Abstract: A media processing method that dramatically improves the perceived audio quality and audio output level and video quality and video display consistency for most commonly used audio and video recording, storage and playback systems. The system synthesizes and boosts harmonics and spectral ranges that have been diminished or are missing in the audio component of media files and also processes the audio component to allow maximum playback level without distortion, while also insuring that the perceived audio playback level between different media files stays consistent. The system also improves the listening experience for users of headphones or ear buds. The system also improves the video image color range and brightness for best display on particular display devices while also insuring that the image brightness and color intensity stays consistent even when viewing media files containing video from a variety of different sources.
