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 Samples is 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:
