Source

Sources are the only sound emitters available in wavefront. They emit sound in all 4 directions (top, left, right, bottom) and can be placed anywhere in the render area. Each source can be assigned a number of properties, such as frequency, amplitude and phase, depending on the waveforms used.

The following waveforms are available for sources:

• Sine
• Gaussian
• White Noise

Sine

The sine waveform is a simple waveform that oscillates in the range of \([-a, a]\) (where \(a\) is the amplitude). It is the most basic waveform and is used to represent a pure tone. The following parameters can be set for the sine waveform:

• Frequency: The frequency of the sine wave in Hz.
• Amplitude: The amplitude of the sine wave (unitless).
• Phase: The phase of the sine wave in degrees.

Gaussian

The Gaussian waveform is a periodic bell-curve that is used to represent a short impulse. The following parameters can be set for the Gaussian waveform:

• Frequency: The frequency of the curve in Hz.
• Amplitude: The amplitude of the curve (unitless).
• Phase: The phase of the curve in degrees.
• Standard Deviation: The standard deviation (width) of the Gaussian curve.

White Noise

The white noise outputs random noise at all frequencies. The following parameters can be set for the white noise waveform:

• Amplitude: The amplitude of the noise (unitless).
