Channel Divider

A specialized tool that splits your stereo signal into separate frequency bands and routes each band to a different stereo output pair. It is useful for multi-amplifier, multi-speaker, or custom crossover playback setups.

To use this effect, you need to use the desktop app, set the number of output channels in the audio settings to 4, 6, or 8 depending on the number of bands, and set the channel in the effect bus routing to “All.”

When to Use

  • When using multi-channel audio outputs (4, 6, or 8 channels)
  • To create custom frequency-based channel routing
  • For multi-amplifier or multi-speaker setups

Parameters

  • Band Count - Number of frequency bands to create (2-4 bands)
    • 2 bands: Low/High split, requiring 4 output channels
    • 3 bands: Low/Mid/High split, requiring 6 output channels
    • 4 bands: Low/Mid-Low/Mid-High/High split, requiring 8 output channels
    • Higher band counts are unavailable when the selected output channel count is too low
  • Crossover Frequencies - Define where audio splits between bands
    • F1: First crossover point
    • F2: Second crossover point (for 3+ bands)
    • F3: Third crossover point (for 4 bands)
    • Each crossover can be set from 10 Hz to 40000 Hz
    • The plugin keeps F1, F2, and F3 in ascending order with at least 1 Hz separation
  • Slopes - Control how sharply bands are separated
    • Options: -12dB to -96dB per octave
    • Steeper slopes provide cleaner separation
    • Lower slopes offer more natural transitions

Technical Notes

  • Processes first two input channels only
  • Output channels must be a multiple of 2 (4, 6, or 8)
  • Each band keeps the original stereo pair: 2-band mode outputs Low to channels 1-2 and High to channels 3-4; 3-band mode uses channels 1-2, 3-4, and 5-6; 4-band mode uses channels 1-2, 3-4, 5-6, and 7-8
  • Uses high-quality Linkwitz-Riley crossover filters
  • Visual frequency response graph for easy configuration
