The GPSTk is an open source C++ library for developing GPS applications.
The GPSTk suite consists of a core library, auxiliary libraries, and a set
of applications. The GPSTk provides a wide array of functions that solve
processing problems associated with GNSS such as processing or using
standard formats such as RINEX. The libraries are the basis for the more
advanced applications distributed as part of the GPSTk suite.
WeatherSpect provides a reasonably accurate simulation of what the weather looks
like outside, in ASCII art. It includes rain, snow, lightning, sleet, and hail.
The windspeed and cloudiness are reflected in the velocity and quantity of
clouds. There are trees that age, reproduce and die over the course of an hour,
and a sun and moon that follow the actual sun and moonrise. There's also a
dancing turtle.
Astro::FITS::CFITSIO is a perl interface to William Pence's cfitsio
subroutine library. For more information on cfitsio, see
http://heasarc.gsfc.nasa.gov/fitsio.
This module attempts to provide a wrapper for nearly every cfitsio
routine, while retaining as much cfitsio behavior as possible. As
such, one should be aware that it is still somewhat low-level, in
the sense that handing an array which is not the correct size to a
routine like fits_write_img() may cause SIGSEGVs.
Grip is a front-end to external cd audio rippers (such as dagrab or
cdda2wav). It also provides an automated frontend for MP3 encoders, letting
you take a disc and transform it easily straight into MP3s. The CDDB
protocol is supported for retrieving track information from disc database
servers. Grip works with DigitalDJ to provide a unified "computerized"
version of your music collection.
MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1
as well as the MPEG-2 extension to Lower Sampling Frequencies. All
three audio layers (Layer I, Layer II, and Layer III a.k.a. MP3) are
fully implemented.
MAD does not yet support MPEG-2 multichannel audio (although it should
be backward compatible with such streams) or AAC, nor does it support
the so-called MPEG 2.5 format.
This is ID3 tag library, which is part of the project.

Sndio is a small audio and MIDI framework part of the OpenBSD project.
It provides an lightweight audio & MIDI server and a fully documented
user-space API to access either the server or directly the hardware in
a uniform way. Sndio is designed to work for desktop applications,
but pays special attention to synchronization mechanisms and
reliability required by music applications. Reliability through
simplicity are part of the project goals.
A real-time signal analysis tool and an offline time-frequency
browser. It has a built in tone generation capability and it can
play back audio files with a multitude of effects and filters.
Designed for environmental analysis missions that range from
modulation parameter measurements to searching for transient signals
that go bump in the night, baudline combines fast digital signal
processing, versatile high-speed displays, and continuous capture
tools for hunting down and studying elusive signal characteristics.
mp3lint is a tool to check collections of audio files for various problems. It
is highly configurable, allowing you to specify your preferred format for
filenames, minimum bitrate, tests to ignore, etc.
Formats checked are currently mp3, ogg, wav, flac, au, and m3u playlists.
mp3lint is implemented as separate tools (perl modules), each of which
implements a set of tests. There are a total of 32 different tests.
Squash is a C/Ncurses based music player. It supports mp3 and ogg through
libraries (and planned flac support). Squash uses statistics to determine songs
to play automatically. It garners this information through whether or not a song
is skipped. Squash also avoids picking the same song twice. Thus Squash is
like a radio station that plays the songs you like -- and you don't even have to
call in requests!
Sexypsf is an XMMS plugin for playing .psf files.
The PSF format brings the functionality of NSF, SID, SPC, and GBS to next-
generation consoles. PSF utilizes the original music driver code from each
game to replay sequenced music in a perfectly authentic, and size-efficient,
way.
The general idea is that a PSF file contains a zlib-compressed program which,
if executed on the real console, would simply play the music.
