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.

  • Audio and Video Standards for Online Learning Kevin Reeve, Utah State University
    ... from the Dr. C Library Audio and Video Standards for Online Learning Kevin Reeve, Utah State University Introduction Digital media is a powerful tool that can enhance your online course. Recent devel- opments and market trends have changed the rules and media formats that need to be considered when creating media for your course. Choosing the correct video and audio format is the first step to insuring a successful experience for both instructor and student. Podcasts, a form of digital media meant for downloading to a portable media device are included in this discussion. Video and Audio Formats Popular media formats for audio and video include RealAudio® and RealVideo®, Win- dows Media®, MPEG 3, and MPEG 4. Each requires software that will encode video/ audio to that format, and also a player that will decode the video/audio for playback. All these formats are currently being used in e-learning with great success. The latest market trends are now suggesting that MPEG 4 for video and audio and MPEG 3 for audio only are “the” standards for digital media. Why MPEG 4 and MPEG 3? MPEG 4 and MPEG 3 are the standard because of consumer response. Apple ad- opted MPEG 4 early on as the video format for playback on their iPod®s that support video. Apple and YouTube worked together to allow YouTube video to be accessed by an Apple TV®, iPhones®, and the iPod® Touch. YouTube moved from Flash Video to MPEG 4 to accommodate these devices, and Adobe soon followed by updating its Flash Player to play MPEG 4 video and audio.
