Dynamic Audio Normalizer is a library for advanced audio normalization purposes. 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 re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. 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. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compression”. It will retain 100% of the dynamic range within each “local” region of the audio file.
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. 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. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). The “native” API is written in C++, but language bindings for C99 Microsoft.NET, Java, Python and Pascal are provided.
LASTAR is a batch (non-interactive) audio processor for loudness adjustment and file splitting of a batch of audio recordings, using an audio transparent maximizer.
At the opposite of usual available software, loudness normalization is done on signal power, which leads to a louder and more homogeneous result than the usual “peak” normalization, in particular on live recordings.
Its purpose is:
- to split, equalize and normalize digitized analog tapes or vinyl
- to split, equalize and normalize live recordings from microphones (ex ZOOM H2 recordings)
- fast and homogeneous normalization of a group of files (compilation for instance)
- loudness and dynamic reduction for listening in a noisy environment (car…)
- and so on…
This software aims to be very fast and easy to use : the most efficient computing techniques have been implemented, and there are very few parameters to set (most of them are automatically adjusted by analyzing the file).
It embeds :
- an automatic RMS normalizer,
- an Automatic Gain Controller (compressor)
- a 10 bands automatic equalizer
- a 3 bands semi-parametric equalizer
- a file splitter
- a noise gate
- preset management
- a preview function.
WaveShop is a free, open-source audio editor for Windows XP/Vista/7/8 32-bit and 64-bit. WaveShop is fast, lightweight, and bit-perfect, meaning samples aren’t altered unless they need to be. Editing a portion of an audio file only affects that portion; the rest of the file is untouched. Blocks of audio can be cut and pasted without changing their contents at all. This is especially useful for patching a finished master without corrupting its dither. Waveshop’s features include peak, RMS and spectral analysis, normalizing, fading, sample rate conversion, audio generation, plug-ins, and more, all with unlimited undo and comprehensive help.
loudgain is a versatile ReplayGain 2.0 loudness normalizer, based on the EBU R128 / ITU BS.1770 standard (-18 LUFS) and supports FLAC / Ogg / MP2 / MP3 / MP4 / M4A / ALAC & Opus audio files. It uses the well-known mp3gain command line syntax but will never modify the actual audio data.
Just what you ever wanted: the best of mp3gain, ReplayGain 2.0 and Linux combined. Spread the word!
TAudioConverter is a audio converter and extractor. It can convert almost any audio format to aac, ac3, mp3, flac, wav, ogg, opus or mpc. SoX is used to apply effects such as normalization, volume change etc. It can also extract audio streams from video files and encode them. Video files with more than one audio stream is supported. It is possible to run up to 8 simultaneous processes to shorten encoding time.
VLevel keeps your music from making you jump out of your seat, and it keeps you from having to fiddle with the volume constantly. It’s different from other dynamic compressors because it looks ahead. You can think of VLevel as someone who knows your music by heart, and turns the volume up during quiet passages, but smoothly turns it back down when he knows a loud part is coming. It’s great for making CDs to listen to in your car, or to play background music on your computer.
