Moodbar is a computer visualization used for navigating within a piece of music or any other recording on a digital audio track.

If the audio is a speech or an interview then the moodbar displays different speaking segments in unique colour combinations.

Moodbar was originally presented by Gavin Wood and Simon O’Keefe in their paper On Techniques for Content-Based Visual Annotation to Aid Intra-Track Music Navigation.

As of 2008, the default implementation of Amarok's moodbar only uses the spectral content of the current section of the track.

It calculates the energy in the low, medium, and high frequency bands, and turns this into the amount of red, green, and blue in the corresponding stripe.
