10.2.1 TOOLBAR BUTTONS Starts an MLS measurement. If pressed the measurements will be autosaved. The current autosave definitions apply; see 6.3.1 for details. Selects the Loop mode. When in Loop mode the MLS measurement is automatically repeated until the users presses a keystroke or releases the button. If Autosave is active the loop mode ends after the total files to be autosaved are done. When an MLS measurement is taken, automatically applies the selected postprocess. Enters the MLS Process dialog box. Enters the MLS settings dialog box. Enters Time domain. Enters Frequency domain. Displays phase. Displays group delay. 10.2.2 TOOLBAR DROP DOWN LISTS input channel Selects the input channel configuration. Y scale unit Selects the measurement units. It is possible to select Voltage (dBV, dBu, dBRel) or Pressure (dBSPL) or Impedance (Ohm). smoothing Activates a frequency smoothing of the active curve. This smoothing effect will allow for a better appreciation of the general features of the response curve. The smoothing algorithm that is employed averages all values within a fraction-of-octave band surrounding each analysis frequency. 86 Chapter 10 - MLS
10.2.3 MLS SETTINGS DIALOG Figure 10.2 sampling Selects the measurement sampling frequency. size Selects the size of the MLS sequence. window Selects the appropriate kind of window for analyzing time data. It is possible to select between a rectangular, Hanning or Blackman window; the last two can be full or half sized. NOTE: These windows are applied to the time portion to be transformed with FFT. If the start point is near the impulse full windows will null the most important part of the time response (due to their rise time). To evaluate the effetcs of a data window refer also to Chapter 9, and FFT measurements in general. stimuli Selects the kind of stimulus used for the measurement of the impulse response. averages Controls the averaging mode of operation. The measurement will be repeated and averaged the number of times set, therefore obtaining a better signal-to-noise ratio at the expense of reduced measurement speed. Continuous performs the number of averages in the shortest time without waiting. <strong>Manual</strong> waits the user to press any key between each measure; it is useful, for example, in averaging different microphone positions. phase & group delay Used to select how phase (group delay) response is obtained. Normal displays the measured phase (group delay) curve referring to the selected time domain data. Minimum calculates and displays the phase (group delay) curve, related to the current modulus curve, in the assumption of minimum phase behaviour (i.e. the Hilbert transform of the log magnitude). Excess calculates and displays the phase (group delay) curve as the difference between the Normal and the Minimum ones. It is possible to display phase data wrapped at ±180 degrees boundaries or unwrapped. impedance When taking impedance measurement refers either to the internal impedance mode or to the ISense feature of the CLIOQC Amplifier&SwitchBox Model 2 and 3.
