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.
