MP3 (Audio)
| File extension | .mp3 |
| Category | Audio File |
| Description | MP3 is a digital music format which allows CD tracks to be reduced to around a tenth of their normal size without a significant loss of quality. MP3 gets rid of a lot of the information recorded in a song that our ears are not able to hear and then uses complex algorithms to reduce the file size. This then enables you to get hundreds of songs on to a CD and it also has opened up a new market over the internet - the download market as download times have been significantly reduced. |

| Technical Details | The MP3 format is a lossy format. That means that an MP3 file does not contain 100% of the original audio information. Instead, MP3 files use perceptual coding. In other words, that means it removes the information that your ear doesn't notice thereby making the file smaller. The reason lossy formats are used over RAW is that RAW audio files are too large to travel over the internet at any great speed. By using lossy formats it enables even dial up users to download mp3 files at a reasonable speed. RAW file formats generally require 176,000 bytes per second compared to a lossy format which requires 17,600. The difference is massive and so are the download times. |

WAV (Audio)
| File extension | .wav |
| Category | Audio File |
| Description | The WAV file is one of the simplest digital audio file formats. It was originally developed back in 1991 for use within Windows 3.1 but today it is the gold standard in studio recording and one of the most popular digital audio formats. As they are stored in an uncompressed format they are enormously versatile and allow for easy editing and manipulation. One minor drawback is that the file sizes can be huge which can make them a little impractical. |

| Technical Details | A file with the WAV file extension is a Waveform audio file format and is a container that stores data in segments. It was originally developed by Microsoft and IBM and stores uncompressed lossless audio which results in very large file sizes. The format uses containers to store the audio data, track numbers, sample rate and bit rate. |
