Xmp is a portable module player that plays over 90 mainstream and obscure module formats, including Protracker MOD, Fasttracker II XM, Scream Tracker 3 S3M and Impulse Tracker IT files.

LibOFA is an audio fingerprint library, created and provided by MusicIP.

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions.

This package provides a simple sound library for C++.

This package provides a conversion utility for LV2 Plugin developers to generate C headers from Turtle files.

This C library provides an encoder and a decoder for the GSM 06.10 RPE-LTP lossy speech compression algorithm.

This package provides a command-line AAC-encoder.

Pure Python bindings for Augeas.

Augeas is a library and command line tool for programmatically editing configuration files in a controlled manner. Augeas exposes a tree of all configuration settings and a simple local API for manipulating the tree. Augeas then modifies underlying configuration files according to the changes that have been made to the tree; it does as little modeling of configurations as possible, and focuses exclusivley on transforming the tree-oriented syntax of its public API to the myriad syntaxes of individual configuration files.

Pamtester is a tiny utility program to test the pluggable authentication modules (PAM) facility, specifically designed to help PAM module authors to intensively test their own modules.

This package provides a library to generate HOTPs as specified in RFC 4226 and TOTPs as specified in RFC 6238.

The Yubico PAM module provides an easy way to integrate the YubiKey into your existing user authentication infrastructure.

The OATH Toolkit provides various components for building OTP authentication systems:

• oathtool, a command-line tool for generating & validating OTPs.

• liboath, a C library for OATH handling.

• pskctool, a command-line tool for manipulating secret key files in the PSKC format described in RFC6030.

• libpskc, a shared and static C library for PSKC handling.

• pam_oath, a PAM module for pluggable login authentication.

Supported technologies include the event-based HOTP algorithm (RFC4226), the time-based TOTP algorithm (RFC6238), and PSKC (RFC6030) to manage secret key data.

oauth2l (pronounced ``oauth tool'') is a simple command-line tool for working with Google OAuth 2.0 written in Go. Its primary use is to fetch and print OAuth 2.0 access tokens, which can be used with other command-line tools and scripts.

AutoGen is a program to ease the maintenance of programs that contain large amounts of repetitive text. It automates the construction of these sections of the code, simplifying the task of keeping the text in sync. It also includes an add-on package called AutoOpts, which is specialized for the maintenance and documentation of program options.

Autoconf Archive is a collection of over 450 new macros for Autoconf, greatly expanding the domain of its functionality. These macros have been contributed as free software by the community.

The `config.guess' script tries to guess a canonical system triple, and `config.sub' validates and canonicalizes. These are used as part of configuration in nearly all GNU packages (and many others).

Autoconf offers the developer a robust set of M4 macros which expand into shell code to test the features of Unix-like systems and to adapt automatically their software package to these systems. The resulting shell scripts are self-contained and portable, freeing the user from needing to know anything about Autoconf or M4.

GNU pyconfigure provides template files for easily implementing standards-compliant configure scripts and Makefiles for Python-based packages. It is designed to work alongside existing Python setup scripts, making it easy to integrate into existing projects. Powerful and flexible Autoconf macros are available, allowing you to easily make adjustments to the installation procedure based on the capabilities of the target computer.

Automake the part of the GNU build system for producing standards-compliant Makefiles. Build requirements are entered in an intuitive format and then Automake works with Autoconf to produce a robust Makefile, simplifying the entire process for the developer.

Autobuild is a package that processes build logs generated when building software. Autobuild is primarily focused on packages using Autoconf and Automake, but can be used with other build systems too. Autobuild generates an HTML summary file, containing links to each build log. The summary includes project name, version, build hostname, host type (cross compile aware), date of build, and indication of success or failure. The output is indexed in many ways to simplify browsing.
