Properties

confidence ↔ double?

The confidence, from 0.0 to 1.0, of the reliability of the segmentation. Segments of the song which are difficult to logically segment (e.g: noise) may correspond to low values in this field.

getter/setter pair

duration ↔ double?

The duration (in seconds) of the segment.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

loudnessEnd ↔ double?

The offset loudness of the segment in decibels (dB). This value should be equivalent to the loudnessStart of the following segment.

getter/setter pair

loudnessMax ↔ double?

The peak loudness of the segment in decibels (dB). Combined with loudness_start and loudness_max_time, these components can be used to describe the “attack” of the segment.

getter/setter pair

loudnessMaxTime ↔ double?

The segment-relative offset of the segment peak loudness in seconds. Combined with loudnessStart and loudnessMax, these components can be used to describe the “attack” of the segment.

getter/setter pair

loudnessStart ↔ double?

The onset loudness of the segment in decibels (dB). Combined with loudnessMax and loudnessMaxTime, these components can be used to describe the “attack” of the segment.

getter/setter pair

pitches ↔ List<double>?

A “chroma” vector representing the pitch content of the segment, corresponding to the 12 pitch classes C, C#, D to B, with values ranging from 0 to 1 that describe the relative dominance of every pitch in the chromatic scale.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

start ↔ double?

The starting point (in seconds) of the segment.

getter/setter pair

timbre ↔ List<double>?

Timbre is the quality of a musical note or sound that distinguishes different types of musical instruments, or voices. Timbre vectors are best used in comparison with each other.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
