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 - "Wavelet Voice Sonogram" ver 3.0

"Wavelet Voice Sonogram" has been updated to version 3.0 today!

"Wavelet Voice Sonogram" is an iPhone app that performs acoustic analysis of voice signals and displays a spectrogram.

A spectrogram is a graph showing the results of sound frequency spectrum analysis with time on the horizontal axis, frequency on the vertical axis, and signal strength represented by colors, and is used for voice analysis, voiceprint identification, and other purposes.

The application can perform acoustic analysis and display spectrograms using three time-frequency analysis techniques: Wavelet analysis, Octave-band analysis and FFT analysis.

It is easy to perform acoustic analysis of speech, instrumental sounds, noise, and so on. It can also be used for elementary learning of speech analysis.

In this latest version, the UI design has been updated and the stability of the application has been improved.

- Wavelet analysis


- Octave-band analysis


- FFT analysis


It is possible to record audio signals from the iPhone's built-in microphone. While playing back sound, you can search for the desired sound and perform acoustic analysis.

　　　

The zoom function allows you to zoom in on a specific period of approximately 10 seconds of PCM data to find the point you want to analyze.
