Free remastering software for linux

Crystality Plugin consists of XMMS plugin and stdin/stdout plugin. It was written for realtime remastering of sound from mp3 files.
You will need a reasonably good stereo and a good ear to notice quality
improvement, otherwise this is not for you.

This plugin tries to patch mp3 format flaws, not a poor audio hardware! Yes, you should be able to hear well enough (sorry) - for some of my friends plugin is a cool thing, while the others does not hear nothing but echo and stereo expander (well, you will hear every effect if you set it to the maximum, but it will not sound nice).

Crystality was written for 16bit 44.1kHz stereo sound and may give strange results
with other sound formats.

Damian Hodgkiss sent me a quick port for Winamp 2.x. I have not tried it yet, but you can get it (cr-quick-winamp-port.zip).

This plugin does mainly four things (and some minor tricks):

1. Adds some sounds in very high frequency range. Most of the mp3s in The Net are flawed with a 16(15?) kHz cutoff. Even these ones compressed at high bitrates. This spectrum hole is audible and very unpleasant. This plugin helps a bit. Old mp3s made from the vinyl or the magnetic tape may also sound better with these "steroids". For old mp3s youll probably need to set filter to 0.1.

2. Adds some even harmonic distortions (actually nonlinearity), that sounds nice. Valve amps introduce even harmonic distortions (although differnt way) Look at audiophile pages for more info (well, mp3 format is not an audiophile stuff at all, but... welcome to the real world...).

3. Adds simple, but nice 3D echo (concert hall or church like). Most of echo plugins sounds too hard and aggresively for me. This one does not.

4. Extends stereo.

USING:

There are currently two versions of plugin - XMMS plugin and stdin/stdout. Stdin/out plugin is completly independent of XMMS plugin. It even stores its configuration in a separate file (~/.crystalityrc). Stdin/out plugin is alpha code, so some features are missed. You cannot reopen configuration dialog after closing without restarting plugin, there are no "save config", "load config" buttons. Configuration is loaded automatically on startup and saved on exit, either on normal finish or ^C. You can disable GUI with -g option (useful in scripts).

Because this plugin adds some sounds at high frequencies, you will probably need to decrease treble level on your amplifier. Plugin does not perform normalization, so you should slightly decrease signal level in XMMS equalizer (NOT volume slider on the main panel). Setting sliders to the maximum is generally a bad idea (well, except the filter, where that setting is useful).

PERFORMANCE:

It eats about 15% of CPU on my AMD K6-2/400 and optimization is still possible, this is not highly optimized code.

INSTALLATION:

Distribution contains binary version of XMMS plugin library and stdin/stdout plugin executable (Linux i586, glibc 2.1.3). You may copy plugin library file (libcrystality.so) into XMMSs Effect directory and executable (crystality-stdio) to /usr/local/bin or any location you prefer. For default locations simply type:

make install

and thats it.
You may also build crystality from the source.

make buildinstall

typed as root in the source directory should be all you have to do.

This plugin was my first small step in gtk programming, so dont expect any wonders, GUI is actually a quick hack to hardcoded settings. I am not a GUI programmer.

WANem is a WAN Emulator, meant to provide real experience of Internet, during development and test on a LAN environment. Typically application developers develop applications on a LAN while the intended purpose for the same could be the client is accessing the application by WAN or even the internet.

WANem allows for the application development team to setup a transparent application gateway which can be made use to simulate WAN characteristics like Network delay, Packet loss, Packet corruption, Disconnections, Packet re-ordering, Jitter, etc.

WANem allows for WAN network characteristic emulation and thus allowing for applications to be tested in a realistic WAN environment before they are moved into production.

WANem is a combined development strategy where it hooks into the Linux kernel for performing network emulations and provides GUI to make it simple to use. Remastering of Knoppix Live CD makes it even more effective as it becomes platform independant.

Mutagenix (myoot-a-jen-iks) -- n. : A dynamic and mutable variant of Linux; Any one of several LiveCDs based on Slackware and Linux-Live.
Mutagenix is built on Slackware Linux and Linux-Live LiveCD build scripts. Slapt-get is the foundation for the Mutagenix build system.
Main features:
- Multiple CDs to choose from. Each is built using the Rescue CD as the base install.
- Starts automatically as a dhcp client.
- Integrated Firewall which auto starts on DHCP networks in stealth mode.
- Slapt-get, with multiple rc files with different sources, is included.
- Cpan2tgz for automatically downloading and installing perl modules.
- Ext2 partitioned USB keys will be mounted as your home dir (/root) so your environment can be saved.
- An xorg.conf on the mounted USB key will be used instead of the default supplied xorg.conf
- Test applications for creating a load across a network. Includes smtp and http sources and sinks.
- Windows password changing utility.
Enhancements:
- Im happy to finally announce the release of Mutagenix 2.6.18.6-2. This release includes a rescue disk (without X) and a KDE disk. This is mostly a bug-fix release to address problems discovered in the installer, but there are several new options available. Of note are the USB installer and a re-worked remastering utility. Mutagenix Features: Slackware 11.0; rescue and KDE 3.5 versions; kernel 2.6.18.6; automatic hardware detection using libdiscover; supports SATA, SCSI and IDE drives; detects and mounts EXT2, EXT3, ReiserFS, XFS, JFS, VFAT and NTFS formatted partitions; customize CD with remastering script; slapt-get, with multiple rc files with different sources, is included; Gslapt, the GTK+ frontend for slapt-get; OpenOffice.org application suite; Mutagenix themes....

Quantian distribution is a remastering of Knoppix, the self-configuring and directly bootable dvd/cdrom that turns any pc or laptop (provided it can boot from cdrom/dvd) into a full-featured Linux workstation.
Recent versions of Quantian are based on clusterKnoppix and add support for openMosix, including remote booting of light clients in an openMosix terminal server context. Earlier releases are still available; see below for URLs for downloads as well as ordering information.
Brief introductory information is available in a paper (from June 2004) submitted to The Political Methodologist, slides from the presentation at Usenix 2004 (July 2004), and in the earlier (revised) paper about Quantian that has appeared in the DSC 2003 Proceedings.
Quantian is an extension of Knoppix and clusterKnoppix from which it takes its base system of around two gigabytes of software, along with fully automatic hardware detection and configuration.
Enhancements:
- Kernel 2.6.12, KDE 3.5 / 3.4, OpenOffice 2.0, ... and more from Knoppix 4.0.2
- a backport of the openMosix-enabled 2.4.27 kernel and openMosix tools from the last clusterKnoppix release,
- very comprehensive support for GNU R with over 870 packages from CRAN and BioConductor, plus ESS, Ggobi, Rpad, RKward, RSPerl, JGR, ...
- addition of the Java 1.5.0 SDK enabling us to add ImageJ, Weka, JGR, Mondrian;
- plus a number of other new packages (inkscape, orsa, praat, wxmaxima, some more Debian documentation...)
- and still loads more of math, bio, engineering, LaTeX, ... software
