Separates audio into multiple channels by frequency.
This node is useful for visualizing or processing audio based on ranges of pitches.
This node splits a single channel into a list of channels, each composed (mostly) of frequencies within a distinct range. (Since the splitting is done using audio filters with a gradual slope, some frequencies outside the range are present at lower amplitudes.)
Cutoff Frequencies— The borderlines between frequency ranges, in Hz. The number of items in
Split Samplesis one more than the number of items in
Split Samples— The split channels, in ascending order of frequency.
As an example, a list of 3 frequency cutoff values — 300, 1200, 4000 — will result in 4 output channels:
