This package provides shared libraries to interface Pascal program with standard astronomy libraries:

• libpasgetdss.so: Interface with GetDSS to work with DSS images.

• libpasplan404.so: Interface with Plan404 to compute planets position.

• libpaswcs.so: Interface with libwcs to work with FITS WCS.

• libpasspice.so: To work with NAIF/SPICE kernel.

Portable library and tools for manipulating extended attributes.

The LV2 Toolkit (LVTK) contains libraries that wrap the LV2 C API and extensions into easy to use C++ classes. It is the successor of lv2-c++-tools.

IR is a low-latency, real-time, high performance signal convolver especially for creating reverb effects. It supports impulse responses with 1, 2 or 4 channels, in any soundfile format supported by libsndfile.

SoX (Sound eXchange) is a command line utility that can convert various formats of computer audio files to other formats. It can also apply various effects to these sound files, and, as an added bonus, SoX can play and record audio files.

LV2 port of CAPS, a collection of audio plugins comprising basic virtual guitar amplification and a small range of classic effects, signal processors and generators of mostly elementary and occasionally exotic nature.

Patchage is a modular patch bay for audio and MIDI systems based on JACK and ALSA.

Libltc is a POSIX-C Library for handling Linear/Longitudinal Time Code (LTC) data.

Copies a stream, skipping everything except MP3 frames with valid headers. This can be used to copy and concatenate streams, even if they contain extra garbage.

The SoX Resampler library (libsoxr) performs one-dimensional sample-rate conversion. It may be used, for example, to resample PCM-encoded audio.

ZToolkit (Ztk) is a cross-platform GUI toolkit heavily inspired by GTK. It handles events and low level drawing on behalf of the user and provides a high-level API for managing the UI and custom widgets. ZToolkit is written in C and was created to be used for building audio plugin UIs, where the dependencies often need to be kept to a minimum.

The LV2 Toolkit (LVTK) contains libraries that wrap the LV2 C API and extensions into easy to use C++ classes. It is the successor of lv2-c++-tools.

Fluid-3 is Frank Wen's pro-quality GM soundfont.

Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package.

Rakarrack is a richly featured multi-effects processor emulating a guitar effects pedalboard. Effects include compressor, expander, noise gate, equalizers, exciter, flangers, chorus, various delay and reverb effects, distortion modules and many more. Most of the effects engine is built from modules found in the excellent software synthesizer ZynAddSubFX. Presets and user interface are optimized for guitar, but Rakarrack processes signals in stereo while it does not apply internal band-limiting filtering, and thus is well suited to all musical instruments and vocals.

RtAudio is a set of C++ classes that provides a common API for real-time audio input/output. It was designed with the following objectives:

• object-oriented C++ design

• simple, common API across all supported platforms

• only one source and one header file for easy inclusion in programming projects

• allow simultaneous multi-api support

• support dynamic connection of devices

• provide extensive audio device parameter control

• allow audio device capability probing

• automatic internal conversion for data format, channel number compensation, (de)interleaving, and byte-swapping

This package provides a python API to read and write MIDI files.

This package provides a LADSPA plugin for a Wah effect with envelope follower.

libsoundio is a C library providing audio input and output. The API is suitable for real-time software such as digital audio workstations as well as consumer software such as music players.

JACK is a low-latency audio server. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation.

DarkIce is a live audio streamer. It takes audio input from a sound card, encodes it into Ogg Vorbis and/or mp3, and sends the audio stream to one or more IceCast and/or ShoutCast servers.

librosa is a python package for music and audio analysis. It provides the building blocks necessary to create music information retrieval systems.

redumper is a low-level byte perfect CD disc dumper. It supports incremental dumps, advanced SCSI/C2 repair, intelligent audio CD offset detection, among other features. redumper is also a general purpose DVD/HD-DVD/Blu-ray disc dumper.

FAudio is an XAudio reimplementation that focuses solely on developing fully accurate DirectX Audio runtime libraries.
