introducing dåpf, the first dedicated effects processor in the instruō product line. the instruō dåpf is a set of two analogue all-pass filters.
you might be asking yourself, "what is the point of a filter that passes everything?" all-pass filters don't actually attenuate frequency amplitudes directly but rather alter the phase relationship of frequencies across the spectrum. all-pass filter stages appear
in the vast majority of voltage-controlled filter topologies as well as serving as a core building block within dsp.
the normalled i/o of dåpf allows for cascaded or independent use of the two all-pass filter circuits, offering everything from classic phase-shifting to psychoacoustic stereo enhancement and synthetic doppler effect.
features:
two parallel all-pass filters
independent attenuverters for voltage control
1-pole/2-pole configuration for left channel
cascaded normalisation
global 1 volt per octave tracking
