Abstract: A method for mixing of audio signals that allows maintaining of a consistent perceived sound level for the mixed signal by holding the sound level of the dominant signal in the mix constant by adjusting the sound level of the non-dominant signal(s) in relation to the dominant signal. It further includes receiving of a mixing balance input, which denotes the adjustable balance between the main and associated signals. It further includes identification of the dominant signal from the mixing balance input and mixing metadata, from which an appropriate scale factor for the non-dominant signal may also be determined directly from the scaling information, without the need for any analysis or measurement of the audio signals to be mixed. It further includes scaling the non-dominant signal in relation to the dominant signal and combining the scaled non-dominant signal with the dominant signal into a mixed signal.

Abstract: A wireless control and/or data acquisition system in an integrated circuit comprises a digital device and a wireless device, e.g., a radio frequency (RF) device, an infrared device (IrDA), etc. A micro-electro-mechanical (MEM) device may also be included in the integrated circuit package. The MEM may be used as a sensor, non-volatile memory, a filter, a frequency determining resonator, and/or a control device in combination with the digital device. The digital device and RF device may have independent power and signal connections for signal isolation between the digital device and RF device. Standby and sleep modes for the digital device and RF device reduce power consumption and low voltage operation enables the use of a simple battery power source.

Abstract: The invention relates to a method and an arrangement implementing the method for implementing the transmitter operation of a digital data transmission system. The method comprises the steps of converting an information signal to be transmitted into a first intermediate-frequency signal such that the first intermediate-frequency signal is processed to a desired frequency band, and converting the first intermediate-frequency signal into a variable-frequency signal on the above mentioned frequency band, and filtering away interference signals. The method further comprises the steps of mixing the first intermediate-frequency signal with a fixed-frequency signal in order to generate a second intermediate-frequency signal such that the second intermediate-frequency signal is a variable-frequency signal similarly as the first intermediate-frequency signal, converting the second intermediate-frequency signal into an output signal to a transmission band width which is in its entirety at a higher frequency range than the second intermediate-frequency signal, and converting the second intermediate-frequency signal into the output signal such that the output signal is adapted to frequency changes of the second intermediate-frequency signal.
