Sophisticated audio processor for automatic loudness adjustment and audio files splitting. LASTAR allows loudness adjustement and file splitting of a batch of audio recordings with just few clicks. 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. Other features include automatic file analysis to set up the best parameters, automated amplifier gain adjustment, noise estimation for file splitting, RMS Amplifier with fast lookahead limiter to prevent clipping, a 3 bands semi-parametric equalizer, smooth automatic Gain Control (AGC), preset management, noise gate and more.

LASTAR changelog:
Installer improved (thanks to Roberto).
