Unit 73 - Sound
Unit 73 - Sound:
Aircon
white noise
ocean
- Sounds are made from sine waves.
- The medium is the air.
Wave length = from one starting point to another same point
Wave length is measured in frequency/Hz (how frequent it occurs)
Amplitude is measured in Lambda
Human's can hear from 20 Hz - 20 KHz
Waves lengths = how many times you hear it per second, if you hear something 500 times in a second then its 500Hz
Middle 'C' Hz = 261Hz
Violin
Piano
Timbre = Tone Colour (quality of the sound)
Vibrations of harmonics at the same time producing the pitch.
Timbre (tone quality, color) is what differentiates two sounds in the same frequency (same note). For example, the Do (C) note played in a guitar has a really different sound of a Do (C) when played in keyboard or flute. This means that these instruments have different timbres.

Loudness = level of sound. Measured in dBs.
Voice = 5.5PPM
SFX = 4.5PPM
Music = 3.5PPM
Avoid Distortion. https://www.youtube.com/watch?v=40aU-YkNDHw here is an example of distortion in a audio clip.
Sound source = pressing of a key, your feet steeping on a surface which can be used in Foley etc...

League of legends showcase of voice lines and game sounds - https://www.youtube.com/watch?v=m-7H0GrQOlw
in the league of legends clip above lots of game sounds have been used to create some music however this video is a great way to display loads of the games sounds, for example it have some of the weapon attack sounds which would've been created using foley and there are other sfx sounds in there too, these sounds would've probably been recorded in a foley studio and then edited using specialist software, such as audacity, https://wabisabisound.com/services/, this link here is to wabi sabi sounds they create sound, music and other audio services for game companies they have produced the audio for the opening cut scene for COD Modern Warfare 2, they have also produced all of the music for farmville, they use professional grade recording hardware and some of the best recording software money can buy to produce the best quality sound for video games in the game sound designers video above there are examples of their work.
Purpose of game sound-
- Atmosphere
- immersive (gun needs sound)
- brings game to life
- Sound to force player to feel
- Character definition
- Inform Player
Examples of game audio:
- People's ultimate in League of Legends (Sion ult is heard by all players when activated) https://www.youtube.com/watch?v=UABavbQjyNM
- Sonic coin pickup - https://www.youtube.com/watch?v=FRgfAPe5s3U
- Super Mario "Yahoo" - https://www.youtube.com/watch?v=NjA0Cmxm4wc
- Mortal Kombat game music - https://www.youtube.com/watch?v=H_Nm3kjLkH4
Psychology:
Sounds need to be balanced
What sounds do you need to create calm:
Music- for the music this will be the background setting to create a calm atmosphere
flutes - https://youtu.be/xu2pESvXcmM?t=396
high pitch
major key
SFX - the sound effects of the trees and birds will make the scene feel a lot more immersive which will make them feel more calm
soft wind - https://www.youtube.com/watch?v=4KzFe50RQkQ
leafs rustling - https://www.youtube.com/watch?v=qVFasUmGztwbirds tweeting - https://www.youtube.com/watch?v=eMWeQWGla0Y
Voice - then having a calming voice, like gandalf, it will calm the player more
calm warm voices https://www.youtube.com/watch?v=dG2UO2F0iY4

League of Legends audio environment:
I-nterface = ping sounds in league of legends, the menu sounds in the shop when you buy items https://www.youtube.com/watch?v=RSmCwy1eqSk
E-ffect = Spells effects https://www.youtube.com/watch?v=FtTm8Zh5UPE
Z-one = Ambient jungle sounds https://youtu.be/JoM1YxRCLDM?t=117
A-ffect = DJ Sona's background music https://www.youtube.com/watch?v=mgLTNCMzd9Y
One of the main sound designers for league is Adam Swanson.

On this link you can see all of his work to do with the game.
Sound sources:
- Company source library (buy)
- Foley (buy)
- Voice acting (buy)
- Software - Audacity, logic, garage band, adobe audition
I - i would source the sound for interface through sound libraries because i could find lots of basic sounds which would work well in a H.U.D https://sonniss.com/sound-effects/
E - i would use foley do source the effects for the game https://wabisabisound.com/services/
Z - for zone i would also use a sound library to source the background sound for my game
A - for affect i would use software to create the music for the game. https://www.nch.com.au/mixpad/index.html?kw=logic%20music%20software&gclid=CjwKCAjw_MnmBRAoEiwAPRRWWzq-Pb0FbsBg9TysB6MXITyb8_IeS8m8P4Fw5y7ulYmz2QQw4CbPCBoCjgkQAvD_BwE
Microphones:
- Rifle mic
- Shot Gun
- 416
- sm58

Room sizes:
Ideal dimensions for recording rooms can be calculated by using the following ratios: #1 Small rooms> Height=1, length=1.6, width=1.25. In other words, to build a small music studio, the ceiling should be 10 feet, the width 12 1/2 feet and the length 16 feet.How to record game music:
- Plan
- Room
- Chairs which don't produce sound
- Software
- Instruments directly connected to computer
- Sm58 Microphone to record vocals
- Lyrics
- Vocalist
Sound files for game:
Lossless:
- .wav (PC friendly)
- .aif (MAC)
- .flac
Lossy:
- ac3 (lossy/Dolby 2.0)
- .mp3
- .ogg
Limitations:
- Time
- Money
- Brain
Hardware:
- R.A.M - 32Gb
- C.P.U - AMD thread-ripper 2
- Hardrive (S.S.D)
Software:
- Gamemaker
- pro tools
- Antivirus
- Adobe
- Pro Tools
- Logic
G.D Speaker:
- Bose
- WharfeDale
- Denon
Small = Tweeter (high frequency/trebble)
Medium = Mid-range speaker
Large = Whoofer (low frequency/Bass)
Headphones:
- Razer
- Steel series
- Corssair
- etc...
Bad headphones = bad immersion (Sony - V150 Headphones)
Good headphones = good immersion (Astro a50)
Good speaker and headphones avoid distortion.
Size matters:
- Lossless = under 500Mb
- Lossy = under 50Mb
If i wanted to capture a gun shot for foley i would record it with a cardioid microphone so that i only get that one specific sound, this will export a .flac, once it's recorded i'll check the sound on WharfeDale speakers to check if it needs to be recorded again, then it'll be edited in pro tools and then it will be put into adobe media encoder where it will then be compressed to a .mp3.
Legal issues:
- Copyright
- PEGI rating
GTA uses explicit language such as racist and other bad language.
The ESRB's ratings page for GTA 5 lists its potentially objectionable material as including: Blood and Gore, Intense Violence, Mature Humor, Nudity, Strong Language, Strong Sexual Content, and Use of Drugs and Alcohol.
Retail stores are not supposed to sell games to youths younger than a game's rating without express consent from a parent or guardian.
GTA advise that children should not play this game because of all of the points above. for example above some of the example material is things like strong language and intense violence and the sound which is associated to this also adds to the rating
Voice:
- U - 'Infrequent use only of very mild bad language'
- PG - 'Mild bad language only'
- 12A/12 - 'Moderate language is allowed. The use of strong language (for example, ‘fuck’) must be infrequent'
- 15 - 'There may be frequent use of strong language (for example, ‘fuck’). The strongest terms (for example, ‘cunt’) may be acceptable if justified by the context. Aggressive or repeated use of the strongest language is unlikely to be acceptable'.
- 18 - No constraints on language
