Figure 10.6: This file contains the same impulse three times in a row. The second version used a linear phase equalizer to apply 18 dB of boost at 300 Hz with a Q of 6, and the third is the same impulse but EQ’d with a Q of 20.

Figure 10.7: Zooming in to see the wave cycles more clearly shows that a linear phase EQ adds ringing both after and before the impulse.

When you play the example file in Figure 10.6, you’ll hear that it sounds very different from the version in Chapter 3 that applied conventional minimum phase EQ. To my ears, this version sounds more affected, and not in a good way. Nor is there much difference in the waveform—both visually and audibly—whether the Q is set to 6 or 20.
