![]() ![]() If, however, the volume of the input audio varies significantly over time – as is the case with many "real world" recordings – the standard normalization algorithm will not give satisfying result. This works fine, as long as the volume of the input audio is constant, more or less. So if S_max denotes the highest magnitude sample in the whole input audio and Peak is the desired peak magnitude, then the gain factor will be chosen as G=Peak/abs(S_max). Consequently, the gain factor must be chosen in a way that won't cause clipping (distortion), even for the input sample that has the highest magnitude. How It WorksĪ "standard" (non-dynamic) audio normalization algorithm applies the same constant amount of gain to all samples in the file. The "native" API is written in C++, but language bindings for C99, Microsoft.NET, Java, Python and Pascal are provided. Last but not least, the "core" library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). Furthermore, it can be integrated into your favourite DAW (digital audio workstation), as a VST plug-in, or into your favourite media player, as a Winamp plug-in. The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. It will retain 100% of the dynamic range within each "local" region of the audio file. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying "dynamic range compressing". ![]() In other words: The Dynamic Audio Normalizer will "even out" the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. This allows for applying extra gain to the "quiet" sections of the audio while avoiding distortions or clipping the "loud" sections. However, in contrast to more "simple" normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. This software is provided 100% free of charge ĭynamic Audio Normalizer is a library for advanced audio normalization purposes.Here are some key features of 'Sound Normalizer':īatch processor for Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC, Wav files īatch normalizing for Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC, Wav files īatch converting for Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC, Wav files īatch test for Mp3, Mp4, FLAC, Ogg, APE, AAC, ALAC, Wav files. 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. The Mp3 Normalizer allows to modify a volume of a scanned file directly without usage Encoder and Tags. The Mp3 normalization and test is fulfilled on an average level (RMS normalization). ![]() ![]() 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). 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. It is reached by the test and normalization of the volume level of Mp3, Mp4, Wav, FLAC, Ogg, APE, AAC, ALAC files. The Sound Normalizer increases, reduce, improves, 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. ![]()
