Struct LoudnessDesc

pub struct LoudnessDesc {
    pub values: Vec<f32>,
}

Loudness (in dB) detection object.

It indicates how “loud” a recording of a song is. For a given audio signal, this value increases if the amplitude of the signal, and nothing else, is increased.

Of course, this makes this result dependent of the recording, meaning the same song would yield different loudness on different recordings. Which is exactly what we want, given that this is not a music theory project, but one that aims at giving the best real-life results.

Ranges between -90 dB (~silence) and 0 dB.

(This is technically the sound pressure level of the track, but loudness is way more visual)
