InstrumentActivityResult

struct · iOS 27.0+ · SDK 27.1

struct InstrumentActivityResult

A structure containing the activity levels and detected time ranges for instruments in a song. The ``activity`` property provides a continuous signal for each instrument. The values range from `0.0`, not present to `1.0`, fully active. The ``ranges`` property provides discrete time windows during which the framework detected each instrument. Use both properties together to determine when an instrument is present and how prominently it features at each moment.
