He has made significant contributions to the field of acoustic echo control, holding 2 patents that showcase his innovative approach to solving complex audio challenges. His work is particularly relevant in communication technologies, where clarity and quality of sound are paramount.
Latest Patents
One of Babin's latest patents is focused on time-domain acoustic echo control. In this invention, an acoustic echo control (AEC) module receives both outgoing and incoming signals, which may contain acoustic echoes. The AEC module utilizes a delay estimation block to estimate the echo delay in the time domain through an adaptive filtering technique. This estimation aligns samples of the incoming signal with the corresponding outgoing signal, allowing the AEC module to determine the presence of acoustic echo. The module then suppresses the echo and adds comfort noise to enhance the incoming signal's quality.
Another notable patent involves an adaptive filter that employs multiple algorithm species, each differing in echo suppression quality and computational resource demands. This adaptive filter selects the most suitable algorithm based on the available computational budget, ensuring optimal echo suppression without overwhelming the host communication device's resources. The filter can also adjust its algorithm species as needed, maintaining high-quality performance.
