Audio Components: Presentations

Audio in presentations is pretty much similar to how things are recorded and edited in studios. if presenting to a large audience the speaker or speakers is often hooked up with a microphone that plays through speakers set up around the room/hall. these must be regulated so that the sound is crisp and understandable, without huge amounts of echo or interruption. The presenter often uses a handheld mic with a cable or a transmitter that sends out the sound to the speakers, or a clip on mic, which is hands free and also sends off the audio via a transmitter. This eliminates the need for a sound recording crew with a boom pole to record audio.

Often with presentations there is a slide show or a video that is played on a screen. This slide show or video often includes sound. this sound is also played through some sort of speakers, but the levels of the audio must be checked beforehand so that the loudness, bass and clarity of sound is correct.

Because this is often a live event, there isn't much editing, if any at all needed for the presentation, as the audio is produced in real time to an audience. This may change however, if the presentation is recorded. the audio from both the speaker and the video/presentation must be mixed so that both are easily identified when played. Sometimes, if a presentation is being filmed, the sound team will place a number of microphones around the crowd to pick up background audio and possibly even audience questions or replies.
