The focus of this guide is on the software used to record, capture, manipulate, edit, copy, convert, playback, broadcast, or display audio, video, or audio-video.

Audio, of course, refers to sound. Audio editing software focuses on the creation or refinement of digital sound files and may be known as an audio editor. Some audio editing software is capable of handling only one type of audio formats, such as MP3, while others are designed to work with a wide range of audio file types, which may include MP2, MP3, AIFF, AVI, MPEG, OGG, VOX, WAV, WMA, and others. Some types of audio editors are able to extract audio from audio-video files.

Audio editing software might have only editing functions, while others are capable of other tasks, such as recording, converting, and burning audio to a disc. An audio editor might be a standalone program, but audio editing features are often part of a software application that includes video and image editing capabilities, as well.

Video refers to the recording, reproduction, or broadcast of moving visual images. Generally, a video is a series of digital signals used to generate a steady source of still images, which are played back at a rate that simulates movement. Videos may include graphics, photos, text, of a combination of these, and are usually used for entertainment or educational purposes.

Examples of video formats include 3GP, AVI, FLV, MOV, MP4, and WebM.

Videos may be visual only, but they might also include sound. Videos with sound are usually referred to as audio-video, although it is often assumed that video will include sound today.

Video editing is the process of taking a video clip, or multiple clips and modifying the original to create new media. Although there are many reasons to edit a video clip, the most basic reason is to remove unnecessary or unwanted portions of the video in order to produce a final product that fits into a specific time range. For example, hundreds of hours of film might be cut back to fit into a ninety-minute time slot. It is also common to put together multiple clips in order to create one longer video file.

During the post-production period, several effects may also be added to the video, such as title screens, captions, fade effects, color corrections, and background music.

A video presentation might be as simple as a touch of movement on a webpage or as complex as a professional movie production.
