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++.

Lplex ~ Create Lossless Audio DVDs


Lplex is a console application meant to provide a free, quick, and hopefully painless way to:

  • Create lossless “audio-only” dvd-video discs from wav or flac audio files, featuring:
    1. gapless playback.
    2. md5 verification of audio data.
    3. archival (dvd-rom) content.
  • Losslessly extract unencrypted lpcm audio streams from dvd-video to wav or flac format.

You’re already fully equipped for hi-res audio (up to 24-bit/96khz) if you have a typical dvd-player and digital amp, and lplex is a way to take advantage of this.

FluidSynth ~ A SoundFont Synthesizer


FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution. FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps.

Features:

  • Cross platform support (Linux, macOS and Windows to name a few)
  • SoundFont 2 support
  • SoundFont 3 support (vorbis-compressed SF2)
  • Realtime effect control using SoundFont 2.01 modulators
  • Playback of MIDI files
  • Shared library which can be used in other programs
  • Built in command line shell

FluidPatcher ~ GUI & Automation

FluidPatcher is a performance-oriented interface for FluidSynth built using wxpython to create a simple GUI that allows live editing, selecting, and playing of patches. A patch is a collection of settings such as soundfont presets for each MIDI channel, control-change/sysex messages to send when the patch is selected, and midi router or effects settings. Groups of patches are stored in banks, which are saved as human-readable and -editable YAML files. This allows a musician to easily create complex combinations of synthesizer settings ahead of time and switch between them on the fly during a performance.

Features:

  • Live playing: Play on your MIDI controller and hear the results
  • Customization: Create your own combinations of instruments/effects
  • Extendability: Use the included libraries to design your own implementations/software

Mp3Wrap ~ Create mp3 Albums


Mp3Wrap is a free and independent alternative to AlbumWrap. It’s a command-line utility that quickly wraps two or more mp3 files into one single large playable mp3, without losing filenames and ID3 information (and without decoding or encoding). It’s also possible to include other non mp3 files, such as playlists, info files and cover images inside the new mp3. You can easily produce a large mp3 file that you can split at any time by using mp3splt and in few seconds you’ll have all the original files again! It’s useful because files created with Mp3Wrap are much easier to share.
