  • Publication number: 20040146170
    Abstract: A graphic audio equalizer alters an audio frequency response in selected frequency bands using a plurality of filters of variable level, fixed frequency band and fixed center-frequency frequency. A circuit simulates the operation of a parametric audio equalizer to alter an audio frequency response in the shape of at least one bell curve defined by center frequency, Q-factor and maximum level, the following functions being implemented in the circuit: selection of one of the fixed frequency bands as the center frequency, selection of further fixed frequency bands on both sides of the fixed frequency band which determines the center frequency in order to stipulate the Q-factor, and adjustment of the levels of the further fixed frequency bands on the basis of the maximum level of the fixed frequency band which determines the center frequency in line with the shape of the bell curve.

  • Publication number: 20030223596
    Abstract: An audio multi-channel equalizer having a plurality of bandpass filters for subdividing an audio signal into a plurality of channels. The equalizer also includes level controllers associated with the channels and optical level-indicating means. The optical level indicating means contains semiconductor switches connected to the outputs of the bandpass filters for activation of optical indications. There is also a reference voltage generator which corresponds substantially to the average signal level of the channels and which is connected commonly to all semiconductor switches.
