A Forensic Database for Digital Audio, Video, and Image Media
THE “DENVER MULTIMEDIA DATABASE”: A FORENSIC DATABASE FOR DIGITAL AUDIO, VIDEO, AND IMAGE MEDIA by CRAIG ANDREW JANSON B.A., University of Richmond, 1997 A thesis submitted to the Faculty of the Graduate School of the University of Colorado Denver in partial fulfillment of the requirements for the degree of Master of Science Recording Arts Program 2019 This thesis for the Master of Science degree by Craig Andrew Janson has been approved for the Recording Arts Program by Catalin Grigoras, Chair Jeff M. Smith Cole Whitecotton Date: May 18, 2019 ii Janson, Craig Andrew (M.S., Recording Arts Program) The “Denver Multimedia Database”: A Forensic Database for Digital Audio, Video, and Image Media Thesis directed by Associate Professor Catalin Grigoras ABSTRACT To date, there have been multiple databases developed for use in many forensic disciplines. There are very large and well-known databases like CODIS (DNA), IAFIS (fingerprints), and IBIS (ballistics). There are databases for paint, shoeprint, glass, and even ink; all of which catalog and maintain information on all the variations of their specific subject matter. Somewhat recently there was introduced the “Dresden Image Database” which is designed to provide a digital image database for forensic study and contains images that are generic in nature, royalty free, and created specifically for this database. However, a central repository is needed for the collection and study of digital audios, videos, and images. This kind of database would permit researchers, students, and investigators to explore the data from various media and various sources, compare an unknown with knowns with the possibility of discovering the likely source of the unknown. -

Start MP3 Audio Mixer SoundWarrior double clicks the MP3 Audio Mixer icon on his desktop. Okay, we could have left this step out. J 2. Drag in some sounds. SoundWarrior has a good sound of a cave-woman scream called arghhh1.wav. The sound is located in "c:\cavescreams\", which he finds, and then drags the sound’s icon onto the MP3 Audio Mixer window. See working with sounds. 3. Drag in some more sounds. SoundWarrior also drags in stampede.wav, the sound of a herd of Mastodons stampeding by his cave. Finally, he drags in an MP3 called "rockrolls.mp3", some of the latest music from "The Stoners" 4. Make a recording if you want. SoundWarrior hits the record button and the record dialog comes up. He punches the record button on the dialog and screams into his microphone "You make fire now! I make fire yesterday!" He then hits the stop button, previews the sound and saves it as "me_talk1.wav". -

(A/V Codecs) REDCODE RAW (.R3D) ARRIRAW
What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format.
