  • What is the relation between amplitude and frequency ...

    For any wave, the amplitude can be anything. There is a simple relationship between wavelength, frequency, and velocity. You can see this easily: a wave travels one wavelength L in one period P, so v = L/P. The period P is defined as the inverse of the frequency f, so P = 1/f.

    Aug 30, 2016  The amplitude of an audio signal is a measure of how high (and low) the wave extends from the x axis. For the sine waves we've been working with so far, this has been 1, since 1 (and -1) has been the maximum value these waves take.. Changing the amplitude of a signal is straightforward: We just need to multiply each sample with some constant number.
