P2: Understand the methods and principles of sound design and production
Sound Formats

Exercise 1

People would use uncompressed files in order to get more quality however it takes up much more space which means it isn't a viable option for things such as Mp3 players or phones.

People use Lossy compression in order to reduce the file size which is has less quality but is a more viable option for Mp3 players or phones.

Audio Sampling
1)Resolution can constrain a file size by using more or less pixels to get varying levels of quality and file size. Bit Depth can constrain a file size by using more or less "bits" of information to increase or decrease the quality and file size.

2)Sample Rate: The number of audio samples carried per second by the audiofile.
   
Mono: Sound that is intended to be played through one speaker.
  
 Stereo: Sound that is intended to be played through two speakers which are usually for sounds that are supposed to be heard through either the left or right ear.

  Surround: When Sound is played through three or more speakers which can be used to make the sound seem more immersive for example in a film with surround sound you may hear a car that sounds like its behind you however its just due to the sound being played by speakers that are behind you.

Exercise 2:

Audio Limitations of Game Platforms

DSP(Digital Signal Processor):Can filter and compress the sound which limits the recording

RAM(Random Access Memory):RAM can limit the recording of sound by storing the info in a lossy format

File Format(Mp3, Wav, Aiff):This can limit the recording by using a lossy file format which has less quality

Audio Output(Mono,Stereo,Surround):This can limit the recording of sound if you use stereo or mono sound because it uses less channels.

PCM(Pulse Code Modulation): Can limit the recording of sound by compacting the information onto discs which compresses the information. takes a sample of an audio file which is higher quality
Audio Recording Systems

Multi Track Recording can be used to mix sounds and music tracks together.
Midi(Multi Instrument Digital Interface) can be used to replicate musical instruments digitally
DAT(Digital audio tape) can be used to record the sounds around you
Analogue is made from variations of air pressure
Software Plug-ins can be used to add a feature to a piece of software
