A wireless audio transmission system includes: a transmitter having a microphone and a modulator-transmitter transmitting a radio wave modulated by an audio signal from the microphone; a receiver having a receiver-demodulator demodulating the audio signal after receiving the radio wave transmitted from the transmitter, outputting the audio signal demodulated by the receiver-demodulator to the outside of the receiver; and a video camera into which the audio signal output from the receiver is input, wherein the receiver has a detector detecting frequencies of a radio wave not being used by other devices based on a reception level of the radio wave received by the receiver-demodulator and outputs available frequency information indicating the frequencies detected by the detector to the video camera, and the video camera has a controller causing the available frequency information input from the receiver to be displayed on a display unit attached to the video camera.

A variable speed reproduction of speech from memory depending on the indication of a jog dial, is accomplished by buffer memory (23) for speech sound and a jog dial (17) for controlling a read speed from this memory. Speech sound data is read out from the buffer memory (23) at a speed corresponding to the indication of the jog dial (17). The speech sound data is reproduced, independent of the jog dial (17), from a tape (13) and is written into the memory (23). A capstan motor drive circuit (18) detects the difference between the read address and the write address of the memory (23) and controls the reproduction speed of the sound speech data from the tape (13) in accordance with this difference. Since the read speed is directly controlled for the memory (23), no time delay exists between the speed command and the actual variable-speed reproduction. The address difference between write and read of the memory (23) is always monitored to keep the buffer from becoming empty so that continuous reproduction can be made, and so that, when the speech sound is edited, variable-speed continuous reproduction can be made for speech editing by the buffer memory (23) alone.

A method and an apparatus for automatically editing audio signals by determining an editing section on a recording medium having the signals recorded thereon. A first editing point is searched for on the recording medium, and the location of that point is stored in a memory. A second editing point is searched for on the recording medium. The location of the first editing point is compared with that of the second editing point. One of the two locations is set as an in-point and the other location as an out-point in accordance with the result of the comparison. The editing section determined by the in- and out-points is displayed on a screen.
