For each reference a brief summary is reported, usually taken from the Web site that describes the product or demonstration. Some programs and demos are old, and there is no guarantee they will continue working, or they will work with all operating systems and browsers. Please report any misbehavior to the course teacher.
GIMP - The GNU Image Manipulation Program
GIMP is the GNU Image Manipulation Program. It is a freely distributed program for tasks as photo retouching, image composition and image authoring, much as the commercial program Adobe Photoshop. It works on several operating systems, and the interface is available in many languages.
A Java applet that demonstrates the effect of quantization on JPEG image compression.
JPEGsnoop is a free Windows application that examines and decodes the inner details of JPEG and MotionJPEG AVI files. It can also be used to analyze the source of an image to test its authenticity.
Audacity® is free, open source software for recording and editing sounds. It is available for Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems.
Wavosaur is a free sound editor, audio editor, wav editor software for editing, processing and recording sounds, wav and mp3 files, with some interesting features for sound spectral analysis. It works on Microsoft Windows operating systems.
A set of audio files showing different coding and compression quality. The set is composed of zipped archives containing audio recordings at different sampling and quantization rates, or compressed at different speed. The archives and filenames are representative of the audio features.
MPEG Streamclip is a powerful free video converter, player, editor for Mac and Windows. It can play many movie files, not only MPEGs; it can convert MPEG files between muxed/demuxed formats for authoring; it can encode movies to many formats, including iPod; it can cut, trim and join movies. MPEG Streamclip can also download videos from YouTube and Google by entering the page URL.
FFmpeg (Source code), FFMpegX (Mac OSX), Winff (Linux, Windows)
FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It includes libavcodec - the leading audio/video codec library.
VcDemo is an interactive image and video compression free-ware software package for Windows.
It is intended as a tool for learning about compression techniques: from basic sampling and PCM to today's most advanced scalable embedded zerotree wavelet image compression technique, and the MPEG video compression standard.
VirtualDub is a video capture/processing utility for 32-bit and 64-bit Windows platforms (98/ME/NT4/2000/XP/Vista/7), licensed under the GNU General Public License (GPL). It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.
