Figure 71. Audio Performance Measurement System
The system performance was measured for three filter types at 48 kHz.
Butterworth high-pass filter at 1 kHz
Butterworth low-pass filter at 1 kHz
EQ filter at 1 kHz with a gain of 8 dB and a bandwidth of 500 Hz
The audio performance that was measured is shown in Table 71. The response shapes of the three test filters are
shown in Figure 72.
