Sine wave is defined as 'a curve representing periodic oscillations of constant amplitude as given by a sine function.' Sine waves are sometimes described as "pure tones" because they represent a cons…

[equation caption=”Equation 2.1″]A single-frequency sound wave with frequency f, maximum amplitude A, and phase θ is represented by the sine function $$!y=A\sin \left ( 2\pi fx+\theta \right )$$ where x is time and y is the amplitude of the sound wave at time x .[/equation]

I recently learned that an audio sine wave is called that way because it is of the shape of the graph of a sine function. So (correct me if I'm wrong), the equation for a sine function is: $$p = \sin(t)$$ Where: $p$ is the point on the graph, and $t$ is the point in time. Writing this in Wolfram Alpha indeed shows the expected graph.

The amplitude of a sine wave with frequency $f$ Hertz at time $t$ seconds is $$a(t) = A_0\sin(2\pi ft)$$ where $A_0$ is the maximum amplitude. The argument to the $\sin$ function is in radians, which is why we need to multiply by $2\pi$, which is one revolution in radians. This means that the amplitude $a(t)$ repeats every $\frac 1 f$ seconds.

On The Mathematics of the Sine Wave y(x) = A*(2πft + ø) Why the understanding the sine wave is important for computer musicians. The sine wave is mathematically a very simple curve and a very simple graph, and thus is computationally easy to generate using any form of computing, from the era of punch cards to the current era of microprocessors.

Musical notes can be thought of in terms of sine curves where we have the basic formula: y = sin (bt) where t is measured in seconds. b is then connected to the period of the function by the formula period = 2π/b. When modeling sound waves we normally work in Hertz – where Hertz just means full cycles (periods) per second.

Here's a piece of the graph; click on the link below the picture to hear the sound this function creates. Play the note A. If we change the number of cycles the wave completes every second -- in other words, if we change the period of the sine wave -- then we change the sound. Here are the equations and graphs of two other notes, C Sharp (C# ...

The sound of a sine wave signal Sine wave mathematics The sine wave is called a sine wave because it follows the pattern of the geometric value of sine over the complete cycle. y ( t) = A sin ( ω t + φ) Where: A = amplitude, the peak deviation of the function from zero. f = frequency, measured in cycles per second, i.e. Hertz, Hz.

If we want to change the amplitude of our sine wave, we can insert a value for A. If A > 1, we may have to alter the range of the vertical axis to accommodate the higher amplitude, as in. fplot('2*sin(262*2*pi*t)', [0, 0.05, -2.5, 2.5]); After multiplying by A=2 in the statement above, the top of the sine wave goes to 2 rather than 1.
