  • Uncompressed Audio File Formats

    This document summarises the main features of uncompressed audio file types, including WAV, AIFF and Broadcast WAV (BWF). It gives an overview of these 'raw' formats, and a simple explanation of the common options they will offer the user when creating or working with digital audio. It also looks at lossless compression tools for subsequently reducing the size of these files which will allow reconstruction of their original audio data sonically unaltered. Several sections include links to further resources covering specific relevant topics in more detail, so this is a good place to start if you want to learn more about any of these formats.

  • Building Effective Screencasts

    Screencasts - videos of on-screen computer activity, accompanied by voice-over, and possibly other media (webcam video, Powerpoint slides etc) - have in recent times increased massively in popularity, scope and acceptance, and can now provide a sophisticated learning experience, incorporating slides, images, video, audio, screen annotation, subtitles, interactive quizzes and more.. Whether you want to narrate a presentation, demonstrate the use of software, or record and share your screen for any other reason, a screencast may well be the answer.

    This practical one-day workshop provides an opportunity to learn how to maximise the value of screencasting in presentation, demonstration and digital storytelling for teaching and learning, in the context of the whole workflow from planning your own short screencast to rendering it as a video. We've even had some delegates posting finished screencasts to YouTube by the end of the day!

  • Digital Media Restoration (Audio-Visual only)

    Analogue media deteriorates at an alarming rate and few digitisation projects can hope to retrieve great signals from aged collections. In order to archive maximum usefulness some basic digital remastering is often required. Fortunately, today's digital tools mean we can easily remove unwanted 'defects' whether hisses and scratches from shellac discs or the distorted colours of old videotapes

    N.B. This course covers digital restoration of audio-visual resources only. It does not cover restoration of still images
