shntool is a multi-purpose WAVE data processing and reporting utility. File formats are abstracted from its core, so it can process any file that contains WAVE data, compressed or not – provided there exists a format module to handle that particular file type.
shntool has native support for .wav files. If you want it to work with other lossless audio formats, you must have the appropriate helper program installed. The “Helper programs” section below contains links to helper programs for each format that shntool supports.
caudec is a command-line utility that transcodes (converts) audio files from one format (codec) to another, among other things.
It leverages multi-core CPUs and runs multiple processes concurrently (one per file and per codec, and more than one thread per codec when it supports it). The objective is to hog the CPU as much and as long as possible. One strategy is to sort input files by size, so that the largest files potentially get more threads towards the end of the job.
Supported output formats / codecs: all of the above, as well as LossyWAV / LossyFLAC, MP3, AAC (.m4a), Ogg Vorbis, Opus.
Supported platforms: macOS, Linux.
Transcoding to several different codecs at once is possible. In that case, decoding of input files is done only once.
Metadata is preserved (as much as possible) from one codec to another.
Artwork can be embedded into each file, and / or copied to the output directory. It can be done selectively (e.g. embed and / or copy one image for lossless files, and another image for lossy files).
Audio can be resampled (e.g. 48kHz to 44.1kHz) and downmixed (e.g. 6 channels to stereo). A profile can be provided to set a maximum value for the number of channels, bit depth and sampling rate. When a profile is provided, the source will only be altered after decoding and before encoding, if some metric of the source is above the given profile.
Multiprocess ReplayGain scanner for FLAC, WavPack, MP3, Ogg Vorbis, Opus.
Ability to hard link lossy files to a different directory when encoding to WavPack Hybrid. The point is to have two libraries that takes the storage of just one, with a lossy collection that has its own root directory and that’s easy to drag and drop to a device such as a smartphone or a Digital Audio Player (DAP).
Ability to touch files and album directories using metadata to reflect the music’s release date and duration (see example below).

Foobar2000 displays artwork in a panel which can be added and configured to suit your preferences. The artwork panel displays the image file associated with an audio track. If the standard options are insufficient, Foobar’s image handling can be extended via additional components.
To add an artwork panel to the default user interface (DUI), Enable Layout Editing Mode from the menu View > Layout. Add the Album Art Viewer from the Selection Information section.
Selecting the Album Art Viewer on the Add New UI Element menu
Clamps, short for “Common Lisp Aided Music Production System”, is a software system for realtime and non-realtime music production written in Common Lisp. It enables a seamless workflow between high-level structures to define musical processes all the way down to low level DSP definitions for sound creation including browser based interfaces for interactive work and control useable for live performances. In that respect it combines features of systems like OpenMusic, SuperCollider or the Pure Data/Max family of software.
Rusty Pipes is a digital organ instrument compatible with GrandOrgue sample sets. It features both graphical and text-based user interface, can be controlled via MIDI and play back MIDI files. Rusty Pipes can stream samples from disk instead of load them into RAM, though a RAM precache mode similar to GrandOrgue and Hauptwerk is available too.
OpenMusic (OM) is a visual programming language based on Common Lisp. Visual programs are created by assembling and connecting icons representing functions and data structures. Most programming and operations are performed by dragging an icon from a particular place and dropping it to an other place. Built-in visual control structures (e.g. loops) are provided, that interface with Lisp ones. Existing CommonLisp/CLOS code can easily be used in OM, and new code can be developed in a visual way.
OM may be used as a general purpose functional/object/visual programming language. At a more specialized level, a set of provided classes and libraries make it a very convenient environment for music composition. Above the OpenMusic kernel, live the OpenMusic Projects. A project is a specialized set of classes and methods written in Lisp, accessible and visualisable in the OM environment. Various classes implementing musical data / behaviour are provided. They are associated with graphical editors and may be extended by the user to meet specific needs. Different representations of a musical process are handled, among which common notation, midi piano-roll, sound signal. High level in-time organisation of the music material is proposed through the concept of “maquette”.
OM-SoX is a library for multichannel audio manipulation and functional batch processing for OpenMusic, a visual programming environment based on CommonLisp / CLOS.
Partiels is an audio analysis application that allows you to explore the content and characteristics of sounds.
Features:
Partiels allows analysis of one or several audio files using Vamp plug-insloading data files, visualizing, editing, organizing, and exporting the results as images or text files that can be used in other applications such as Max, Pure Data, Open Music, etc.
Windows, Mac & Linux support
Multiformat support
Multichannel support
Multiaudiofile support
Analyzing audio with Vamp plug-ins
Visualizing results as spectrogram, lines, and markers
Loading results from CSV, LAB, JSON, CUE & SDIF formats
Batch processing
Command line interface to analyze, export, and convert results
Consolidating documents for sharing
Alongside Partiels, a wide range of analyses based on audio engines developed at IRCAM and outside are ported to Vamp plug-ins. These plug-ins allow you to perform FFT, LPC, transient, fundamental, formant, tempo, TTS and many other analyses. You can also find a large number of analysis plug-ins on the Vamp plug-ins website.
