Multitrack audio software
In modern DAWs every parameter that exists can usually be automatized, be it settings for a track's volume, applied filters or a virtual instruments.Either the user turns some knobs/faders on a physical controller connected to the computer or the user can set keyframes with the mouse,[1] between which the computer interpolates, or the user can draw entire data curves.[2]
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.
