When filming video footage you may wish to also record the audio at the same time but their are a few issues with this and they are...
- The sound of wind
- Background sound
- You can't create perfect silence without a sound proof room (expensive)
- Record sound on a day when there's no wind
- Use wind shields
- Film in a sound proof room
- Record audio separately and edit it in
- Record the audio by having the microphone directly next to the thing producing the sound.
There are different pieces of equipment that are used to record audio and optimism the quality of the audio and they are...
- Lavalier Microphone
The purpose of this mic is to record voice.
- Directional (supercardioid) Microphone
This mic can be used to enhance a particular sound and can diminish background sound.
- Boom Pole (which can be used with the microphones above, man not included)
A boom pole can be used to record sound from a distance as someone can hold it from a distance and point it towards to the production of sound.
- Audio Recorder
An audio recorder can record and playback audio.
- Radio Microphone
A radio microphone is another type of microphone which can record audio.
- Pop filter
A pop filter is an anti-pop noise protection filter for microphones, typically used in a recording studio. It serves to reduce or eliminate 'popping' sounds caused by the mechanical impact of fast moving air on the microphone during recorded speech and singing.
Below I'm going to embed a video explaining what different sounds with in media productions are. These types of audio could either be filmed on or off set.
