Figure 4 - The Navigation and Visualisation of Environmental Audio using Zooming Spectrograms

Other figures that are a part of this publication include: Figure 1 - Top, Figure 1 - Mid, Figure - 4 (Focused stack), and Interactive zooming demo

A sequence of fourteen images from smallest scale (top) to largest scale (bottom) focused on minute 60 (7am). Three-color mappings are used to cover the 11.6 bit scale gap: ACI-ENT-EVN at the smallest scales, BGN-POW-EVN at the mid-scales and the BGN-POW at the large scales (see table).

	Color mapping
Scale	Red	Green	Blue

Mid	BGN	POW	EVN
Large	BGN	Cube-helix color-scale POW
