- Pre-Impulse Response Window
- This menu offers a selection of window types to be applied to the
data before the impulse peak. The default is a rectangular window.
- Post-Impulse Response Window
- This menu offers a selection of window types to be applied to the
data after the impulse peak. The default is a Tukey window.
- Low Frequency Decay Window
- This menu offers a selection of window types to be applied to the
data when generating the spectral decay and waterfall plots. The default
is a Blackman-Harris window.
- Low Frequency Decay Window Posn
- This menu selects whether the window used for low frequency decay
calculations should be initially centred on the impulse response peak
or offset to the right, so that the initial peak is excluded from all
slices except the first. Using "Centred" gives a smoother decay plot,
more like those produced by ETF, but makes the rate of decay appear
slower than it actually is. The offset window makes slowly decaying room
modes stamd out more prominently. The default is to use an offset
window, the choice is remembered for the next startup.
- Delete Data for Current Channel
- Delete all the measurement data for the current channel. Data cannot be
recovered!
- Apply 1/3 octave smoothing to current channel Ctrl+Shift+3
- Apply a one-third octave smoothing filter to the current channel.
Equivalent to selecting 1/3 in the trace smoothing box in the Filter Adjustment
graph group.
