Setting Sound in Motion-Final Proposal

Abstract

The Leslie speaker although mechanically simple produces an output that is layered both in amplitude and in frequency. With separate drivers and mechanical elements for both high and low bands, this speaker produced two effects at once, tremolo and vibrato. The technical literature reviewed for this paper revealed that while both modulations can be achieved digitally in different ways, having them being done in parallel to separate frequency bands should be the final outcome. This paper will eventually point the reader in that direction with a proposal for an alternate emulation model. What this model will also attempt to achieve is the addition of an element of inertia into the speeding up and slowing down of the modulation rates.
