Track automation
# 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.
