This is what we learned:

  • Learned different types of audio usage like speeches, music (either live or recorded), talking, film (the soundtrack, sfx and dialogue), podcast, etc.
  • Learned about pitch and frequency, ultrasound and infrasound.

Hertz (Hz) is a unit that measures frequency. The human range of hearing is from 20hz to 22khz. Ultrasound is used in a pregnancy scan and infrasound is what whales and elephants use to communicate with each other.

  • Learned about the doppler effect.

The Doppler Effect is a sound that travels past you. Imagine a car with a droney like sound, the sound changes from right to left.

  • Learned about Foley Sound, Location Sound, Wild track, Voiceover and special effects.

Foley sound – the reproduction of everyday sound effects that are added to visual media.

Location sound – recording all sound on set.

Wild Track – an audio recording intended to be synctonized with film or video but recorded seperatly.

Voiceover – a piece of narration in a film or broadcast.

Special FX (SFX) – are visuals illustrations in a film or images.

  • Learned about audio at home, mono, stereo and surround sound.

Mono means sound from only one direction.

Stereo means sound from left or right of where you are standing.

Surround sound means sound coming from all directions.

  • Finally, learned about what the following equipment are:

Dead Cat – Designed to minimise wind sound.

Broadcast Headset – To communnicate with other crew members on the set.

Shotgun Microphone – a mic that records a more narrow range.

Boom Pole – To record a person strictly without having the mic in the shot.
