"Onmon" is Spectrogram Analyzer app for Audio and Voice band.
It uses the Fast Fourier Transform (FFT) processing to analyze incoming sound signals and provides a precision frequency response measurement for the spectrogram analysis.
"Onmon" is a visual representation of the spectrogram of frequencies in a sound as they vary with time in the frequency range of 24kHz from 20Hz.
The spectrogram is a graphical image with two geometric dimensions that the horizontal axis represents time and the vertical axis is frequency, and the addtional third dimension is indicating the amplitude of a particular frequency at a particular time that is represented by colour of each point in the image.
This app has two analysis modes, Audio mode and Voice mode.
Audio mode performs a real-time spectral analysis as the target of audio signal by Spectrogram and Spectrum. It can be used for discovering visual hidden images in the various sounds, such as music, birdsongs and environmental noises. You can also be used to capture an unpleasant high-frequency noise in your sound system.
Voice mode performs the frequency domain analysis as the target of voice signal, which can be displayed simultaneously Spectrum, Cepstrum, Envelope, Formant and Spectrogram. It can be used for visualization analysis of voices, speech, vocal, and squeaking sound of the animal.
In addition, this app is equipped with the replay function, so you can see the spectral analysis results offline.

Note:
At the time of the first access to Microphone and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app can not access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Photos or Microphone".
Please visit our iOS App Support page for more information on this app.
