Class Can be OneShot, or Loop for for repetitive sounds.
See also Classes for more information.
Categories
Categories One or more matching categories for the sound.
Note that if more than one category is present, secondary categories will appear slightly dimmed.
Categories
Length The total duration (playing time) of the sound.
The value is expressed as minutes:seconds:milliseconds
File Info
Samplerate The samplerate of the sound, e.g. 44100 for CD-quality audio. File Info
Channels Number of audio channels in the source file. File Info
Bits The bit-depth of the source file, e.g. 16 or 8-bit . File Info
Peak The peak amplitude in the sound, expressed as decibel (dB). -
RMS The average amplitude (RMS) expressed in decibel (dB). RMS/Loudness
Pitch The percieved pitch expressed as a note value.
Base frequency is 440 Hz, with +/- denoting detuning.
Note/Frequency
Pitch-conf. The 'pitch confidence'
A low value indicates that precise pitch measurement was not possible.
-
BPM The detected BPM (beats-per-minute) of the sound.
The tempo is not necessarily available for all sounds.
BPM/Tempo
BPM-conf. The 'tempo confidence'
a low value indicates that the tempo was found to be unstable.
-
Brightness The perceived 'brightness' of the sound
A value of 100 is very bright, while 0 is the opposite - a 'dark' or 'dull' sound.
Brightness
Harmonicity The perceived 'harmonicity' of the sound
This is a measurement of the distribution of harmonic partials, with 100 being a perfect distribution and 0 considered a very dissonant sound. Note that this is not an indication of whether a sound should be considered 'tonal' or not - aiming for a low 'noisiness' is often a better approach here.
Harmonicity
Noisiness The perceived 'noisiness' of the sound
This value indicates how 'noisy' the sound appears to be, with 100 being very noisy, and a value of 0 being the opposite. Or in other words, if your sound has a low noisiness, it's probably closer to a sine wave than white-noise.
