MissFITS is a program that performs basic maintenance and packaging tasks on FITS files:

• add/edit FITS header keywords

• split/join MEF files

• unpack/pack FITS data-cubes

• create/check/update FITS checksums, using R. Seaman's protocol

This package provides a collection of Space Telescope Science Institute utility functions.

Gpredict is a real-time satellite tracking and orbit prediction application. It can track a large number of satellites and display their position and other data in lists, tables, maps, and polar plots (radar view). Gpredict can also predict the time of future passes for a satellite, and provide you with detailed information about each pass.

Some core features of Gpredict include:

• Tracking of a large number of satellites only limited by the physical memory and processing power of the computer

• Display the tracking data in lists, maps, polar plots and any combination of these

• Have many modules open at the same either in a notebook or in their own windows. The modules can also run in full-screen mode

• You can use many ground stations

• Predict upcoming passes

• Gpredict can run in real-time, simulated real-time (fast forward and backward), and manual time control

• Detailed information both the real time and non-real time modes

• Doppler tuning of radios via Hamlib rigctld

• Antenna rotator control via Hamlib rotctld

SOXS is a software suite which can create simulated X-ray observations of astrophysical sources with almost any existing or planned X-ray observatory. The goal of SOXS is to provide a comprehensive set of tools to design source models and convolve them with simulated models of X-ray instruments. This package was originally developed to support the Lynx X-ray Observatory mission concept, but has evolved to support other missions as well.

The COde-independent Organized LEns STandard (COOLEST) defines a set of conventions to be shared across the strong lensing community, in order to consistently store, share and improve lens modeling analyses. In short, this project provides tools to manipulate lens models as a single, human-readable JSON template file alongside Python routines for visualizing and comparing lens models possibly obtained from different modeling codes.

Stackistry implements the lucky imaging principle of astronomical imaging: creating a high-quality still image out of a series of many (possibly thousands) low quality ones (blurred, deformed, noisy). The resulting image stack typically requires post-processing, including sharpening (e.g. via deconvolution). Such post-processing is not performed by Stackistry.

CCfits is an object oriented interface to the cfitsio library. It is designed to make the capabilities of cfitsio available to programmers working in C++. It is written in ANSI C++ and implemented using the C++ Standard Library with namespaces, exception handling, and member template functions.

The iers package provides access to the tables provided by the International Earth Rotation and Reference Systems service, in particular the Earth Orientation data allowing interpolation of published UT1-UTC and polar motion values for given times. The UT1-UTC values are used in Time and Dates (astropy.time) to provide UT1 values, and the polar motions are used in astropy.coordinates to determine Earth orientation for celestial-to-terrestrial coordinate transformations.

Portable library and tools for manipulating extended attributes.

Dcadec is a DTS Coherent Acoustics surround sound decoder with support for HD extensions.

BS1770GAIN is a loudness scanner compliant with ITU-R BS.1770 and its flavors EBU R128, ATSC A/85, and ReplayGain 2.0. It helps normalizing the loudness of audio and video files to the same level.

FreePats is a project to create a free and open set of GUS compatible patches that can be used with softsynths such as Timidity and WildMidi.

RSound allows you to send audio from an application and transfer it directly to a different computer on your LAN network. It is an audio daemon with a much different focus than most other audio daemons.

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

CLAP stands for CLever Audio Plugin. It is an audio plugin ABI which defines a standard for Digital Audio Workstations and audio plugins to work together.

DRC is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation. DRC generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction. DRC doesn't provide convolution features, and provides only some simplified, although really accurate, measuring tools.

LibOpenMPT is a cross-platform C++ and C module playback library. It is based on the player code of the Open ModPlug Tracker project.

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.

This project is a rebirth of a direct integration between Bluez and ALSA. Since Bluez >= 5, the built-in integration has been removed in favor of 3rd party audio applications. From now on, Bluez acts as a middleware between an audio application, which implements Bluetooth audio profile, and a Bluetooth audio device. BlueALSA registers all known Bluetooth audio profiles in Bluez, so in theory every Bluetooth device (with audio capabilities) can be connected. In order to access the audio stream, one has to connect to the ALSA PCM device called bluealsa. The device is based on the ALSA software PCM plugin.

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

Autotalent is a LADSPA plugin for real-time pitch-correction. Among its controls are allowable notes, strength of correction, LFO for vibrato and formant warp.

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.

Noise Repellent is an LV2 plugin to reduce noise. It has the following features:

1. Spectral gating and spectral subtraction suppression rule

2. Adaptive and manual noise thresholds estimation

3. Adjustable noise floor

4. Adjustable offset of thresholds to perform over-subtraction

5. Time smoothing and a masking estimation to reduce artifacts

6. Basic onset detector to avoid transients suppression

7. Whitening of the noise floor to mask artifacts and to recover higher frequencies

8. Option to listen to the residual signal

9. Soft bypass

10. Noise profile saved with the session

Libzita-resampler is a C++ library for resampling audio signals. It is designed to be used within a real-time processing context, to be fast, and to provide high-quality sample rate conversion.
