Abstract: A clock generator receives first and second clock signals, and input representing a desired frequency ratio. A comparison is made between frequencies of an output clock signal and the first clock signal, and a first error signal represents the difference between the desired frequency ratio and this comparison result.

A comparison is made between frequencies of the output clock signal and the second clock signal, and a second error signal represents the difference between the filtered first error signal and this comparison result. The second error signal is filtered. A numerically controlled oscillator receives the filtered second error signal and generates an output clock signal. As a result, the output clock signal has the jitter characteristics of the first input clock signal over a useful range of jitter frequencies and the frequency accuracy of the second input clock signal.

Abstract: A personalized room related transfer function (RRTF) for sound bars and speakers within a specific room is generated without the need for photographs of the listener's head or microphones in a headphone apparatus. A smart device aids the listener in creating his own RRTF by enabling the listener to select a general RRTF model based on the specific sound bar setup (e.g., sound bar; sound bar+subwoofer; sound bar+rear speakers+height; etc.) from a set of general RRTFs downloaded locally or from the cloud. A test signal is played from a specific driver of the sound bar, and the listener identifies a location at which he would like the perceived sound to originate. If the driver location signal and desired location are not the same, the app adjusts parameters and replays the test signal until the driver signal and the desired location are the same.

Abstract: A method for receiving audio data streams with mobile devices in different rooms in which sound is emitted via loudspeakers. Each mobile device connects over a local wireless network to a server that controls the sound emitted in the rooms via loudspeakers. Each mobile device detects room information, emitted only in the corresponding room, that indicates the room the respective mobile device is in. The room information is transmitted from each mobile device to the server. The server associates each room information with an output audio data stream that corresponds to the sound emitted via loudspeaker in the respective room in which the mobile device has detected the room information. The server assigns to each of the mobile devices an output audio data stream corresponding to the respective room information, and transmits the output audio data stream over the local network to the mobile device, which receives and replays it.
