Computer system for manipulating audio From Wikipedia, the free encyclopedia
Audio editing software is any software or computer program which allows editing and generating audio data.[1] Audio editing software can be implemented completely or partly as a library, as a computer application, as a web application, or as a loadable kernel module. Wave editors are digital audio editors. There are many sources of software available to perform this function. Most can edit music, apply effects and filters, and adjust stereo channels.
A digital audio workstation (DAW) is software-based and typically comprises multiple software suite components, all accessible through a unified graphical user interface. DAWs are used for recording or producing music, sound effects and more.[2]
Audio editing software typically offer the following features:
Typically these tasks can be performed in a manner that is non-linear. Audio editors may process the audio data non-destructively in real-time, or destructively as an "off-line" process, or a hybrid with some real-time effects and some offline effects.
Audio plug-ins are small software programs that can be "plugged in" to use inside the main workstation. Plug-ins are used in DAWs to allow more capabilities when it comes to audio editing.[3] There are several different types of plug-ins. For example, stock plug-ins are the plug-ins that come already installed with a DAW, and Virtual Studio Technology (VST) plug-ins. Invented by Steinberg, VST plug-ins allow producers to apply simple or advanced effects such as filters, limiting, compression, reverb, flanging, panning, noise reduction, and equalizers.[3]
MIDI (pronounced "middy") and audio are both compressed digital formats that are used within a Digital Audio Workspace (DAW). MIDI stands for Musical Instrument Digital Interface. MIDI is used with plug-ins that allow the user to control the notes of various plug-in instruments. MIDI is universally accepted and if one plug-in or synthesizer is used using MIDI, then it can be modified with another synthesizer.[4] The filename extension of MIDI format is .MIDI or .MID.[4] Unlike MIDI, Digital audio contains a recording of sound. Audio files are a lot larger than MIDI files, and while MIDI is smaller, MIDI can have variations from the original sounds.

Destructive editing modifies the data of the original audio file, as opposed to just editing its playback parameters. Destructive editors are also known as sample editors. Destructive editing applies edits and processing directly to the audio data, changing the data immediately. If, for example, part of a track is deleted, the deleted audio data is immediately removed from that part of the track.
Real-time editing does not apply changes immediately but applies edits and processing on the fly during playback. If, for example, part of a track is deleted, the deleted audio data is not actually removed from the track, but is hidden and will be skipped on playback.[5]
