text: # Track automation
  
  Track automation or sometimes only automation refers to the recording or handling of time-based controlling data in time-based computer applications such as digital audio workstations, video editing software and computer animation software.
  
  ## Some Examples
  
  ### Multitrack audio software
  
  In modern DAWs every parameter that exists can usually be automatised, be it settings for a track's volume, applied filters or a virtual instruments. Either the user turns some knobs/faders/etc on a physical controller connected to the computer or the user can set keyframes with the mouse, between which the computer interpolates, or the user can draw entire data curves.
  
  Some examples:
  
  * The volume of a track can sometimes or constantly change (fade-in/out/over)
  * The panning of a sound might change
  * A filter sweep (more or less intensive filter, or the frequency limits might change)
  
  ### Animation software
  
  The user sets some keyframes for i.e. position/rotation/size of an object or the position/angle/focus of a camera, and this movement data can be altered over time.
  
  ### Video editing software
  
  Blending between 2 clips. The track automation curve affects how one image changes into the other, be it slow/fast with/without acceleration, maybe even back and forth if one uses a Sinus-like wave.
