Abstract: An audio phase corrector circuit which shifts the phase of substantially all frequencies of an audio signal by 90 degrees for the purpose of enhancing sound produced by an electroacoustic transducer. Embodiments are implemented by a digital finite impulse response filter configured to operate as a 90-degree phase shift circuit, commonly called a Hilbert transformer. The 90-degree phase shift corrects a characteristic phase distortion caused by electroacoustic transducers and thereby retains much of the impulse and transient information in the acoustic output that would otherwise be lost. The resulting sound has substantially improved clarity, detail, presence, placement, and spaciousness.
