Jargon Buster Part 3 – Audio & Video Files: 12th August 2019

This is the third and final article by Mark Smith our Director of Technology here at Duplication Centre; helping you to understand some of the terminology and abbreviations used in the industry.

Audio Files:

Unlike the disc image formats above, these are just individual audio files used by computers. They require ‘Authoring’ to a disc. Authoring a CD means taking the audio (in any of the formats) and writing it into a format and structure a simple CD player can understand and play

WAV

These are high quality audio files, very similar to standard CD-Audio. This is a very common format used in recording studios .

AIFF

AIFF is practically identical to WAV, but this format was developed by Apple in the late 80’s. Another very common format in recording studios.

MP3

This is a digital music format created for sending audio over the internet. The great attraction of the MP3 format is its ability to compress files, allowing them to use much less space. Technically lower quality than the above audio formats, but not really in any noticeable way

FLAC

The Free Lossless Audio Codec. This is a newer format which is able to compress audio to take up space just like an MP3, but does so in a ‘lossless’ way. This means the audio quality should not be degraded  in any way, but the file size will be noticeably smaller. A useful format that has only seen uptake in technical and audiophile community.

Video Files:

This section may appear a bit short, but I had to draw the line somewhere.  There are a very large number of video formats that have existed over the years, far too many to discuss here. In practice there are 2 very common ones.

All video formats will require ‘Authoring’ to make a standard DVD-Video disc (OR a Blu-Ray-Video disc) to be player in a standard player.  Simply burning a video file on a disc will not necessarily allow it to play in a standard player.

MP4

A modern high quality video format widely used in consumer and professional markets.

MOV

Another modern high quality video format widely used in consumer and professional markets. Developed by Apple.
