PP3 creates celestial charts. It generates resolution independent maps of very
high graphical quality. They can be used for example as illustrations in books
or on web pages. You may use own databases or free ones from the Internet.
astLib is a set of Python modules that provides some tools for research
astronomers. It can be used for astronomical plots, some statistics,
common calculations, coordinate conversions, and manipulating FITS images
with World Coordinate System (WCS) information through PyWCSTools - a
simple wrapping of WCSTools by Doug Mink. PyWCSTools is distributed (and
developed) as part of astLib.
This program generates, but does not display, image files containing
raster maps of the Earth. It includes public-domain, vector data from
which they are drawn, describing the continents, bodies of water,
boundaries of countries and U.S. states, and a few cities. Command-line
options allow centering the maps at a particular latitude and longitude
and zooming in.
RoadMap is a program for Linux that displays street maps. The maps are
provided by the US Census Bureau, and thus only cover the US.
RoadMap is at an early stage of development. At this time there are no
routing features implemented yet. RoadMap can only display the map around
a specified street address or follow a GPS device (using gpsd). The plan
for the future is to implement some navigation features similar to those
found in commercial street navigation systems.
RoadMap uses a binary file format for representing the maps that is compact
enough to allow the storage of many maps on a Compact Flash or MultiMedia
card. The map of Los Angeles county takes about 10 Mbytes of flash space.
RoadMap comes with a set of tools to convert the US Census bureau data
into its own map format.
Xplanet was inspired by Xearth, which renders an image of the earth into the X
root window. Xplanet uses the Imlib library to read user supplied maps of the
earth (or another planet). Orthographic and Mercator projections can be
rendered to the root window or saved to a file. An image that the user can
rotate interactively can be popped up in a window using OpenGL or Mesa.
AMPLE is short for "A MP3 LEnder"
So what's good with AMPLE?
Small, standalone (written in C using no external libraries)
Allows you to listen to your own MP3's away from home,
nothing more, nothing less
Aqualung is an advanced music player originally targeted at the GNU/Linux
operating system. Today it is also running on FreeBSD and OpenBSD, with
native ports to Mac OS X and even Microsoft Windows. It plays audio CDs,
internet radio streams and podcasts as well as sound files in just about
any audio format, and has a feature of inserting no gaps between adjacent
tracks.
The Analysis & Resynthesis Sound Spectrograph (formerly known as the Analysis &
Reconstruction Sound Engine), or ARSS, is a program that analyses a sound file
into a spectrogram and is able to synthesise this spectrogram, or any other
user-created image, back into a sound.
ARSS is now superseded by Photosounder, which makes use of most of the
techniques offered by ARSS in a simple to use and powerful graphical user
interface and built in editor.
The asmix utility is a volume control knob for X windows and for AfterStep
window manager especially. The knob can be used to adjust the master
volume of your sound card.
Audiere is a high-level audio API. It can play Ogg Vorbis, MP3,
FLAC, uncompressed WAV, AIFF, MOD, S3M, XM, and IT files. For audio
output, Audiere supports DirectSound or WinMM in Windows, OSS on
Linux and Cygwin, and SGI AL on IRIX.
Audiere is open source and licensed under the LGPL. This means that
you may freely use Audiere in commercial products, as long as you
do not modify the source code. If you do modify Audiere and release
a product that uses your modifications, you must release your changes
to the code under the LGPL as well.
Audiere is portable. It is tested on Windows, Linux-i386, Cygwin,
and IRIX with at least three major compilers. Most of Audiere is
endian-independent, so I expect it would work with few modifications
on other architectures.
