摘要： An amplifier unit suitable for a wide variety of uses, which can flexibly support diverse sound recording scenarios, and a mobile electronic device provided with the amplifier unit. An amplifier unit has microphone/line input terminals respectively provided on the topside surface and the left side surface. When a connector is connected to a mobile electronic device, stereophonic sound is recorded using one of the terminals when the mobile electronic device is held in portrait orientation, and using the other terminal when the mobile electronic device is held in landscape orientation. It is possible to switch each of audio signals coming through the two terminals between monophonic and stereophonic.

摘要： The Radio Data System (RDS) protocol promulgated by the European Broadcasting Union provides for alternate frequencies (AF) for the same broadcast. Receivers periodically switch over to such an alternate frequency, leading to momentary crackling noises. In a radio receiver having a device for temporary switchover from a received frequency to some other frequency, substitute signals are inserted into the audio signals that are interrupted during the temporary switchover. The substitute signals are formed from the audio signals before and optionally also after the temporary switchover.

摘要： A method comprises detecting whether or not a frequency modulation broadcast receiver is tuned to an overdeviated frequency modulated broadcast, or is at a location where overdeviated frequency modulated broadcasts exist or has received a user input indicating the presence of an overdeviated frequency modulated broadcast; and in response to the detection, automatically adjusting operation of the frequency modulated broadcast receiver. Automatically adjusting operation comprises adjusting one or more parameters or settings in such a way as to alter the susceptibility of a speaker arrangement to the possibility of being overdriven by overdeviated frequency modulated broadcasts.

摘要： A video-audio recording and reproducing apparatus (101) has a built-in stereo microphone (21a, 21b) and an external microphone connection terminal (32). The external microphone connection terminal (32) is connected to a binaural microphone (3) to be attached to the ears of a photographer (300). When the binaural microphone (3) is used to collect ambient sounds, an audio signal to be recorded on a recording medium is switched from an audio signal from the built-in stereo microphone (21a, 21b) to a binaural audio signal from the binaural microphone (3). The photographer (300) puts the binaural microphone (3 (31a, 31b)) on his or her ears and collects ambient sounds around the photographer (300) including a sound emanating from an object. The object is photographed with a camera unit (11). The recording medium records the binaural audio signal, a photographed video signal, and a binaural flag signal.

摘要： Systems and methods are disclosed that may be implemented to process a received RF spectrum that includes both analog modulated and digitally modulated RF signals to blend between a digital demodulated signal and an analog demodulated signal obtained from the received RF spectrum prior to performing one or more signal quality mitigation operations on the blended signal (e.g., such as stereo blend, hi-cut, etc.). In one embodiment, the digital demodulated signal and the analog demodulated signal may include at least some of the same information, e.g., such as information from simulcast digital and analog channels that are obtained from the same received RF spectrum.

摘要： A method for processing an input composite signal includes tracking a signal component of the input composite signal according to a frequency of a pilot signal to generate a locked signal, detecting an amplitude of the signal component to generate a detecting result, and generating a reproduced pilot signal according to the detecting result and the locked signal. A frequency and a phase of the locked signal are substantially identical to the frequency and a phase of the pilot signal.

摘要： A receiver may estimate a channel condition based on a difference between a pilot energy signal and a filtered pilot energy signal. The receiver may further switch to a stereophonic mode when both the difference and an energy level of the pilot energy signal satisfy a predetermined requirement of the receiver, and switch to a monophonic mode when either the difference or the energy level of the pilot energy signal fail to satisfy the predetermined requirement of the receiver.
