Sigma DSP for active speaker systems

This paper explores the process that can be used to create active speakers and initial (low cost) measurements using readily available PC-based tools. From the hardware perspective the Sigma DSP part is easy to design in to a system. Sigma Studio offers a powerful set of easy to use DSP features for creation of audio applications and is well suited to the needs of active speaker design. Combining a speaker prototype with the EVM, amplifiers, and PC based analysis tools some very quick desktop prototyping can be done with minimal expense before moving in to a test chamber with full instrumentation.
