"SpectraWave" transforms your iPad into a real-time FFT Analyzer.SpectraWave is a Monaural FFT Analyzer that examines an audio signal's frequency. It also shows the frequency of a sound in a graph.Features・The FFT Analyzer focuses on the human audible range (up to 20kHz).・The vertical axis shows each frequency volume in dB, while the horizontal axis shows a logarithmic frequency scale in Hz.・Adjust the volume using the input volume slider on the right side of the main window.・Suitable for detecting a howling frequency or for room tuning.・Corresponds with built-in mike or headphone and common-mike.・Indicates live peak frequency.・Has the Oscillator function. Can bring up sign wave, ripple wave, pink noise and white noise.・Oscillator wave can set the frequency and the volume.・Features an in-app web browser. Access the web for information without switching applications. (Available only where there is an Internet connection.) Tools1st screen "FFT"・By adjusting the slider of FFT input-gain volume you can lower the input-gain.・Select a FFT Size from 256, 512, 1024, 2048 and 4096. The higher number, the more detailed the frequency analysis and the slower the display speed.・Has built-in speaker or Oscillator that can output from headphone.・Oscillator has independent volume apart from the input gain. 2nd screen "Web info"・Features an in-app web browser. Access the web for information without switching applications. (Available only where there is an Internet connection.)Uchu Sokudo LabFollow us: https://twitter.com/uchulab
