Subsample configuration: similarity

The 5 settings under similarity, each with the type, default and limits its schema declares.

How much each group of acoustic measurements counts when Subsample compares a sample with a reference. 0 leaves a group out of the comparison.

weight_spectral in similarity

Type
number
Default
1
Limits
at least 0, at most 2

Weight of the spectral shape group: brightness, noisiness, attack and release time, and similar measures of a sound's overall character.

weight_timbre in similarity

Type
number
Default
1
Limits
at least 0, at most 2

Weight of the sustained timbre group, averaged over the whole sound. Raise it to tell instrument families apart in a library of sustained tonal sounds.

weight_timbre_delta in similarity

Type
number
Default
0.5
Limits
at least 0, at most 2

Weight of the timbre change group, which follows how the timbre moves over the sound, such as the shift from attack to sustain in a plucked string.

weight_timbre_onset in similarity

Type
number
Default
1
Limits
at least 0, at most 2

Weight of the attack timbre group, measured over the start of the sound. Raise it for percussion, where kick, snare, and hi-hat differ most in their attacks.

weight_band_energy in similarity

Type
number
Default
1
Limits
at least 0, at most 2

Weight of the spectral band energy group: how a sound's energy and decay divide between the bass, low-mid, high-mid, and high spectral bands. Raise it for drum libraries, and lower it for pitched instruments.
