Stereo Method for Simulating Localization

The direction of the sound may also be simulated by changing the relative intensities at the speakers.

Figure 7: Stereo method for simulating localization cues.

The location may be specified by parameter $x$.

The power in the signal is allocated according to the value of $x$:

• the power in the left speaker is given by $x$
• the power in the right speaker is given by $1-x$.

Because $x$ represents power, its sqare root is applied to the amplitude.
