Introducing dåpf, the first dedicated effects processor in the Instruo product line.
The Instruo 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
