摘要： In an echo effector for imparting an echo effect to an audio signal based on values of a plurality of parameters, a memory is provided for memorizing an interrelationship among the plurality of the parameters which are mutually related to each other. A dial is actuated for independently setting one or more of the parameters to desired values. A microcomputer dependently sets the remaining parameters to appropriate values according to the desired values and the memorized interrelationship. Further, in a sound field effector operative according to a selected program for creating an effect simulative of a sound field in matching with a room situation under which the effector is installed, a program memory stores a plurality of programs which can be selected in terms of types of sound fields and types of room situations. A first switch is operated for designating a desired type of a sound field. A second switch is operated for designating a desired type of a room situation. One program is selected from the program memory according to both of the designated type of the sound field and the designated type of the room situation.

摘要： A howling prevention apparatus prevents a howling noise which is generated in a sound amplification system using a microphone and a loudspeaker. The howling prevention apparatus utilizes a plural number of first to n-th equalizers, which have a variable frequency response and which modulate an output of the microphone. A detector detects a frequency point at which a loop gain of the system reaches a peak while supplying a standard noise signal to the loudspeaker to produce a test sound and measuring the sound collected by the microphone through the series of the equalizers. A frequency response of the first equalizer is adjusted to suppress a noise peak at and around a frequency point detected by the detector. Then, a frequency response of the second equalizer is also adjusted to suppress a noise peak at and around another frequency point detected by the detector. Lastly, a frequency response of the n-th equalizer is adjusted by subsequently repeating the above setting procedure.

摘要： In an apparatus for amplifying a sound while suppressing a howling noise, a microphone collects a sound and converts the collected sound into a corresponding input signal. An amplifier amplifies the input signal to generate the sound through a loudspeaker. A plurality of equalizers are interposed between the microphone and the amplifier, each equalizer having a variable attenuation frequency for attenuatively filtering the input signal around the attenuation frequency. Detection is conducted for detecting a plurality of noise spectrum peaks of the howling noise contained in the collected sound. Then, an adjustment is conducted adjusting respective variable attenuation frequencies of the plurality of the equalizers correspondingly to the plurality of the detected noise spectrum peaks to thereby remove the howling noise from the generated sound.

摘要： A harmony chorus apparatus collects an original of a vocal sound performed after a main melody pattern of a song, and adds a chorus sound derived after a chorus melody pattern of the same song to the vocal sound. A memory stores a main melody data representative of the main melody pattern and a chorus melody data representative of the chorus melody pattern which is designed in harmony with the main melody pattern. A pitch difference calculator sequentially retrieves the main melody data and the chorus memory data from the memory in synchronization with progression of the song, and calculates a pitch difference between the main melody pattern and the chorus memory pattern according to the retrieved main melody data and chorus melody data. A chorus generator shifts a pitch of the collected vocal sound by the calculated pitch difference to generate the chorus sound in the form of a variation of the vocal sound. A mixing device mixes the generated variation of the vocal sound and the collected original of the vocal sound with each other to thereby create a harmony of the song.

摘要： A karaoke amplifier is constructed for amplifying an audio signal to sound a karaoke performance while processing the audio signal according to a value of a control parameter to acoustically control the karaoke performance. An analog operating member is manually operable to set an initial analog value of the control parameter. An analog/digital converter converts the initial analog value into a corresponding initial digital value. A receiver receives correction data from an external data source. A memory memorizes the received correction data. A calculator arithmetically treats the initial digital value according to the correction data retrieved from the memory to calculate a corrected value of the control parameter. A signal processor processes the audio signal according to the corrected value of the control parameter and amplifies the processed audio signal to sound the karaoke performance which is acoustically modified according to the corrected value of the control parameter.
