A system for performing loudness normalization based on user feedback is described herein. The system includes a content delivery system and a plurality of audio playback devices. The audio playback devices may communicate volume settings used during playback of pieces of sound program content to the content delivery system. Based on these collected data points, a statistical analysis may be performed to generate loudness adjustment values for pieces of sound program content. The loudness adjustment values may be communicated to the audio playback devices through metadata in associated pieces of sound program content or as separate communications from the content delivery system. An offline version is also described that supports individual loudness normalization adjustments based on a single user's preferences. Under either system, loudness normalization may be achieved based on real world volume settings for individual pieces of sound program content played using various playback configurations.
