7.1.7 Generation of the microphone location information file

• The microphone location information file is a text file describing the microphone locations.

• This file must be created according to the Microphone position text format.

• The microphone location information file is necessary to generate transfer function files used for the LocalizatioonMUSIC module or GHDSS module.

• The method to create this file using template generation function

Generation Process

1. Click the MICARRAY button on the working screen.

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

   Overview of setting items

   • 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 center of the microphone array and each microphone.

   • Elevation [deg]
     Input the start, end, and interval elevation angles of the center of the microphone array and microphone.

   • Height [m]
     Input the start, end, and interval heights seen from the microphone in the direction of the center of the microphone array.

   • Azimuth [deg]
     Ending angle (left), starting angle(right). Input the starting, ending, and interval angles. These values are added to the template at every interval (specified in the next item), from the starting angle, in the counterclockwise direction.

   • Channel List
     A list fo channel number to use. If you want to select the channels instead of using all channels, check the box on the input box and specify the numbers in comma-delimited format. If you want to use all channels, check off the box. The channel list must be the same as one specified in corresponding impulse response list file or TSP response list file.

3. Pushing the Create button on the bottom of the screen generates the microphone location information 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.
