This package implements functionality for simulating X-ray emission from astrophysical sources.

X-rays probe the high-energy universe, from hot galaxy clusters to compact objects such as neutron stars and black holes and many interesting sources in between. pyXSIM makes it possible to generate synthetic X-ray observations of these sources from a wide variety of models, whether from grid-based simulation codes such as FLASH, Enzo, and Athena, to particle-based codes such as Gadget and AREPO, and even from datasets that have been created 'by hand', such as from NumPy arrays. pyXSIM also provides facilities for manipulating the synthetic observations it produces in various ways, as well as ways to export the simulated X-ray events to other software packages to simulate the end products of specific X-ray observatories.

SunPy is package for solar physics and is meant to be a free alternative to the SolarSoft data analysis environment.

It includes an interface for searching and downloading data from multiple data providers, data containers for image and time series data, commonly used solar coordinate frames and associated transformations, as well as other functionality needed for solar data analysis.

This package implements a functionality of AI-powered automated pipeline for lens modeling, with lenstronomy as the modeling engine.

Features:

• AI-automated forward modeling for large samples of galaxy-scale lenses

• flexible: supports both fully automated and semi-automated (with user tweaks) modes

• multi-band lens modeling made simple

• supports both galaxy–galaxy and galaxy–quasar systems

• effortless syncing between local machines and High-Performance Computing Cluster

This package provides ALFA, which can identify and fit hundreds of lines in emission line spectra in just a few seconds with following features:

• A population of synthetic spectra is generated using a reference line catalogue.

• The goodness of fit for each synthetic spectrum is calculated. The best sets of parameters are retained and the rest discarded.

• A new population of synthetic spectra is obtained by averaging pairs of the best performers.

• A small fraction of the parameters of the lines in the new generation are randomly altered.

• The process repeats until a good fit is obtained.

SNData provides an access to data releases published by a variety of supernova (SN) surveys. It is designed to support the development of scalable analysis pipelines that translate with minimal effort between and across data sets. A summary of accessible data is provided below. Access to additional surveys is added upon request or as needed for individual research projects undertaken by the developers.

This package provides tools for machine learning and data mining in astronomy.

This package provides a Square Kilometre Array (SKA) Science Data Processor (SDP) function library for radio astronomy.

The drizzle library is a Python package for combining dithered images into a single image. This library is derived from code used in DrizzlePac. Like DrizzlePac, most of the code is implemented in the C language. The biggest change from DrizzlePac is that this code passes an array that maps the input to output image into the C code, while the DrizzlePac code computes the mapping by using a Python callback. Switching to using an array allowed the code to be greatly simplified.

Halotools is a specialized python package for building and testing models of the galaxy-halo connection, and analyzing catalogs of dark matter halos. The core feature of Halotools is a modular platform for creating mock universes of galaxies starting from a catalog of dark matter halos obtained from a cosmological simulation.

Portable library and tools for manipulating extended attributes.

Audacity is a multi-track audio editor designed for recording, playing and editing digital audio. It features digital effects and spectrum analysis tools.

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

WildMIDI is a simple software midi player which has a core softsynth library that can be used with other applications.

SoundTouch is an audio processing library for changing the tempo, pitch and playback rates of audio streams or audio files. It is intended for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects.

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

VO-AACENC is the VisualOn implementation of Advanced Audio Coding (AAC) encoder.

SBSMS (Subband Sinusoidal Modeling Synthesis) is software for time stretching and pitch scaling of audio. This package contains the library.

Cuetools is a set of programs that are useful for manipulating and using CUE sheet (cue) files and Table of Contents (toc) files. CUE and TOC files are a way to represent the layout of a data or audio CD in a machine-readable ASCII format.

C.A.V.A. is a bar audio spectrum visualizer for the terminal using ALSA, MPD, PulseAudio, or a FIFO buffer as its input.

The AMB plugins are a set of LADSPA ambisonics plugins, mainly to be used within Ardour. Features include: mono and stereo to B-format panning, horizontal rotator, square, hexagon and cube decoders.

Qsynth is a GUI front-end application for the FluidSynth SoundFont synthesizer written in C++.

Csound is a user-programmable and user-extensible sound processing language and software synthesizer.

audio-to-midi converts audio files to multichannel MIDI files. It accomplishes this by performing FFTs on all channels of the audio data at user-specified time steps. It then separates the resulting frequency analysis into equivalence classes which correspond to the twelve tone scale; the volume of each class being the average volume of its constituent frequencies. This data is then formatted to MIDI and written to disk.

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.
