# Tracks and Busses

This chapter covers basic management of tracks. Tracks are probably the most important objects in Ardour. They represent the fundamental way to playback and record audio, MIDI, and image data.

## Hiding Tracks

The track list on the left edge of the Editor and Mixer can be used to hide or show specific tracks in either or both of those two windows. To hide a track, click to on the tracks name in the relevant track list. To show a track, click on its name in the track list. Visible tracks have their names shown in cyan, hidden ones in orange.

You can also hide any track by clicking its hide button (images/hidebutton.ps).

Hiding a track in the Editor has no effect on its visibility in the Mixer, and vice versa. Hiding a track in one or both windows does not affect the playback of that track's material.
