Band-Pass

Three-in-one filter that lets only certain frequencies through. Pick LowPass to remove frequencies above a chosen cut-off (cuts highs while keeping lows), HighPass to remove frequencies below it (cuts lows while keeping highs), or Notch to silently remove a narrow band around the cut-off. Useful for cleaning up rumble, hiss, or specific resonances without affecting the rest of the signal.

Band-Pass - Settings

Settings

Settings — filter mode, cut-off frequency, and bandwidth.

Property	Description
`Band-Pass Mode`	Filter mode. [default=HighPass]. `LowPass` removes frequencies above `CutOffFrequency`. `HighPass` removes frequencies below it. `Notch` removes a narrow band right at the cut-off and lets everything else through.
`Cut-off Frequency (Hz)`	Cut-off frequency, in Hz. [min=20, max=20000, default=100]. The frequency the filter pivots around. For `LowPass` and `HighPass` it's the point where the filter starts attenuating; for `Notch` it's the centre of the removed band.
`Q (1-10)`	Bandwidth (Q) of the filter. [min=1, max=10, default=1]. Controls how steeply the filter cuts. Low values produce a gentle slope; high values produce a sharp, narrow cut — particularly useful in `Notch` mode for removing a specific resonance without affecting nearby frequencies.
