Sound for Computer Games - Psychology of Sound

What is timbre?

Timbre is the quality of a musical note of sound or tone that distinguishes different types of sound production, such as voices and musical instruments.

List 3 games or films which use sound as information (speech, iconography, symbolism and/or metaphor) to convey information.

Over the Hedge (Film) uses a firefly which flies around a characters head, and lights up when a character gets an idea, which is a parody of the light-bulb idea, and is accompanied by a "ding" of a triangle. The light bulb has been used numerous times, and has become iconic, and recognisable. 

Super Mario Bro's game uses a chime when the player collects a coin. Quickly became iconic and used in other platform games.

Mario Kart game countdown to the race on the wii featured three beeps, followed by a higher pitched, longer tone, symbolising the start of the race.


Audio Atmosphere

3D audio - 3D audio is improved surround sound technology. It features sound that not only plays from in front and behind, but also beside, and even above/below. 3D audio can be used with headphones, which act as surround sound speakers, playing sound in one ear, where the sound is coming from.

Surround Sound - Surround sound has 5 or 7 speakers, set up around the room. This makes the sound come from the speakers behind or in front, depending on what sound is playing, and where the sound is coming from, in relation to the centre point (a person, or the middle of the screen etc). This gives an immersive experience from your own home.

Interactive adaptive sound - This is when music or sound effects adapt to the players inputs and gameplay. For example, the background music changes when the character stops exploring, and starts fighting etc. It also adapts to movement, for example, if you step on concrete to wood etc.

Sound for Computer Games - Exercise 1

              Creates a dark/sad atmosphere. An air of mourning.
              Anticipatory.

Why is music and sound FX important within a games development?

Music and sound is used in video games to create a mood and atmosphere, which represents the story/genre of the game. For example, a fast paced piece of music, creating suspense and tension.

Wavelength - Sound wavelength is measured in metres, and is the distance from any point on one wave, to the same point on the next wave.

Amplitude - The amplitude of a wave is the distance from the centre line of a wave, to the top of the crest, or the bottom of the trough. The greater the amplitude, the higher the energy it is carrying.

Frequency - The frequency is how many waves passing a point at a certain time. It is measured every second, in hertz (Hz). One wave every second is 1Hz, and so forth.

Decibel level - The decibel level is how loud a sound is, and is measured in dB. A watch ticking is less than 20dB, and a shotgun blast is over 140dB. Short term exposure at 150dB can cause permanent damage to the human ear.


What is Foley?

Foley is a process in which sound effects are added to movies, post production. Sounds are recorded in 'Foley studio' (specialized sound studio), and added into the production by a Foley artist. Foley sound effects commonly used are footsteps,  paper folding, doors opening, and glass breaking, among many more.
