Advanced Usage¤
The classify core plugin provides different functionality to analyze and extract features from your nendo library. Concretely the following features will be extracted:
| Feature | Description |
|---|---|
loudness |
This algorithm computes the loudness of an audio signal defined by Steven's power law. It computes loudness as the energy of the signal raised to the power of 0.67. |
duration |
The tracks duration in seconds. |
key |
The key of the track. |
scale |
The scale of the track. |
strength |
The strength of the estimated key. |
tempo |
The tempo of the track in BPM. |
avg_volume |
The average volume of the track. |
frequency |
This algorithm estimates the fundamental frequency given the spectrum of a monophonic music signal. |
intensity |
This algorithm computes the energy of an array. |
For more details also refer to the essentia documentation on which most of the feature extraction is based on.
