Classifier Overview

The Cyanite API exposes a variety of classifiers for your music.

Genre

The genre multi-label classifier provides the following labels:

  • Ambient
  • Blues
  • Classical
  • Country
  • Electronic / Dance
  • Indie / Alternative
  • Jazz
  • Latin
  • Metal
  • Punk
  • Rap / Hip Hop
  • Reggae
  • Rock
  • Singer / Songwriter

Each label has a score reaching from 0-1, where 0 (0%) indicates that the track is unlikely to represent a given genre and 1 (100%) indicates a high probability that the track represents a given genre.

Since music could break genre borders the genre multi-label can predict multiple genres for a given song instead of only predicting one genre. A track could be classified with Rap / Hip Hop (Score: 0.9) but also Reggae (Score: 0.8).

The genre can be retrieved both for the whole track and the track segments.

Mood

The mood multi-label classifier provides the following labels:

  • Energetic
  • Uplifting
  • Happy
  • Relaxing
  • Calm
  • Melancholic
  • Dark
  • Tense

Each label has a score reaching from 0-1, where 0 (0%) indicates that the track is unlikely to represent a given genre and 1 (100%) indicates a high probability that the track represents a given genre.

Since music can be an emotional rollercoaster the mood multi-label can predict multiple moods for a given song instead of only predicting one mood. A track could be classified with Dark (Score: 0.9), while also being classified with Tense (Score: 0.8).

The mood can be retrieved both for the whole track and the track segments.

Energy Level

The Energy Level is a label for the intensity of an analysed track which can be either low, medium, high or variable. A low Energy Level indicates a calm overall appearance of a track while a high one stands for more strong and powerful characteristics. A track with a variable energy level will hold steady changes in its intensity profile.

Energy Dynamics

With Energy Dynamics, we label the progression of the Energy Level throughout the duration of the music piece, where a low Energy Dynamics label stands for a stable trend and a high one depicts a strong variance between low and high Energy Levels. Is the Energy Dynamic labeled as high it implies a variable Energy Level (s.o.).

Emotional Profile

The energy profile describes the tendency of a track expressing either a positive, neutral or negative emotion. Tracks with steady changes in their emotive expression will be labelled as variable.

Emotional Dynamics

With Emotional Dynamics, we label the progression of the Emotional Profile throughout the duration of the music piece, where a low Emotional Dynamics label stands for a stable trend and a high one depicts a strong variance between low and high Emotional Profiles. Is the Emotional Dynamic labeled as high it implies a variable Emotional Profile (s.o.).

Voice Mean

The Voice Mean Scores depict the portions of the track containing female or male singing voice or being instrumental (non-vocal).

Voice Presence Profile

This label describes the amount of singing voice throughout the full duration of the track and may be low, medium or high.

Predominant Voice Gender

This label indicates if the predominant singing voice holds more likely female or male characteristics. It may be none if no singing voice is detected.

BPM

The BPM classifier provides you the BPM of the track.

Key

The Key classifier provides you with a range of possible keys and the corresponding confidence.
