Seamless reverberation transition in virtual venues

An audio system comprising:

• a memory storing instructions;
• and
• at least one processing unit, which when executing the instructions is configured to perform the steps of:
• receiving an input audio signal;
• obtaining a first set of reverberation parameters associated with a first acoustic environment;
• obtaining a second set of reverberation parameters associated with a second acoustic environment, the second set of reverberation parameters being different from the first set of reverberation parameters;
• simultaneously processing the input audio signal by:
• generating a first early reflections signal based on simulating first-occurring sound reflections of the input audio signal within the first acoustic environment using the first set of reverberation parameters, and
• generating a second early reflections signal based on simulating first-occurring sound reflections of the input audio signal within the second acoustic environment using the second set of reverberation parameters;
• combining the first and second early reflections signals through a fading process to generate a transitional early reflections signal, which comprises a transition from the first to the second early reflection signal in accordance with the fading process;
• and
• providing an output audio signal comprising a combination of the input audio signal and the transitional early reflections signal.

One or more non-transitory computer readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:

• receiving an input audio signal;
• obtaining a first set of reverberation parameters associated with a first acoustic environment;
• obtaining a second set of reverberation parameters associated with a second acoustic environment, the second set of reverberation parameters being different from the first set of reverberation parameters;
• simultaneously processing the input audio signal by:
• generating a first early reflections signal based on simulating first-occurring sound reflections of the input audio signal within the first acoustic environment using the first set of reverberation parameters, and
• generating a second early reflections signal based on simulating first-occurring sound reflections of the input audio signal within the second acoustic environment using the second set of reverberation parameters;
• combining the first and second early reflections signals through a fading process to generate a transitional early reflections signal, which comprises a transition from the first to the second early reflection signal in accordance with the fading process;
• and
• providing an output audio signal comprising a combination of the input audio signal and the transitional early reflections signal.
