A multifractal is a field with fluctuations or structure at all scales. Many natural objects such as clouds or mountains are multifractal. The Sonifier enables these fluctuations to be heard as different frequencies by interpreting the field as a sonic waveform. Two-dimensional fields are "unstacked" row-by-row to construct a single long-running waveform. Because the two-dimensional fields are periodic, this unstacking introduces a "drone" sound corresponding to the jumps from one row to the next.

The parameter H controls the relative loudness (power) of low and high frequencies. H=-0.5 corresponds to white noise. Larger values make low frequencies dominant, while smaller values make high frequencies dominate. The parameter C1 controls the strength of rare extreme "bursts" in the field, with larger values causing more extreme values. The parameter α controls the probability of large negative spikes.
