LASTAR ~ Batch File Splitting & Normalization

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.

v2strip ~ Remove mp3 ID3v2 Tags

v2strip is a simple command-line utility that lets you remove the ID3v2 tag from an MP3 file. The ID3v2 format is nice in many ways, but it can cause problems when being parsed by MP3 players and utilities that don’t support ID3v2 tags.

Humdrum Toolkit ~ Music Analysis & Research

David Huron created Humdrum in the 1980s, and it has been used steadily for decades. Humdrum is a set of command-line tools that facilitates musical analysis, as well as a generalized syntax for representing sequential streams of data. Because it’s a set of command-line tools, it’s program-language agnostic. Many have employed Humdrum tools in larger scripts that use PERL, Ruby, Python, Bash, LISP, and C++.
