Systems and methods to deliver live sound with enhanced quality conveyed by a mixing desk to a mobile computing device user contemporaneously with external live sounds. The mobile computing device is operable to receive enhanced audio signals produced by a remote audio signal processing device through a communication work. A memory resident application is configured to playback the enhanced audio signals in phase with the external sounds using an audio rendering device. An attendee at the live event can hear the sounds from the playback through an earphone coupled to the mobile computing device as well as from the ambient environment.
