P14345: Hybrid Audio Dynamics Processor

Project Summary Project Information

The Hybrid Audio Processor is device that allows audio professionals to control the amplitude profile of various source audio signals, most notably audio sources used in Motion Picture Pre-Show. An amplitude profile influences the way humans perceive sound. We often use words like ‘punchy’, ‘loud’, or ‘full’ when describing the amplitude profile. Being able to control the amplitude profile is very useful. It allows for the user to create interesting, dynamic sounds that please listeners, as well as provide protection for down stream devices.

Current dynamics processors on the market are high cost and lack some flexibility. This device would allow for advanced control while maintaining ultimate high audio fidelity. It would also be intuitive with familiar, industry standard controls. The device would also have user savable settings as well as try to achieve a lower cost than comparable units. Current professional units have a variety of design trade-offs that do not provide the optimal user experience that is described above.

The goal of this project is identify the needs of Motion Picture Pre-Show industry and develop a product that fit’s their needs, while maintaining the familiar attributes of common dynamics processors.

Acknowledgements

This project would not have been possible without the technical guidance of Les Moore, Mark Indovina, and Dorin Patru.

Also, a special thanks to Gene Goff, Dan Szaba, and Joey White of Ashly Audio for their technical guidance throughout this project. They provided helpful technical advice and valuable information that helped to shape our design.
