LoudnessResult
A structure that contains perceptual loudness measurements for a song, including integrated, momentary, short-term, and peak values.
Declaration
struct LoudnessResultOverview
The LoudnessResult delivers perceptual loudness measurements that align with human hearing perception, using the Loudness K-weighted Full Scale (LUFS) standard defined in ITU-R BS.1770.
The results contain time-based measurements, including integrated loudness, short-term loudness, momentary loudness, and peak amplitude.
When used in SessionResult, a single LoudnessResult contains all analysis values for the entire song, with momentary and shortTerm arrays containing the complete set of measurements across the song’s duration.
When used in the streaming loudnessResults context, the framework delivers multiple results progressively during analysis. Each result’s momentary and shortTerm arrays contain only one value representing the measurement at that point in time.
