A recently granted patent (Publication Number: US11922921B1) discloses a system for generating a custom audio experience in a vehicle. The system includes processors and memory storing instructions to receive audio samples of impulse responses from the vehicle's interior and audio equipment, generate convolution reverbs, modify user audio samples based on these reverbs, and output the modified audio. The system can also remove non-audible samples, tag audio samples with the vehicle, and store convolution reverbs for future use. Additionally, the system can assess the vehicle's audio quality based on acoustic properties and publish an audio quality score on a webpage associated with the vehicle.

Furthermore, the system allows for customization by receiving user audio samples, modifying them based on convolution reverbs, mapping additional reverbs to tonal selections, and generating modified audio based on user input. The system ensures a tailored audio experience by combining impulse responses and convolution reverbs, adjusting audio settings to flat, and utilizing omnidirectional microphones for accurate audio sampling. The patent also emphasizes the importance of removing non-audible samples from audio inputs to enhance the quality of generated convolution reverbs. Overall, the system aims to provide users with a personalized and high-quality audio experience in their vehicles, backed by innovative technology and precise audio processing techniques.
