METHOD FOR INHARMONIC TONE GENERATION USING A COUPLED MODE DIGITAL FILTER |
摘要 |
A coupled mode digital filter which simulates any number of arbitrarily tuned modes coupled together so as to share the same loss element at a junction loaded by an arbitrary impedance function is formed from the combination of one first order allpass filter [28] and one unit delay [30] per mode and one shared coupling filter[36]. This coupled mode digital filter may be excited by a stored or generated excitation signal, or a filtered excitation signal, to produce inharmonic percussive sounds and musically interesting two-stage and beating decay envelopes resulting from natural coupling of modes of near frequencies |
