Publication number: 20120099741Abstract: An acoustic signal's high frequency component extracted by an HPF 13 is multiplied in a multiplier 16 by the first coefficient to control the level of the high frequency component. The first coefficient is generated by a coefficient generation portion 21 in accordance with the full band level of an output signal. A low frequency component extracted by an LPF 15 is multiplied in a multiplier 17 by the second coefficient to control the level of the low frequency component. The second coefficient is generated by a coefficient generation portion 24 in accordance with the level of the output signal's low frequency component extracted by an LP filter 22. The level control of the low frequency component of the output signal and the level control of the high frequency component of the output signal are done separately, resulting in the loudness control which is suitable for the characteristic of the acoustic signal.Type: ApplicationFiled: October 19, 2011Publication date: April 26, 2012Applicant: Yamaha CorporationInventors: Mitsutaka GOTOH, Mizuyuki SHIRAI, Yuji YAMASHITA
