Audio Issues: Theory, Practice and Post-Production
by Mark Skipper and Todd Dadaleares
The goal of this workshop was to provide a hands‐on experience to help learners identify common audio issues, suggest methods for fixing those issues, and discuss strategies on how to improve the realism of live and recorded simulation audio using the best hardware and software.
Common issues discussed include: background noise; the entire video, or a single participant, is too loud or too quiet; the video and audio are out of sync, equalization, choosing the best microphone, pre- and post-processing.
Goals for the workshop:
• Recognize common audio problems ‐‐ not only that there is a problem, but what the problem is
• Understand common audio‐editing tools, including Digital Audio Workstation (DAW) software as well as common tools such as compression, noise gates, high‐ and low‐pass filters, and EQ, and know how to determine which tool is the best tool for the job.
• Learner will be able to understand the nature of audio, how it travels, what causes feedback and how microphones and speakers work.
• Learner will be able to discern differences in microphone types based on technical specifications‐ and to properly choose correct microphones/mixers or equalizers for particular productions. Participants will understand how and why certain sounds can or can’t be recorded well and why.
• Learner will walk away with knowledge of audio data compression types, their strengths and weaknesses and also understand what analog audio compression is and how, why, when and whereto potentially use it in simulation productions.
• Learner will gain an understanding of the importance of excellent audio and clear, controllable,“compressed” vocals in medical simulation. Participants will understand the need for the best audio quality possible and how to assess when additional gear and techniques might be required.
• Learner will acquire knowledge about audio mixers, some audio gadgets, live voicing techniques and the importance of vocal performance commitment.
• Learners will leave with a list of recommended vendors, equipment and materials for researching about and recording audio in multiple forms.
