A digital wireless audio transmission system having a wireless receiving unit for wirelessly receiving a high-frequency signal. An HF analysis unit analyzes the received high-frequency data, detects errors in the transmission within a time window, and outputs the received data and first items of information in respect of the detected errors. A decoding unit converts/decodes the received high-frequency data into audio data. An error detection unit checks errors in the conversion of the decoding unit within a previously established time window and outputs second items of information in respect of errors during decoding of the received high-frequency data. An error rate is determined based on the first and second items of information. If the error rate exceeds a first threshold value then no audio signal is outputted. Only if the error rate falls below a second value, lower than the first value, is an audio output is then again effected.

Digital wireless audio transmission system

A digital audio transmission system, in particular a wireless microphone or wireless pocket transmitter system. The audio transmission system has at least one wireless transmitter and at least one wireless receiver. The wireless transmitter has an analog input, a digitally adjustable input potentiometer for adjusting the input gain, an analog/digital converter for converting the analog signals into digital signals, a digital signal processing unit for performing digital signal processing, and a digital or a digitally adjustable output potentiometer for adjusting the output gain. The digital signal processing unit is adapted to adjust the gain of the digital input potentiometer and/or the digital output potentiometer in such a way that the dynamic range of the analog/digital converter is optimally utilized.

Digital wireless audio transmission system with optimized dynamics

There is provided a wireless transmission system comprising at least one mobile transmitter for wireless audio transmission having a user interface. The wireless audio transmission system further has a stationary receiver for receiving the wireless audio transmission from the at least one mobile transmitter. The receiver has a receiving unit for wirelessly receiving the audio signals transmitted from the mobile transmitters. The stationary receiver also has an audio processing unit for performing audio processing of the audio signals received by the receiving unit and a sound check unit for analyzing the wireless audio signals received by the receiving unit. The stationary receiver further has a transmitter for transmitting at least parts of the analysis of the sound check unit to the mobile transmitters by way of a return channel.
