dcblock~
A one-pole high-pass filter to remove DC components
Description
dcblock~ uses the following difference equation to remove DC components:
y[n] = x[n] - x[n - 1] + 0.9997 * y[n - 1]
This equation keeps the signal's average amplitude at zero, removing any DC offsets that might shift the average away from zero.
Arguments
gain [auto]
Optional
Changes the gain level.
Inlets
x [auto]
The signal to be filtered.
gain [auto]

reset [bang] (default: 0)
Banging this attribute will reset the object to its default state.
x [auto]
The signal to be filtered.
