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.
