The exemplary embodiments relate to methods and systems for a real-time localized audio broadcast to attendants at live entertainment events. The computer is adapted for receiving signals from the microphone, and for executing audio processing software for processing the microphone signals for converting them into compressed, digital audio signals and transmitting these signals via the communications link to the link device. A data cache is coupled to the microprocessor and configured to store the set-up information. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X00D861 through backcross conversion andor transformation, and to the maize seed, plant and plant part produced thereby. In other embodiments, a biodegradable polymer, an amide wax, optionally a plasticizer, and optionally a rosin are added to a cellulose-ester-based coating to drastically increase moisture resistance.
