Abstract
A system and method of logging audio signal data implement a data buffer and a non-volatile data storage medium. Acquired audio data may be stored in the buffer temporarily, for example, until a threshold amount or volume of data has accumulated in the buffer. Buffered audio and other data may be written to the nonvolatile storage medium in large blocks, minimizing the number of write operations to the non-volatile storage medium. System or process diagnostics may be performed based upon analysis of the acquired audio signal data. Additionally, monitored audio signal data may be employed for real-time process or system control.
