Product Development: PD7 - Modern Digital Processing of Microphone Signals

Paul Beckmann, DSP Concepts, LLC - Sunnyvale, CA, USA

Microphones have been in use for decades in professional audio applications. Recently they are also being incorporated into consumer and automotive products and their use is exploding. And although they are ubiquitous they are usually the weakest link in the audio signal chain. Common problems include dynamic range issues (too loud or too soft) and noise (electrical noise, background noise, wind, and plosives and sybillants). This session covers modern digital approaches to microphone processing. We use an interactive approach and build up the signal chain using graphical tools. We design single and multiband automatic gain controls, noise gates, and dynamics processors for reducing plosives and handling noise (“de-poppers”). We show how these algorithms are designed and tuned in practice.
