Hichigiri, special wagashi for Hinamaturi festival

Today, March 3 is an ancient Japanese festival, Hinamaturi festival.　

I ate a special Kyoto wagashi for this festival called Hichigiri!

It is a simple and mysterious shaped wagashi that has been around for over 1,200 years since the Heian period.

It is made by famous wagashi confectionery, "Oimatsu" in Nishijin, the bottom rice cake is Konashi (the green one is filled with tansy), and the top is Kinton.

The sweetness was a little subdued, and the fragrance of the tansy was so refreshing that it made me feel that spring was near. The cold winter in Kyoto seems to be finally over.

New updated iOS app - "Sound Lissajous Meter" ver 3.0

"Sound Lissajous Meter" has been updated to version 3.0 today!

"Sound Lissajous Meter" is an iPhone app that can display audio signals as Lissajous curves in real time.

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

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



For example, a sine wave of the same frequency as the reference sine wave can be played back from an audio system and its frequency and phase changes can be observed in the Lissajous curve pattern. If there is a lot of noise, it can be displayed more clearly by applying a filter.



In the case of an unknown sound source, the interrelationship of amplitude, frequency, and phase with a reference sine wave can be used to analyze the source.

New updated iOS app - "High-Frequency Noise Monitor" ver 3.0

"High-Frequency Noise Monitor" has been updated to version 3.0 now!

"High-Frequency Noise Monitor" is a high-frequency noise analysis tool that specializes in high-frequency bands above 8 kHz.

You may be exposed to artificial high-frequency noise on a daily basis that is inaudible to the human ear. This app allows you to monitor such high frequency noises and examine their occurrence.

In general, noise may contain relatively high frequency components depending on its source, and this is classified as high frequency noise.

For example, harmonic noise is radiated from the main body of an electronic device or the power lines of a power conversion device such as a AC-DC power adapter, and depending on its power level, it may affect peripheral devices.

There are also devices that generate high-frequency noise to drive away vermin such as rats and weasels. The frequency of the sound varies depending on the type of vermin, and some devices incorporate sensors to change the volume and frequency over time. When such devices are installed in the vicinity, there are cases where they can lead to noise problems with adverse effects on human health.

High-frequency noise does not often occur at a constant volume or frequency, but often occurs in a certain cycle or randomly. It is not easy to detect such high-frequency noise.

This app records randomly fluctuating high-frequency noise from the iPhone built-in microphone and performs frequency analysis in real time.

The latest version has an updated UI design and improved application stability.



In addition, it retains the PCM data for 20 seconds just before the measurement is stopped, and displays a spectrogram by FFT or the octave band analysis.

The spectrogram is a graph showing the analysis results of the frequency spectrum of sound with time on the vertical axis, frequency on the horizontal axis, and signal strength in colors, allowing visual observation of the occurrence of high-frequency noise.
