spotifywebapipython.models.audiofeatures
Spotify Web API AudioFeatures object.
Initializes a new instance of the class.
Arguments:
- root (dict): Spotify Web API JSON response in dictionary format, used to load object attributes; otherwise, None to not load attributes.
A confidence measure from 0.0 to 1.0 of whether the track is acoustic.
1.0 represents high confidence the track is acoustic.
Example: 0.00242
A URL to access the full audio analysis of this track.
An access token is required to access this data.

Danceability describes how suitable a track is for dancing based on a combination of musical
elements including tempo, rhythm stability, beat strength, and overall regularity.
A value of 0.0 is least danceable and 1.0 is most danceable.
Example: 0.585
Energy is a measure from 0.0 to 1.0 and represents a perceptual measure of intensity and activity.
Typically, energetic tracks feel fast, loud, and noisy. For example, death metal has high energy,
while a Bach prelude scores low on the scale. Perceptual features contributing to this attribute
include dynamic range, perceived loudness, timbre, onset rate, and general entropy.
Example: 0.842
Predicts whether a track contains no vocals.
"Ooh" and "aah" sounds are treated as instrumental in this context. Rap or spoken word
tracks are clearly "vocal". The closer the instrumentalness value is to 1.0, the greater
likelihood the track contains no vocal content. Values above 0.5 are intended to represent
instrumental tracks, but confidence is higher as the value approaches 1.0.
Example: 0.00686
The key the track is in.
Integers map to pitches using standard Pitch Class notation (e.g. 0 = C, 1 = C#, 2 = D, and so on). If no key was detected, the value is -1.
Range: -1 to 11
Example: 9
Detects the presence of an audience in the recording. Higher liveness values represent an increased probability that the track was performed live. A value above 0.8 provides strong likelihood that the track is live.
Example: 0.0866
The overall loudness of a track in decibels (dB).
Loudness values are averaged across the entire track and are useful for comparing relative loudness of tracks. Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude). Values typically range between -60 and 0 db.
Example: -5.883
Mode indicates the modality (major or minor) of a track, the type of scale from which its melodic content is derived. Major is represented by 1 and minor is 0.
Example: 0
Speechiness detects the presence of spoken words in a track. The more exclusively speech-like
the recording (e.g. talk show, audio book, poetry), the closer to 1.0 the attribute value.
Values above 0.66 describe tracks that are probably made entirely of spoken words.
Values between 0.33 and 0.66 describe tracks that may contain both music and speech, either
in sections or layered, including such cases as rap music. Values below 0.33 most likely
represent music and other non-speech-like tracks.
Example: 0.0556
The overall estimated tempo of a track 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.
Example: 118.211
An estimated time signature.
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".
Range: 3 to 7
Example: 4
A link to the Web API endpoint providing full details of the track.
