Sergei N Gramnitskiy is a notable inventor based in Saint-Petersburg, Russia. He has made significant contributions to the field of audio processing, holding a total of 3 patents. His work focuses on methods that enhance the quality and usability of audio streams.

Latest Patents

One of his latest patents is a method of segmenting an audio stream. This innovative approach divides an input audio stream into segments that contain different homogeneous signals. The primary objective of this method is to localize segments with stationary properties. It identifies all non-stationary points or intervals in the audio stream and creates a list of segments. This list can be utilized for subsequent procedures, such as classification and attribution of speech, music, or noise. The segmentation method is based on analyzing the variation of audio signal statistical features and consists of three main stages: first-grade characteristics calculation, second-grade characteristics calculation, and decision-making.

Another significant patent by Gramnitskiy is a method of filtering noise from source digital data. This method involves filtering digital audio data with a short delay. The process includes buffering input source digital audio data, calculating the filtered digital data from the buffered input, and outputting a portion of the filtered data. The steps include calculating a correlation matrix, decomposing it, and calculating a filter matrix to approximate the filtered digital data.
