The Chart Visual View

Located at the top of the CHART VISUALS View are the 3 to 5 Audio Features Traktomizer regards as requiring the least amount of change for the greatest gain in chartability score. An example of this statement might be something like:

To maximise 'YourSongName' plays, streams, recommendations and auto-discovery focus on improving these weaker audio features first: Danceability, Acousticness, Duration.

Note that this statement excludes any social activity KPIs i.e. it is based only on Benchmark Audio Features Analysis taking no social media activity into account.

The statement is indicative only of your song's Audio Feature Vectors as they relate to Ideal Ranges and your Benchmark Analysis Pool's aggregated ranges of Audio Feature Vectors.


A chartability score lower than 50% would suggest that fairly significant changes should be made to your song (by you) before publishing it or sending it to your Mastering Engineer. Changes to audio properties which exhibit the most impact for the least amount of change are listed in descending order on the next two lines.

Scores over 50% suggest changes are relatively optional but taking a look at the weak audio properties is recommended.

Scoring over 70% reveals your song is in terrific shape and no further changes need to be made. Of course you are welcome to try and push the envelope.

A Chartability score greater than 60% suggests you may have a hit song on your hands.

Disclaimed: regardless of the chartability score rating reported by Traktomizer your song's actual chart (or non-charting) outcome is never a guarantee and as such all Traktomizer analysis and reporting is for informational purposes only.

Dashboard Gauges

  • Grand Total: a visualisation of your total score relative to the maximum achievable score

  • In Ideal Range: a visualisation of your in-range score relative to everything being in-range

  • Above Median: a visualisation of how much above average you scored

  • Artist Hotness: your Spotify Hotness' e.g. for a value of 0.5 you would see a half-filled dial

  • In Top Ranks: a visualisation of your standing relative to the maximum benchmarks' scores

  • In Top 3rd: a visualisation of your standing relative to median of the top 3 benchmark scores

  • Social Activity: a visualisation of how active you are in social media

  • In Top Genre: a visualisation of whether your song is in a top recommended genre

Audio Property Dials

Danceability, Acousticness, Valence, Duration, Energy, Loudness, Speechiness, All Audios.

Each of these dials is a visualisation of your songs' audio feature relative to the Benchmark Analysis Pool aggregate mean.

For detailed information about the meaning of each of these essential audio features as they relate to Music Information Retrieval (MIR) see Traktomizer Online Help. For even more detail about their meanings which is beyond the scope of these manuals please visit this page at Spotify.

Summary Charts View

In the middle of the Chart Visuals page are three bar-charts for visualising your songs most important audio feature vectors compared with your nominated benchmark songs' counterpart. The features shown include: Danceability, Acousticness, Instrumentalness, Valence, Duration, Energy, Liveness, Loudness, Speechiness, and Tempo.

The additional attributes described below may be scrutinised either by opening their detailed chart view or by looking at the audio features JSON file.

An Audio Feature is a computer-estimated subjective quality of a song or track. It is modelled through learning and is given as a single floating point number ranging from 0.0 to 1.0. Spotify derives the overal description of a song from the audio feature values that comprise it. Songs can be sorted by any of their axes and the attributes can be used as filters for constructing custom playlists.


Describes how suitable a track is for dancing using a number of musical elements (the more suitable for dancing, the closer to 1.0 the value). The combination of musical elements that best characterise danceability include tempo, rhythm stability, beat strength, and overall regularity.


Represents a perceptual measure of intensity and powerful activity released throughout the track. Typical 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.


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.


Detects the presence of an audience in the recording. The more confident that the track is live, the closer to 1.0 the attribute value. Due to the relatively small population of live tracks in the overall domain, the threshold for detecting liveness is higher than for speechiness. A value above 0.8 provides strong likelihood that the track is live. Values between 0.6 and 0.8 describe tracks that may or may not be live or contain simulated audience sounds at the beginning or end. Values below 0.6 most likely represent studio recordings.


Represents the likelihood a recording was created by solely acoustic means such as voice and acoustic instruments as opposed to electronically such as with synthesised, amplified or electrified instruments. Tracks with low acousticness include electric guitars, distortion, synthesizers, auto-tuned vocals, and drum machines; whereas songs with orchestral instruments, acoustic guitars, unaltered voice and natural drum kits will have acousticness values closer to 1.0.


Describes 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). This attribute in combination with energy is a strong indicator of acoustic mood, the general emotional qualities that may characterise the track's acoustics. Note that in the case of vocal music, lyrics may differ semantically from the perceived acoustic mood.

Time Signature

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 estimated overall key of a track. The key identifies the tonic triad, the chord - major or minor, which represents the final point of rest of a piece.


Indicates the modality (major or minor) of a track, the type of scale from which its melodic content is derived.


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.


The overall loudness of a track in decibels (dB). Loudness values are averaged across an entire track and are useful for comparing relative loudness of segments and tracks. Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude).


The duration of a track in seconds as precisely computed by the audio decoder.
