way is to narrow the Microphone to Loudspeaker distance. The next figures, dealing

with Gating Effects, refer to a Microphone at 11.5cm (4.5") in front to a good

quality tweeter. FFT size is set to 512 points, the equivalent of about 10ms Meter

On at 48000Hz sampling rate. Fig.11.9 shows the effects of a wrong delay in

capturing a 2kHz 10ms tone burst. All harmonics are buried below the effects of

this wrong setting.

Figure 11.9

Fig.11.10 shows the effects of the device settling time as the delay is now correctly

set to 0.35ms. 40dB down the harmonics (1% distortion) should be visible now. As

the tweeter performs better than this what we see is the second harmonic canceling

the broad spectrum caused by the device settling time.
