New updated iOS app - "Wavelet Voice Sonogram" ver 4.0

icon-wvs_v200.png

"Wavelet Voice Sonogram" has been updated to version 4.0 now!

"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.

The latest version supports iOS 17 and improves stability and performance.

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.

New updated iOS app - "High-Frequency Noise Monitor" version 4.0

icon-hfnm_v300.png

"High-Frequency Noise Monitor" has been updated to version 4.0 today!

The latest version supports iOS 17 and improves stability and performance.

"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 AC-DC power adapter, and depending on its power level, it may affect peripheral devices.

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.

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.

I visited the "Blooming" lighting event at Heian Jingu Shrine in Kyoto.

Blooming20231007-1.JPG

It was a dedication event by JRA Kyoto Racecourse, so Daigoku-den Hall was lit up from Keitenmon Gate at the entrance to Heian Jingu Shrine.

The projection mapping of the Daigoku-den Hall was a fantastic scene of autumn cherry blossoms and chrysanthemums in full bloom and racehorses running at full gallop, inspired by the Shukka-sho and Kikka-sho, the G1 race.

This event is free of charge and will be held for 9 days from 10/6 to 10/14 (17:30-20:30).

icon-afa_v800.png

"Audio Frequency Analyzer" has been updated to version 9.0 today!

The latest version is compatible with iOS 17.0 and has improved internal processing and performance.

"Audio Frequency Analyzer" is a powerful Real-time Audio Analyzer (RTA) app for iPhone.

It uses our proprietary signal processing technology to analyze incoming audio signals and provides a precision frequency response measurement and spectral visualization.

It is available in a variety of applications, such as sound room tuning, speaker settings, audio equipment testing, stage setting measurement, evaluation of sound mixing environment and Investigation of noise environment.

Measurement function has two measurement modes, 1/3 octave mode and FFT mode.

1/3 octave mode
In this mode, you can measure the energy average value of each frequency band by frequency division in 1/3 octave x 30 bands. You can analyze spectrum in a specific frequency band, not the instantaneous frequency peak. It is suitable for more quantitative spectrum analysis.

New updated iOS app - "Low Frequency Detector" version 6.0

icon-lfd_v500.png

"Low Frequency Detector" has been updated to version 6.0 now!

The latest version supports iOS 17 and improves stability and performance.

"Low Frequency Detector" is a new acoustic measurement tool for detecting the low frequency sounds that is hard to hear in the normal situation.

It also allows you to examine the frequency component of the low frequency sounds by 1/3 octave band analysis and FFT analysis.

In general, the low frequency sound is a sound wave with 1 Hz to 100 Hz. By depending on its frequency component and sound level, it is different the degree of influence on the human body and the noise sensation.

The human ear is insensitive enough to become a low frequency. If you may be exposed to the noise of neighboring constructions and factories without noticing, you may have a feeling bad and a sense of oppression. In this case, you can check what type of low frequency sound exists by simple operation of this app.

Please use this app to find out whether or not low frequency sounds are present and their sources and to help with noise control.

The following are some of the sources of the low frequency sounds.

# Sources in the home: heat pump water heaters, household fuel cells, ventilation fans, refrigerators, air conditioners, blowers, dehydration pumps, etc.

# Outdoor sources: cars, trains, airplanes, outdoor air conditioning units in buildings, factory noise, long-term vibration of road bridges, wind power generation, etc.

If you have unexplained health problems or feel unwell, you may be exposed to such low frequency sounds.

New updated iOS app - "Mosquitone Detector" version 5.0

icon-mtd_v400.png

"Mosquitone Detector" has been updated to version 5.0 today!

The latest version supports iOS 17 and improves stability and performance.

"Mosquitone Detector" is a sound measurement app that detects high-frequency noises and ultrasonic sounds hard to hear for human ears.

It may have been exposed to artificial high-frequency noise while you do not notice. This app can detect and visualize such high-frequency noises.

mtd-detect-16k-1_v400.jpg mtd-search-16k-1_v400.jpg

# Detect mode: It can check if there are high frequency and ultrasonic sounds that you cannot hear.

・Frequency spectrum (pie chart)
The pie chart displays a detailed frequency spectrum and is displayed in color gradation according to the intensity of the noise level for each frequency. Normal levels are blue to green, yellow for stronger vigilance levels, and red for stronger danger levels, as described below.

- Normal level (less than 75dB) : Blue / Green
- Warning level (75dB or more, less than 85dB) : Yellow
- Hazardous level (85dB or more) : Red

・Frequency band sound level (bar graph)
The bar graph is the frequency band sound level, and displays the noise status in 1kHz unit bands.
It detects the strongest high-frequency components and displays the peak frequency bar and measured values (frequency and level) as reference information. This peak frequency is constantly updated.

* Measurement case with high-frequency band above 16 kHz; high-frequency noise found around 21.3 kHz! As noise level is not so loud, the display range is adjusted and enlarged.

mtd-detect-16k-2-1_v400.jpg mtd-detect-16k-2-2_v400.jpg mtd-detect-16k-2-3_v400.jpg

* Measurement case with high-frequency band below 16 kHz; high-frequency noise with large gain level was found around 15.1 kHz!

mtd-detect-8k-1_v400.jpg

# Search mode: It can find the direction of high-frequency sound source.

Tap "Start" button, hold the iPhone device firmly in your hand, and make one slow clockwise (rightward) rotation (360 degrees horizontally) to search for the direction of the high-frequency sound source. The red bar on the pie chart and the angle display shows the direction of the sound source.
