Title: Kaoru Izawa: Innovator in Audio Technology

Introduction

Kaoru Izawa is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of audio technology, particularly through his innovative patents. With a total of 2 patents, Izawa has demonstrated his expertise and creativity in developing advanced audio devices.

Latest Patents

Izawa's latest patents include an echo attaching circuit and an audio device utilizing the same technology. The first patent describes an analog signal that is delayed and compressed using a monotonously increasing, convex compression function. This signal is then sent to a delay circuit, which is digitally constituted. After a constant delay time, the digital value stored in memory is read out and converted back into an analog signal by a D/A converter. The analog signal is then expanded according to a reverse function of the compression function, effectively restoring it as an echo signal. The second patent also focuses on an echo attaching circuit and audio device, which includes a compression circuit for compressing either an audio signal or a mixture of the audio signal and an echo signal. This invention features a delay circuit that delays the output signal of the compression circuit by a predetermined time, along with an expansion circuit controlled by a DC voltage generated in response to the volume controller's regulation. This setup allows for the generation of the echo signal through a reverse conversion function.
