Audification

A sonification technique that directly translates a data series into sound by mapping data values to audio waveform amplitudes, effectively "playing" the data as an audio signal. Unlike parameter mapping sonification, which maps data attributes to sound properties like pitch or volume, audification uses the data itself as the sound waveform. This produces a direct and unmediated auditory representation that can reveal patterns, periodicities, and anomalies in datasets. Audification is particularly useful for time-series data and has been applied in fields such as seismology (listening to earthquake data) and accessibility (providing non-visual access to scientific datasets).
