LASTAR is a batch (non-interactive) audio processor for loudness adjustment and file splitting of a batch of audio recordings, using audio transparent maximizer.

At the opposite of usual available softwares, loudness normalization is done on signal power, which leads to a louder and more homogeneous result than a usual "peak" normalization, in particular on live recordings.

Its purposes are :

-to split, equalize and normalize digitized analog tapes or vinyls,
-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.
