  Restructuring Ittiam`s Acoustic clarity solution (ACS)The entire ACS codebase was made modular. Making the code readable and standardized for faster development and verification.• To make MATLAB implementation in line with fixed point implementation. Have a modular approach in MATLAB as well. Verify the closeness of MATLAB and fixed-point output. • Code clean up, reduce memory footprint and introduce exception handling.• Modularization of the software product making it flexible to plug and play for any module.Customer Support and Demos• Ported ACS into Cortex-M4 based CPU to demonstrate the solution for low power applications. Complexity reduction and making cross platform changes was a key challenge.• Worked on integrating ACS on Linux and Android platforms.• Working with top tier customers providing integration support for Ittiam`s ACS.• Arranging demos to the customers as well in major tech exhibitions.• Handling the bug reports and ensuring the library maintenance for the existing customers.• Demoed BAT-VISION in Ittiam’s Tech Fest, where a PTZ camera was directed towards the active source based on Sound source localization.Tuning Acoustic Echo Cancellation and Residual Echo Suppression for specific market devicesThe performance of AEC changes from device to device and the target situation. Given a situation,It is important to get the right parameters for optimal performance.• Understand the implementation aspects of sub modules in detail.• To analyze the device characteristics with respect like coupling behavior, distortion and mic positioning and use these to tune the ACS.• Improve the control logic to make it more effective on the target device.• Understand the audio pipeline in android and its behavior to solve some system level issues.
