No, that statement is not accurate. The position of the slides on a sound equalizer does not directly illustrate the combined amplitude and period of the sound wave produced by various instruments being played.
A sound equalizer is a device used to adjust the balance of different frequency components in an audio signal. It consists of multiple sliders or knobs that control the level or intensity of specific frequency bands. Each slider corresponds to a specific frequency range, such as bass, midrange, or treble.
The purpose of an equalizer is to adjust the relative amplitudes of different frequency components in an audio signal to achieve the desired tonal balance. It can boost or attenuate specific frequencies to enhance or reduce their presence in the overall sound. The sliders on a sound equalizer control the gain or attenuation of specific frequency bands but do not directly represent the amplitude or period of the sound waves.
The combined amplitude and period of a sound wave produced by various instruments playing together are determined by the properties of each instrument, their individual waveforms, and the superposition of these waves. The sound equalizer allows you to adjust the relative levels of different frequencies but does not provide information about the individual instruments' amplitudes and periods or the combined waveform of the sound produced.
