Abstract: Systems include a receiver configured to detect signals corresponding to a stream of digital symbols, a signal demodulator coupled to the receiver and configured to process an incoming stream of digital symbols, and a computing device connected to the receiver and to the signal demodulator, and featuring a set of software instructions that, when executed by the computing device, causes the computing device to determine an estimated time delay associated with the stream of digital symbols, transmit control instructions to the signal demodulator to configure the signal demodulator according to the estimated time delay, and process at least a second subset of the stream of digital symbols using the configured signal demodulator.

Abstract: Methods and systems for assisting tonally-challenged singers. A microphone can be integrated with a sound reinforcement system used in a live performance. The microphone, which can transduce the performer's voice, can serve multiple purposes such as, for example, to feed input to the natural ear and to the sound reinforcement system. The processed sound of the performer's voice (with fundamental frequency emphasized) can be mixed into the signal fed to a stage “monitor” speaker facing the performer or a headset worn by the performer.

Abstract: A method and apparatus to facilitate tone challenged singers to sing intended notes. In one aspect, the singer determines a note to sing corresponding to an intended frequency fi. The singer utters a note continuously with fundamental frequency fu into a microphone of the natural ear apparatus. The note is processed by the apparatus to produce sound emphasizing the fundamental frequency fu and output through a speaker to the auditory organs of the singer. The singer detects differences between intended frequency fi and uttered fundamental frequency fu. The singer adjusts his vocal organs as he utters the note with the intention of changing fu to reduce difference between fi and fu.
