Dynamic Audio Normalizer is a library and a command-line tool for audio normalization. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more "simple" normalization algorithms, the Dynamic Audio Normalizer dynamically adjusts the gain factor to the input audio. This allows for applying extra gain to the "quiet" parts of the audio while avoiding distortions or clipping the "loud" parts. In other words, the volume of the "quiet" and the "loud" parts will be harmonized.

Command-Line Usage
Dynamic Audio Normalizer program can be invoked via command-line interface (CLI), either manually from the command prompt or automatically by a batch file.
Basic CLI syntax:
The basic Dynamic Audio Normalizer command-line syntax is as follows:
DynamicAudioNormalizerCLI.exe -i -o [options]
Note that the input file and the output file always have to be specified, while all other parameters are optional. But take care, an existing output file will be overwritten!
Also note that the Dynamic Audio Normalizer program uses libsndfile for input/output, so a wide range of file formats (WAV, W64, FLAC, Ogg/Vorbis, AIFF, AU/SND, etc) as well as various sample types (ranging from 8-Bit Integer to 64-Bit floating point) are supported.
Passing "raw" PCM data via pipe is supported too. Just specify the file name "-" in order to read from or write to the stdin or stdout stream, respectively. When reading from the stdin, you have to explicitly specify the input sample format, channel count and sampling rate.
For a list of all available options, please run DynamicAudioNormalizerCLI.exe --help from the command prompt. Also see to the configuration chapter for more details!
Usage examples:
Read input from Wave file and write output to a Wave file again:
DynamicAudioNormalizerCLI.exe -i "in_original.wav" -o "out_normalized.wav"
Read input from stdin (input is provided by FFmpeg via pipe) and write output to Wave file:
ffmpeg.exe -i "movie.mkv" -loglevel quiet -vn -f s16le -c:a pcm_s16le - | DynamicAudioNormalizerCLI.exe -i - --input-bits 16 --input-chan 2 --input-rate 48000 -o "output.wav"
Read input from Wave file and write output to stdout (output is passed to FFmpeg via pipe):
DynamicAudioNormalizerCLI.exe -i "input.wav" -o - | ffmpeg.exe -loglevel quiet -f s16le -ar 44100 -ac 2 -i - -c:a libmp3lame -qscale:a 2 "output.mp3"
SoX integration:
As an alternative to the Dynamic Audio Normalizer command-line front-end, the Dynamic Audio Normalizer library may also be used as an effect in Sound eXchange (SoX), a versatile audio editor and converter.
Note, however, that standard SoX distributions do not currently support the Dynamic Audio Normalizer. Instead, a special patched build of SoX that has the Dynamic Audio Normalizer effect enabled is required!
When working with SoX, the Dynamic Audio Normalizer can be invoked by adding the "dynaudnorm" effect to your effect chain, which can be done as follows:
DynamicAudioNormalizerSoX.exe -S "in_original.wav" -o "out_normalized.wav" dynaudnorm [options]
For details about the SoX command-line syntax, please refer to the SoX documentation, or type DynamicAudioNormalizerSoX.exe --help-effect dynaudnorm for a list of available options.
