shntool ~ WAVE Processing & Reporting Utility


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 ~ Multiprocess Audio Converter


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.

Features:

  • Supported input formats / codecs: WAV, AIFF, CAF, FLAC, WavPack, Monkey’s Audio, ALAC.
  • 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).

cdparanoia ~ Linux Digital Audio Extraction


Cdparanoia is a Compact Disc Digital Audio (CDDA) Digital Audio Extraction (DAE) tool, commonly known on the net as a ‘ripper’. The application is built on top of the Paranoia library, which is doing the real work (the Paranoia source is included in the cdparanoia source distribution). Cdparanoia reads audio from the CDROM directly as data, with no analog step between, and writes the data to a file or pipe in WAV, AIFC or raw 16 bit linear PCM.

Cdparanoia is a bit different than most other CDDA extration tools. It contains few-to-no ‘extra’ features, concentrating only on the ripping process and knowing as much as possible about the hardware performing it. Cdparanoia will read correct, rock-solid audio data from inexpensive drives prone to misalignment, frame jitter and loss of streaming during atomic reads. Cdparanoia will also read and repair data from CDs that have been damaged in some way.

Cdparanoia is easy to use and administrate; It has no compile time configuration, happily autodetecting the CDROM, its type, its interface and other aspects of the ripping process at runtime. A single binary can serve the diverse hardware of the do-it-yourself computer laboratory from Hell.

CLAMPS ~ Common Lisp Aided Music Production System


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.

Bitter ~ Bitscope & Intersample Clip Monitor


Bitter shows how many of the available bits are being used by the audio signal, reports clipping samples, and estimates when digital-to-analog conversion would cause inter-sample clips. Typical uses for a bitscope include: verifying that a render dither is working properly; verifying that a particular plugin is not reducing the signal bit depth; testing for faulty audio source data.

Features:

  • Check for Intersample Clipping that may appear during digital-to-analog conversion
  • Detailed display of the usage density of each bit
  • Reveal the bitrate of the digital signal, which may well differ from that of the file’s bitrate or your DAW’s audio engine bitrate
  • Display the audio sample rate

DSOAL ~ DirectSound DLL Replacement


This project is for a DirectSound DLL replacement. It implements the DirectSound interfaces by translating the calls to OpenAL, and fools applications into thinking there is a hardware accelerated sound device. EAX is also implemented (up to version 4) by using OpenAL’s EAX extension, allowing for environmental reverb with sound obstruction and occlusion effects.

Effectively, this allows DirectSound applications to enable their DirectSound3D acceleration path, and turn on EAX. The actual processing is being done by OpenAL with no hardware acceleration requirement, allowing it to work on systems where audio acceleration is not otherwise available.

Or more succinctly: it enables DirectSound3D surround sound and EAX for systems without the requisite hardware.

OpenMusic ~ Music Composition Language


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”.
