请求参数

Query 参数

ids

必需

A comma-separated list of the Spotify IDs for the tracks. Maximum: 100 IDs.

Header 参数

Authorization

必需

A valid access token from the Spotify Accounts service: see the Web API Authorization Guide for details.

返回响应

🟢200On success, the HTTP status code in the response header is `200 OK` and the response body contains an object whose key is `"audio_features"` and whose value is an array of audio features objects in JSON format. Objects are returned in the order requested

application/json

Body

audio_features

array[object (AudioFeaturesObject) {18}]

可选

acousticness

number

可选

A confidence measure from 0.0 to 1.0 of whether the track is acoustic. 1.0 represents high confidence the track is acoustic.

analysis_url

string

可选

An HTTP URL to access the full audio analysis of this track. An access token is required to access this data.

danceability

number

可选

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.

duration_ms

integer <int32>

可选

The duration of the track in milliseconds.

energy

number

可选

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.

string

可选

The Spotify ID for the track.

instrumentalness

number

可选

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.

key

integer <int32>

可选

The key the track is in. Integers map to pitches using standard Pitch Class notation . E.g. 0 = C, 1 = C♯/D♭, 2 = D, and so on.

liveness

number

可选

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.

loudness

number

可选

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 typical range between -60 and 0 db.

mode

integer <int32>

可选

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.

speechiness

number

可选

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.

tempo

number

可选

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.

time_signature

integer <int32>

可选

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).

track_href

string

可选

A link to the Web API endpoint providing full details of the track.

type

string

可选

The object type: "audio_features"

uri

string

可选

The Spotify URI for the track.

valence

number

可选

A measure from 0.0 to 1.0 describing the musical positiveness conveyed by a track. Tracks with high valence sound more positive (e.g. happy, cheerful, euphoric), while tracks with low valence sound more negative (e.g. sad, depressed, angry).
