Loudness |
This node takes a array of audio data and calculate loudness of that segment in decibel.
Loudness Calculation
Loudness is calculated using the following formula:
$$L = 10 \cdot \log_{10}\left(\frac{1}{N} \sum_{n=0}^{N-1} a[n]^2\right)$$
Where:
- L is the loudness in decibel
- N is the number of samples
- a[n] is the audio data
