                      L3 Extended Diploma in Games Design

                      Unit 73: Sound for Compute Games
 

Aims:

P2 Understand the methods and principles of sound design and production

Research and explain when you would use the following sounds format and why?

Sound file formats:

Uncompressed: WAV (Waveform Audio File Format) is Microsoft’s native uncompressed audio format for Windows. Though a flexible format which is capable of storing very high quality audio, WAV has a few limitations which have become apparent over its lifetime, and extensions to the format have been developed to address them. AU (Audio file format) which was introduced by Sun Microsystems. The format was common on NeXT systems and on early web designs. SMP (Smart Music Performance file) is used for bands, orchestra, and voice; saves an accompaniment that can be used for practicing. It also includes the sheet music information and can be sued for assessment; replaced by the .SMPX in Finale 2014. VOC (Creative Labs Audio File) is used by Creative labs hardware, such as SoundBlaster sound cards; may be audio clips, sound effects, or instrument sounds, which also referred to as voice; VOC files are compressed to reduce file size.

Compression: e.g. mp3 is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. RA (Real audio) it was first introduced by Real Networks in 1995, the current version being Real Audio 10. It is used as a streaming audio format due to its ability to conform to low bandwidths. This makes it a common format for many internet radio stations. VOX () is a file extension for an audio file used with Voxware software. VOX files contain MetaVoice audio data simulating human speech, based on Dialogic ADPCM codec. VOX files can be opened and edited using the Voxware MetaSound codec.
