Welcome to the Highcharts JS (highcharts) Options Reference

sonification.defaultInstrumentOptions.activeWhen

Define a condition for when a track should be active and not.

Can either be a function callback or a configuration object.

If a function is used, it should return a boolean for whether or not the track should be active. The function is called for each audio event, and receives a parameter object with time, and potentially point and value properties depending on the track. point is available if the audio event is related to a data point. value is available if the track is used as a context track, and valueInterval is used.
