A method for processing audio signals in a radio transmitter, includes: receiving an analog audio sample stream and a digital audio sample stream; determining offsets in time between the analog audio stream and the digital audio stream using a normalized cross-correlation of audio envelopes of the analog audio sample stream and the digital audio sample stream; filtering the determined offsets in time to produce filtered offset values; determining an alignment slip adjustment value as a function of the filtered offset values; aligning the analog audio sample stream and the digital audio sample stream using the determined alignment slip adjustment value; and generating a hybrid radio signal for broadcast that includes time-aligned analog audio and digital audio.

Systems, methods, and processor readable media are disclosed for detection of signal quality problems and errors in digital radio broadcast signals. First monitoring equipment is located in an over-the-air coverage area of a first radio station. Second monitoring equipment is located in an over-the-air coverage area of a second radio station. The first and second monitoring equipment are configured to receive digital radio broadcast signals from the respective first and second radio stations. A computing system is configured to receive data from the first monitoring equipment and the second monitoring equipment, the data being indicative of one or more attributes of a digital radio broadcast signal received at respective monitoring equipment. The computing system analyzes received data to detect a signal quality problem or error in the digital radio broadcast signals received at the first and second monitoring equipment.

A system is described for maintaining synchrony of operations among a plurality of devices that have independent clocking arrangements. The system includes a task distribution device that distributes tasks to a synchrony group comprising a plurality of devices that are to perform the tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to the members of the synchrony group over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which the members of the synchrony group are to execute the task. Each member of the synchrony group periodically obtains from the task distribution device an indication of the current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.

In one example, a system includes: a circuit board; at least one tuner adapted on the circuit board to receive and process a radio frequency (RF) signal to output a downconverted modulated signal; a processor adapted on the circuit board to demodulate the downconverted modulated signal, process the demodulated downconverted signal and output an audio signal; a location on the circuit board to receive a demodulator circuit; and a shunt element adapted on the circuit board to direct the downconverted modulated signal from the at least one tuner to the processor when the system does not include the demodulator circuit.
