Title: Irwin H. Kornfeld: Innovator in Audio Technology
Introduction
Irwin H. Kornfeld is a notable inventor based in Brooklyn, NY, recognized for his contributions to audio technology. With a total of 3 patents, Kornfeld has made significant advancements in the field of stereo reproduction and time compression audio systems.
Latest Patents
Kornfeld's latest patents include innovative systems designed to enhance audio playback. One of his patents, titled "Stereo reproduction with gapless splicing of pitch altered waveforms," introduces a time compression audio reproduction system that operates two stereo channels. This system synchronously operates pitch correction means in each channel to achieve time coincidence between corresponding portions of the signal output. Key features of this invention include switching mechanisms for alternately selecting delay elements.
Another significant patent is "Gapless splicing of pitch altered waveforms." This invention provides a time compression/expansion system for recorded programs, allowing for time changes during playback while ensuring pitch correction is free of gaps or processing noise. The system utilizes a dual memory delay mechanism that inversely varies delay, enabling the detection of the next program sample's start with matched signal amplitude and sign. This continuous pitch correction enhances the listening experience by maintaining audio quality.
