Properties

analysisChannels ↔ int?
getter/setter pair
analysisSampleRate ↔ int?
The sample rate used to decode and analyze this track.
getter/setter pair
codeString ↔ String?
An Echo Nest Musical Fingerprint (ENMFP) codestring for this track.
getter/setter pair
codeVersion ↔ double?
A version number for the Echo Nest Musical Fingerprint format used in the codeString field.
getter/setter pair
confidence ↔ double?
The confidence, from 0.0 to 1.0, of the reliability of the section’s “designation”.
getter/setter pairinherited
duration ↔ double?
The duration (in seconds) of the section.
getter/setter pairinherited
endOfFadeIn ↔ double?
The time, in seconds, at which the track's fade-in period ends. If the track has no fade-in, this will be 0.0.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
key ↔ int?
The estimated overall key of the section. The values in this field ranging from 0 to 11mapping to pitches using standard Pitch Class notation (E.g.0 = C, 1 = C♯/D♭, 2 = D, and so on). If no key was detected, the value is -1`.
getter/setter pairinherited
keyConfidence ↔ double?
The confidence, from 0.0 to 1.0, of the reliability of the key. Songs with many key changes may correspond to low values in this field.
getter/setter pairinherited
loudness ↔ double?
The overall loudness of the section in decibels (dB). Loudness values are useful for comparing relative loudness of sections within tracks.
getter/setter pairinherited
mode ↔ int?
Indicates the modality (major or minor) of a track, the type of scale from which its melodic content is derived. This field will contain a 0 for “minor”, a 1 for “major”, or a -1 for no result. Note that the major key (e.g. C major) could more likely be confused with the minor key at 3 semitones lower (e.g. A minor) as both keys carry the same pitches.
getter/setter pairinherited
modeConfidence ↔ double?
The confidence, from 0.0 to 1.0, of the reliability of the mode.
getter/setter pairinherited
numSamples ↔ int?
The exact number of audio samples analyzed from this track. See also analysisSampleRate.
getter/setter pair
rhythmString ↔ String?
A Rhythmstring for this track. The format of this string is similar to the synchString.
getter/setter pair
rhythmVersion ↔ double?
A version number for the Rhythmstring used in the rhythmString field.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
startOfFadeOut ↔ double?
getter/setter pair
synchString ↔ String?
getter/setter pair
synchVersion ↔ double?
A version number for the Synchstring used in the synchstring field.
getter/setter pair
tempo ↔ double?
The overall estimated tempo of the section in beats per minute (BPM). In musical terminology, tempo is the speed or pace of a given piece and derives directly from the average beat duration.
getter/setter pairinherited
tempoConfidence ↔ double?
The confidence, from 0.0 to 1.0, of the reliability of the tempo. Some tracks contain tempo changes or sounds which don’t contain tempo (like pure speech) which would correspond to a low value in this field.
getter/setter pairinherited
timeSignature ↔ int?
An estimated overall time signature of a track. The time signature (meter) is a notational convention to specify how many beats are in each bar (or measure). The time signature ranges from 3 to 7 indicating time signatures of “3/4”, to “7/4”.
getter/setter pairinherited
timeSignatureConfidence ↔ double?
The confidence, from 0.0 to 1.0, of the reliability of the timeSignature. Sections with time signature changes may correspond to low values in this field.
getter/setter pairinherited
