Many DSP chips are required when we utilize the results of latest researches about sound field control for practical audio products. Therefore we have reduced the processing loads for equalizing acoustical transfer function by controlling only in low frequency and fixing FIR filter coefficients. In addition, we made difficult manual adjustments (setting step size parameters and delay timings) automatic. As a result, we produced the first consumer adaptive equalizer system for automobile which can equalize both frequency-gain response and group delay response. |
