Description

Proximity-based sound morphing for accurate sound representation of real-life locations Cross Reference to Related Applications The present application claims the benefit of U.S. provisional patent application No. 63/719,581 entitled "PROXIMITY-BASED SOUND MORPHING FOR ACCURATE SONIC REPRESENTATION OF REAL-LIFE LOCATIONS" filed on 11/12 of 2024. The subject matter of this related application is incorporated herein by reference. Technical Field Embodiments of the present disclosure relate generally to audio systems, and more particularly to proximity-based sound morphing for accurate sound representation in real-life locations. Background Vehicles include sound systems that are typically used to play audio content, such as radio broadcasts, streaming music and podcasts, audio books, stored recordings, and/or other types of audio content, using one or more speakers. The vehicle audio system provides different levels of sound customization. For example, conventional vehicle audio systems allow a user to adjust relatively coarse sound settings such as volume, equalization, balance, faders, and the like. However, in most vehicle audio systems, sound playback is typically limited to reproducing music or other audio as close as possible to the audio source. Many users enjoy or even prefer live music and other sound experiences, rather than just listening to the original recorded version of the audio content. However, conventional audio systems deployed in vehicles or other listening environments often have limited ability to adjust the audio content. For example, many audio systems only allow a user to select bass, midrange, or treble settings in a relatively basic manner, which cannot simulate or reproduce a live music experience. Accordingly, there is a need for improved techniques to provide customized capabilities for audio played back by an audio system in a listening environment. Disclosure of Invention Various embodiments disclose a computer-implemented method for generating audio effects in a listening environment. The computer-implemented method includes determining, for each of a plurality of sound sources near a user-selected location, a distance between the user-selected location and a location of the sound source. The computer-implemented method further includes determining an amplitude of each of the plurality of sound sources based on the determined distance between the user selected location and the location of the sound source, and mixing the plurality of sound sources based on the determined amplitudes. Further embodiments provide, among other things, one or more non-transitory computer-readable media and systems configured to implement the methods set forth above. At least one technical advantage of the disclosed method over the prior art is that, with the disclosed techniques, a user of an audio system can select and customize a simulated listening environment to enjoy audio output through the audio system. The simulated listening environment causes audio effects to be applied to sounds output by the audio system and approximates different types of live music experiences according to user preferences. Thus, the user enjoys an enhanced personalized auditory experience in the listening environment. These technical advantages provide one or more technical improvements over prior art methods.
