"fo-Onmon" is a spectrogram analyzer application for Audio and Voice band. It uses the Fast Fourier Transform to analyze incoming audio signals and provides a precision frequency response measurement. "fo-Onmon" is a visual representation of the spectrogram of frequencies in a sound as they vary with time in the frequency range of 22kHz 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. In the latest Ver3.0, the response of low frequency have been improved.Audio mode has followed the conventional function, which can be displayed simultaneously Spectrogram and Spectrum as the target of audio signal. This mode makes a real-time spectral analysis of the sounds around you. It can be used for discovering visual hidden images in the various sounds, such as music, birdsongs and environmental sounds. You can also be used to capture an unpleasant high-frequency noise in your audio 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.TOON,LLC is a company that seeks the comfort of sound environment based on our acoustic proprietary technology, and we will provide tools for audio professional, sound technology, home theater installer, and anyone who loves audio.
