to Mp3, Mp3 to Mp3 (with saving ID3 tags), Mp3 to Wav, Wav to FLAC, FLAC to Wav, Wav to APE, APE to Wav, APE to Mp3, FLAC to Mp3 (with saving ID3, FLAC tags), Wav to Ogg, Ogg to Wav files using Lame MP3 Encoder 3.99.2, FLAC Encoder 1.2.1, Monkey's Audio Encoder 4.11, Ogg Vorbis Encoder 1.3.2 (aoTuV 6.03), listening Mp3, FLAC, Ogg, APE and Wav files using the build-in audio player. Here are some key features of "Sound Normalizer": Batch processor for Mp3 FLAC, Ogg, APE and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2) files; Batch normalizing for Mp3 FLAC, Ogg, APE and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2) files; Batch converting for Mp3 FLAC, Ogg, APE and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2) files; Batch test for Mp3 FLAC, Ogg, APE and Wav (PCM 8, 16, 24, 32 bits, DSP, GSM, IMA ADPCM, MS ADPCM, AC3, MP3, MP2) files.
