What is a Dynamics Processor? A dynamics processor allows users to alter the dynamics of a source signal. A compressor, a type of dynamics processor, will make loud sounds soft and soft sounds loud.

Problem Statement 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 downstream devices.

Problem Statement 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.

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

Deliverables a functioning prototype simulation results verifying proper functionality documentation with board schematics and board artwork source code and libraries used

Use Scenarios Manual Mode - This mode of operation will allow for user to manually manipulate the the threshold, ratio, attack and release settings for maximum control.

Use Scenarios Automatic Mode - The goal of this mode is to provide automatic gain leveling with minimal interaction from the user.
