Latest Patents

Among his latest patents, Joon Il Lee has developed a method and apparatus for processing an audio signal. This invention involves obtaining a stereophonic audio signal that includes a speech component and other component signals. The process includes determining gain values for each channel of the audio signal and identifying whether the audio signal is an inverse-phase mono signal. If it is, the phase of the gain value for one channel is inverted, modifying the speech component signal accordingly. This results in a modified audio signal that is an in-phase mono signal. Another notable patent focuses on controlling the volume of an audio signal using a non-linear gain curve and reference information. This invention allows for adaptive volume control based on metadata and environmental characteristics.
