Noise Level & Spectrogram - New Release!


"Noise Level & Spectrogram" is a sound level meter app for iPhone to easily measure the sound level of noise and music in your living environment. It is provided fully free of charge.

Just tap the start button to measure sound levels in decibels (dB) and display the time variation of the sound level. You can also visually check the frequency characteristics of the sound source in spectrogram.

Reverb Time Analyzer - New Release!


"Reverb Time Analyzer" is an acoustic analysis tool that allows you to measure the reverberation time of a room.

Knowing the reverberation time will be one of the guidelines to build a comfortable sound space. For example, it can be obtained as objective data for the current status of various acoustic disturbances, such as high room reverberation and poor intelligibility, too much flutter echo and howling.

This app can analyze the reverberation time using the interrupted noise method, in which a random test noise signal is generated from the iPhone's speaker and then turned off. Up to 6 consecutive measurements, reverberation time analysis, and spectrogram analysis can be performed.

Pitch On Stave - Singing voice pitch monitor


"Pitch On Stave" is a vocal support tool to help you improve your singing voice. It allows you to visually check the pitch of your singing.

You just sing into the built-in microphone on your iPhone, and it can graph the estimated vocal pitch on the stave. Try to improve your singing by checking your vocal pitch!

Audio Frequency Analyzer


"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.

"Audio Frequency Analyzer" 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.



"Magnetscape" is a new measurement app that observe invisible magnetic fields by using a built-in iPhone magnetic sensor.

It can monitor the surrounding magnetic field in real time, it can be used for various purposes in real life. For instance, it can be used for investigation of static magnetic field, search for low electromagnetic field at alternating magnetic field (electromagnetic field), metal detection and more.

Vibroscope - Vibration Measurement and Analysis Tools


"Vibroscope" is a vibration measurement and analysis tools by using the iPhone's acceleration sensor in real-time.

It allows you to monitor by visualizing the low-frequency vibration, such as inaudible by ear.

High-Frequency Noise Monitor


"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.

This app collects randomly fluctuating high-frequency noise from the iPhone built-in microphone and performs frequency analysis in real time. In addition, it retains the PCM data for 20 seconds just before the measurement is stopped, and displays a spectrogram of FFT and octave band analysis.

Audio Tone Generator Plus


"Audio Tone Generator Plus" is a new integrated sound signal generator app that produces a variety of audio test tones.

This app can be used in a wide range of fields as a reference sound source for audio system testing, sound tuning, hearing testing, SR fields and more. It has four different signal generators and can generate sinusoidal signals, frequency sweep/warble signals, chirp signals, and color noise with octave band noise.

Sound Level Analyzer PRO


"Sound Level Analyzer PRO" is an integrated sound measurement iPhone app with sound level measurement and powerful sound analysis tools.

It can display automatically the instantaneous sound level such as environmental noise, specific sound sources, live sounds in real-time.

This app has advanced sound analysis functions that can perform "Power Spectrum Analyzer", "Time Course graph", and "Statistical Analysis (Histogram, Percentile Level)". It can be used to analyze characteristics and trends of occurrence for the noise/sound source.

In addition, we have released a standard SLM app "Sound Level Analyzer" that simplified the sound analysis function of "Sound Level Analyzer PRO".

Low Frequency Detector


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

It supports very lower frequency range less than 100Hz by our proprietary sound sensing technology. This app can also display the frequency component of the low frequency sound by examining by 1/3 octave band analysis and FFT analysis.

Mosquitone Detector - Find the mosquito noise!


"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.

Octave-band Colored Noise


"Octave-band Colored Noise" is a new sound generator app that can generate various colored noises and octave-band noises.

It can be used for various purposes such as sound masking, sound effects for tinnitus relief and sleep, reference sound source for sound equipment measurement, sound tuning, and sound insulation effect measurement for buildings.

Hearing Analyzer Portrait


"Hearing Analyzer Portrait" is an ear wellness application that can be easily measured the frequency characteristics of your hearing.

It can graphically display and confirm your hearing in the audio band (30Hz - 20kHz). It supports your ear health to keep listening to good sound all the time.

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!
