Description

From the listing uploaded by “appupdater”.

This is a sound or signal generator with one oscillator. It can play custom wave form so you control the number, direction, amplitude and sharpness of the peaks. This instrument clearly demonstrates the physics of the sound and most importantly you can see that humans do not hear frequencies but amplitude acceleration (or peak sharpness). Also the peak position or direction inside the sound wave has no impact of human perception for the sound. You can even hear 0.2Hz sound of the peak is sharp enough and the frequency (self repetitiveness) of the signal is not actually meaningful for our ears. In nature there are no perfectly repeated waves and the sound has more free wave nature so what is important for our sound recognition abilities is the peaks sharpness and the number and amplitude of those peaks :) Frequency domain and FFT for music can’t be more wrong and misleading. So work in time domain and handle those peaks to move the science and music ahead! The app can be used for physics, music or sound, education or what ever. Oscillator range 0.2Hz - 20KHz Arbitrary waveform with up to 20 peak control points. Peak width control slider.
