Title: Syavosh Zad-Issa: Innovator in Audio Signal Processing
Introduction
Syavosh Zad-Issa is a prominent inventor based in Irvine, CA, known for his contributions to audio signal processing. He holds 2 patents that showcase his innovative techniques in noise suppression and audio coding.
Latest Patents
One of his latest patents is focused on single-microphone wind noise suppression. This technique aims to suppress non-stationary noise, such as wind noise, in an audio signal. The method involves analyzing a series of frames of the audio signal to detect the presence of non-stationary noise. If such noise is detected, specific steps are taken to determine whether the frame contains only non-stationary noise or a combination of speech and non-stationary noise. Depending on the analysis, either a first filter or a second filter is applied to the frame to enhance audio clarity.
Another significant patent by Zad-Issa is related to a sub-band codec with native voice activity detection. This system provides an augmented version of a Low-Complexity Sub-band Coder (LC-SBC). The method involves receiving a series of input audio samples and generating sub-band samples for various frequency sub-bands. The system determines whether the frame is a voice frame or a noise frame. If it is identified as a noise frame, an index of previously processed sub-band samples is encoded instead of the current samples, optimizing the audio processing.
