In computing, AAC (Advanced Audio Coding) is an audio compression technology that is part of the MPEG-2 standard. It provides a greater compression and superior sound quality than MP3, which is also part of the MPEG specification. AAC is available in three profiles: 'Main', 'Low Complexity' (LC) and 'Scaleable Sampling Rate' (SSR), with 'Main' providing the highest quality. Research AAC
Cool Edit by Syntrillium Software Corporation is a waveform editor for the IBMPC running the Windows operating system with features such as: echo, flange, reverb, stretch/pitch change, compress, brainwave synchronizer, noise reducer, envelope, filter and distortion.
Cool Edit supports batch scripting for automating tasks and supports almost every file format (including mpeg-3 and windows wav), and is used by the BBC for editing radio programs. Cool Edit was first released in 1992 by David Johnston. Research Cool Edit
Free MP3 by Axis Soft is a nice, little MP3-player for the Windows operating system which plays any MP3-file. All mpeg-audio formats are supported, including variable bitrate (Xing alike). You can add your tracks to a play list and arrange the tracks in the play list in any way you like. The play list is Winamp compatible, so you can also use already generated lists. You can add and edit the description of a track (ID3 support). The looks and feel of the player can be changed with skins. A spectrum analyser completes this nice looking MP3-player.

The GIMP (GIMP is an acronym for GNU Image Manipulation Program) is a computer software application that started as an undergraduate project by Peter Mattis and Spencer Kimball at the University of California and has evolved into an application designed for retouching photographs, composing and authoring images. Its powerful capabilities as an image manipulation program make it a worthy competitor to other similar programs such as AdobePhotoshop or Corel PhotoPaint, but the biggest advantage of The GIMP is it's free availability although it's not freeware, rather it is an OSS (Open Source Software) program covered by the GPL license, which gives the user the freedom to access and also to change the source code that makes up the program. The Gimp offers a full suite of painting tools including brushes, a pencil, an airbrush, an ink tool, and cloning. Tile-based memory management so image size is limited only by available disk space; sub-pixel sampling for all paint tools, allowing for high-quality anti-aliasing; full Alpha channel
(transparency) support; layers and channels. Advanced scripting capabilities provided by a procedural database so you can call internal GIMP functions from external scripts, such as Script-Fu, Perl-Fu (Perl scripts) and Python-Fu (Python scripts). The GIMP offers multiple undo and redo, limited only by disk space; transformation tools including rotate, scale, shear, and flip. File formats supported include PostScript, JPEG, GIF, PNG, XPM, TIFF, TGA, MPEG, PCX, BMP and many others. Selection tools including rectangular, elliptical, free, fuzzy, paths, and intelligent scissors. The GIMP supports plug-ins that allow for the easy addition of new functions, new file formats, and new effects filters. The GIMP is probably best known for its use on the GNU/Linux platform, but there are many platforms that GIMP can run on, including GNU/Linux, Microsoft Windows 95, 98, NT4 and 2000, OpenBSD, NetBSD, FreeBSD, Solaris, SunOS, AIX, HP-UX, Tru64, Digital Unix, OSF/1, IRIX, OS/2 and BeOS.

PASC is an abbreviation for Precision Adaptive Sub-band Coding, and is a digital audio encoding method effectively the same as MPEG layer 1 and was used in Philips now defunct Digital Compact Cassette system. PASC divides the digital signal into equally spaced sub-bands and compresses the data to about 1/4th of the original size) Research PASC
VirtualDub is a computer program for the Windows operating system for capturing video with video for windows compatible devices. VirtualDub also offers facilities for fractional frame rates; optimised disk access for more consistent hard disk usage; the capacity to create AVI2 (OpenDML) files to break the AVI 2GB barrier and multiple files to break the FAT32 4GB limit; An integrated volume meter and histogram for input level monitoring; real-time downsizing, noise reduction, and field swapping; verbose monitoring, including compression levels, CPU usage, and free disk space.
VirtualDub enables the user to access hidden video formats your capture card may support but not have a setting for, such as 352x480.
VirtualDub also lets you clean up video on your computer. VirtualDub isn't an editor application; it' s a pre- and post-processor that works as a valuable companion to one: with facilities to read and writes AVI2 (OpenDML) and multi-segment AVI clips and has integrated MPEG-1 and Motion-JPEG decoders. VirtualDub enables you to remove and replace audio tracks without touching the video. Also provided are an extensive video filter set, including blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace, and threshold.
VirtualDub supports decompressing and recompressing of both audio and video, and allows you to remove segments of a video clip and save the rest, without recompressing. Research VirtualDub
