Abstract
Movement of a sound source toward or away from a listener may be simulated by crossfading a sound level of a point sound source signal representation of a source waveform and a spherical harmonic representation of the source waveform as a simulated distance of a listener from a sound source changes to generate a cross-faded waveform. A speaker may be driven with the cross-faded waveform.
Claims23
A method for simulation of movement of a sound source towards or away from a listener, comprising:
- crossfading a sound level of a point sound source signal representation of a source waveform and a spherical harmonic representation of the source waveform as a simulated distance of a listener from a sound source changes to generate a cross-faded waveform;
- and
- driving a speaker with the cross-faded waveform.
A system, comprising:
- a processor;
- a speaker;
- a memory coupled to the processor, the memory having executable instructions embodied therein, the instructions being configured to cause the processor to carry out a method for simulation of movement of a sound source towards or away from a listener when executed, the method comprising:
- crossfading a sound level of a point sound source signal representation of a source waveform and a spherical harmonic representation of the source waveform as a simulated distance of a sound source relative to a listener changes to generate a cross-faded waveform;
- and
- driving the speaker with the cross-faded waveform.
A non-transitory computer readable medium with executable instructions embodied therein wherein execution of the instructions cause a processor to carry out a method for simulation of movement of a sound source towards or away from a listener comprising:
- crossfading a sound level of a point sound source signal representation of a source waveform and a spherical harmonic representation of the source waveform as a simulated distance of a sound source relative to a listener changes to generate a cross-faded waveform;
- and 7 driving a speaker with the cross-faded waveform.
