7.1.6 Generation of the TSP response list file

• The TSP response list file is a file showing the corresponding between TSP signal recording files and measurement locations.

• The file must be created according to the 5.3.1 Source position list information format (srcinf).

• the method to create this file using template generation function of HARKTOOL is as follows:

Figure 7.4: TSP ListFile generation screen (Setting1 tab)

Figure 7.5: TSP ListFile generation screen (Setting2 tab)

Generation process

1. Click the TSP button on the working space.

2. Input the parameters into the parameter input screen on the left side.
   

   Overview of setting items

   ■ Setting1

   • Spherical, Cylindrical
     Specify the coordinate system to use from the spherical coordinates or the Cylindrical coordinates.
     If the spherical coordinate system is chosen, the elevation can be entered. If the cylindrical coordinate system is chosen, the height can be entered.

   • Distance [m]
     The horizontal distance between the speaker and the microphone.

   • Elevation [deg]
     The elevation angle seen from the microphone in the direction of the speaker.
     From the starting height, each elevation (whose interval is specified in the next item) is added to the template.

   • Height [m]
     The height seen from the microphone in the direction of the speaker.
     From the starting height, each height (whose interval is specified in the next item) is added to the template.

   • Azimuth [deg]
     Ending angle (left), starting angle (right).
     From the starting angle, in the counterclockwise direction, each angle (whose interval is specified in the next item) is added to the template.

   • Template File Name
     The place/name of the TSP response recorded file (flt format).
     When the spherical coordinate is chosen, it contains the strings "{AZIMUTH:%03d}" and "{ELEVATION:%03d}" in the file name. When the cylindrical coordinate is chosen, it contains the strings "{AZIMUTH:%03d}" and "{ELEVATION:%03d}" in the file name. These strings are replaced to the correspond values.

   • Impulse File Name
     The filename of the TSP signal of one cycle used for recording.

   ■ Setting2

   • Synchronous Averaging
     The count of consecutive replays of TSP signal at the time of TSP signal recording

   • Length of one TSP
     The number of samples of TSP signal used for recording. Default setting need not be changed.

   • Max Value of Signal
     The value of the maximum amplitude. Default setting need not be changed.

   • Channel list
     The channel number to use. If you select the channel to use, check the box and specify the number in comma-delimited format. If you use all channels, the box need not be checked.

   • Cut Index [sample]
     The starting and ending positions of sample used for generating transfer functions.
     Default of the start position need not be changed.
     The ending position is used to ignore (delete) the reflection, for example, in the case of the refraction being louder than the direct sound.
     

3. Pushing the Create button on the bottom of the screen generates the TSP Response List File and displays the contents of the right side.
   

4. Pushing the bottom-right Plot button displays the graph according to the input parameters.

5. To save the created file use Save button on the bottom of the screen.
