essentia-container

An alpine-based Essentia extractor docker container image.

Essentia extractors allow to extract low and high level musical information from audio data (e.g. average_loudness, bpm, danceability, electronic). Some of the extracted fields and detection accurracies are described here (for an older version, though).

Differences compared to the official pre-built binaries and container (as of 2023):

• The binaries are compiled with Gaia.
• Contains the SVM models and a corresponding example profile.
• Uses Alpine Linux base image instead of Debian.
• Multi-arch image that works on both amd64 and arm64 Linux machines.

Usage

The following example shows how to download an audio file, analyze it using essentia_streaming_extractor_music and print the result JSON:

docker run --rm ghcr.io/mgoltzsche/essentia sh -euxc '
  URL=https://www.learningcontainer.com/wp-content/uploads/2020/02/Kalimba.mp3
  wget -qO input.mp3 $URL
  essentia_streaming_extractor_music input.mp3 - /etc/essentia/profile.yaml'
