Enhancing artificial reverberation in a noisy environment via noise-dependent compression

A system, comprising:

• a sensor configured to generate a signal indicating a current noise level in a listening space;
• a loudspeaker configured to output sound in the listening space based on an output signal;
• and
• at least one processor configured to execute instructions to:
• generate an artificial reverberation signal based on a source signal and a response of the listening space, wherein the artificial reverberation signal includes a first low output-level portion having output levels that are below a compression threshold level and a first high output-level portion having output levels that are above the compression threshold level;
• generate a compressed artificial reverberation signal based on the artificial reverberation signal by increasing the output levels of the first low output-level portion by a first magnitude and increasing the output levels of the first high output-level portion by less than the first magnitude;
• and
• combine the compressed artificial reverberation signal with the source signal to form an output signal for the listening space.

A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor, configure the at least one processor to perform the steps of:

• generating an artificial reverberation signal based on a source signal and a response of a listening space, wherein the artificial reverberation signal includes a first low output-level portion having output levels that are below a compression threshold level and a first high output-level portion having output levels that are above the compression threshold level;
• generating a compressed artificial reverberation signal by increasing the output levels of the first low output-level portion by a first magnitude and increasing the output levels of the first high output-level portion by less than the first magnitude;
• and
• combining the compressed artificial reverberation signal with the source signal to form an output signal for the listening space.
