るグラフイツクイコライザ。 A magnetic recording/reproducing means for recording on a magnetic medium or reproducing recorded contents on the magnetic medium, a level control means for controlling the level of reproduction output by the magnetic recording/reproducing means over an arbitrary frequency band, and the level control means. a detection means for outputting a filtered detection signal for each of the band-pass filtering means, a pink noise generation means, and a pink noise generation means for detecting the pink noise from the pink noise generation means. a control means for controlling whether or not to supply the pink noise to the magnetic recording and reproducing means; and a detecting means for reproducing the recorded content as the reproduction output when the pink noise is supplied to the magnetic recording and reproducing device and being recorded. 1. A graphical equalizer comprising: calculation means for determining a recording/reproducing level over the entire frequency band based on a filtered detection signal in each frequency band.
