An audio/video processing system combines a locally generated audio signal with pre-recorded audio/video programming to produce combined audio/video output. The audio/video system allows users to generate sound locally, mix them with the audio content of a pre-recorded audio/video program, and allows combined output to be presented by home audio/video system video displays and the speakers. The audio/video system provides independent sound characteristic control capability, such as volume control settings and voice and tone alterations settings and the equalization settings, for the various sound components produced in the process of mixing locally generated sounds. The sound components produced in the process of mixing include locally generated sound components, such as the voice sound component, the musical instrument sound components, and the sound components of the pre-recorded audio program such as voice, musical instrument and the background sound components. The pre-recorded audio/video programs may be obtained on the pay-per-view basis.
