Methods for real time harmonic excitation of acoustic signals
<29> This paper presents a comparison of methods for introducing harmonic partials to signals in real-time. The algorithms are assessed on how accurately they can approximate the desired harmonics, through use of psycho-acoustically derived metrics and subjective listening tests. The work is intended to aid in the field of audio processing, allowing for fine control over spectral content while preserving harmonicity. This can be used in systems that provide computer-based music producers with the capability to have predictable (through the use of semantics such as brightness, warmth, etc.) perceptual control of timbre over a wider range of signals than current systems.
