Abstract
A method dynamically allocating voices to processor resources in a music synthesizer or other audio processor includes utilizing processor resources to execute vector-based voice generation algorithm for sounding voices, such as executed using SIMD architecture processors or other vector processor architectures. The dynamic voice allocation process identifies a new voice to be executed in response to an event. The combined processor resources needed to be allocated for the new voice and for the currently sounding voices are determined. If the processor resources are available to meet the combined need, then processor resources are allocated to a voice generation algorithm for the new voice, and if the processor resources are not available, then voices are stolen. To steal voices, processor resources are de-allocated from at least one sounding voice or sounding voice cluster.
