"fo-Kannon" is a powerful Real-time Audio Spectrum Analyzer (RTA) app for the iPad. Now you can visualize the frequency spectrum of your sound environment!*** SPECIAL PRICE - 20% OFF FOR A LIMITED TIME ONLY! ***"fo-Kannon" uses our proprietary digital signal processing technology to analyze incoming audio signals, and provides a precision frequency response measurement and a spectral visualization. The measurement is displayed the logarithmic amplitude response in the frequency range of 20kHz from 20Hz, the 1/3 Octave band or the logarithmic FFT scale. From the Ver1.3, the improvement of response in the very low frequency and the calibration functionality has been added as new features. It became easy to use more sophisticated for the sound measurement."fo-Kannon" is available in a variety of applications, such as room tuning, speaker test, audio equipment test, adjust car audio system, stage setting measurement and evaluation of sound mixing environment. While adopting a digtal signal processing algorithms with high accuracy, "fo-Kannon" is designed to easy-to-use interface like a classical measurement instrument. *** Products information ***Recommend our new apps "Hearing Analyzer for Audiophile" for your ears wellness. It can be easily measured the frequency characteristics of your hearing. You will self-diagnose the audio listening ability. TOON,LLC is a company that seeks the comfort of sound environment based on our acoustic proprietary technology, and will provide tools for audio professional, sound technology, home theater installer, and anyone who loves audio.
