Krecordmydesktop is KDE frontend for recordmydesktop desktop recording software.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes a while. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean.

- radiobutton changed to checkbox in preferences
- when audio recording is disabled, audio quality slicer is disabled too
- better checks in slotRecordmydesktopStdout
- removed encoding on background while user is selecting output file name

rstudio project is a GTK+ GUI that controls programs used in recording, CD mastering, and managing a SHOUTcast server.
The "Radio Station" referred to here is a Shoutcast server. Before you can play any music on the station, you need to either record your own, or use a Peer-to-Peer program or other source to download some music.
The GTK-Gnutella button starts a peer to peer fileshareing program called GTK-Gnutella where you can get a wide variety of music free.
Start Radio station starts up the shoutcast server and its source client, which feeds an mp3 playlist to the server for broadcast.
The playlist file is created when you press the "Close" button in the playlist manager. The playlist manager lets you view either the downloaded files from GTK-Gnutella, or the permanent collection of files. You can select a file, then move it to the permanent collection, only if you are viewing the downloaded files. For either set, you may delete a file, or play it.
Audacity is a very versatile recording tool that can be used to create original content, or to record from other sources, such as a Shoutcast.com station, (or even your own shoutcast station).
Shoutcast.com button starts firefox, with the url of http://www.shoutcast.com so that you may listen to other shoutcast stations, or your own.
Kill XMMS stops any running xmms.
Quit exits rstudio.
GTK-Gnutella starts the P-2-P filesharing system.
K3B can be used to master audio CDs, or even mp3 data CDs that can be played on an mp3-compatible cd player or dvd player.
Enhancements:
- A shuffle playlist button was added.
- The audio player was changed to Audacious since Gentoo does not support XMMS.
- This version was tested on Gentoo AMD64 and Kubuntu 386.
