New updated - "Sound Lissajous Meter" ver 2.1

"Sound Lissajous Meter" has been updated to ver 2.1 now!

"Sound Lissajous Meter" is an app that displays the audio signal as a Lissajous curve in real time.

Lissajous is a plane figure obtained by combining two single vibrations that vibrate at right angles to each other.

With the microphone input signal on the vertical axis and the reference sine wave on the horizontal axis, it can be displayed as a two-dimensional curve with lissajous.



For example, you can play a sine wave of the same frequency as a reference sine wave signal from an audio system and observe its frequency and phase changes in the pattern of a Lissajous curve. If there is a lot of noise, a noise filter can be applied to make the display clearer.

　

In the case of unknown sound sources, the interrelationship of amplitude, frequency, and phase with the reference sine wave signal will help in the analysis of that source.

Recommended to check your own hearing ability on a daily basis for the audiophile, music players, sound professionals and all music lovers. Try to check if you have the golden ears!

It measures the minimum sound for each frequency that you can hear, and displays the measurement results as a graph. It can measure a wide range of frequencies from 30Hz to 20000Hz.



This measurement result can be displayed in two types of graphs: wideband frequency characteristics (LVL) and frequency characteristics with Absolute Threshold of Hearing (ATH). This measurement result can be saved as an image file.

# ATH frequency response of hearing (like Audiogram chart) .

　　

# LVL frequency response of hearing - Linear level without ATH compensation.

Giant lantern on Teramachi Kyogoku in Kyoto.

The giant lantern on Teramachi Kyogoku shopping street!

It is 2.65 meters long and 2.4 meters wide. It is located next to Mishima-tei, a famous sukiyaki restaurant.

I found it last night when I was walking along the Teramachi Kyogoku shopping street. It seems to have gone up at the end of last year. I didn't notice it until now because I don't often walk around here after dark.



This giant lantern was made by Kojima Shoten, a long-established Kyoto lantern maker. The making video is available on Youtube.

New updated - "Listening Tuner" ver 3.1

"Listening Tuner" was updated to ver 3.1 today.

"Listening Tuner" is a new sound amplifier app to assist you better hearing with equalizing many different frequency spectrum sound.

This app can easily adjust sounds to obtain your optimal hearing experience by using your iPhone mic and headphones. Also you can be a simulated experience of hearing loss.

It helps you to listen comfortable by using our proprietary digital processing technology, Graphic Parametric Equalizer, Preset Equalizer, Noise Suppressor and more sound control functions.



The Preset Equalizer has pre-registered equalizer settings that assume the hearing model.

EQ1: Voice Zoom
EQ2: Focus on vocals
EQ3: High frequency hearing loss compensation
EQ4: Low frequency hearing loss compensation

The Compressor can compress the dynamic range of the sound into three levels. Smaller sounds become louder, and louder sounds remain unchanged, making smaller sounds relatively easier to hear.



In this app, we do not collect any personal information.

Kamogawa in Kyoto

Before COVID-19, many people used to come to the riverside of Kamogawa river even in the middle of winter. But now, only few people come. I just hope that COVID-19 can be eradicated as soon as possible.
