Export Audio Configuration Data

Ansys Sound: ASDforEV enables you to export the audio output configuration data (speaker types and position, gains, equalizers).

Prerequisites: Multichannel mode must be selected. See Audio Output Modes.
  1. In the Audio configuration window, click the Export button .
  2. In the Browse for Folder window that opens, select the location where the data should be exported.
  3. Click OK.

All audio output configuration data is exported in an AudioConfigurationData folder that is created at the location you selected. Each speaker is exported as a distinct text file that also contains equalizer data. The 4 first lines indicate the speaker name, type and polar coordinates. The rest of the file specifies the equalizer used, in the form of 8 biquad filters, whose activation states (bypassed), types, frequencies, gains, Q-factors and corresponding biquad coefficients are specified. The biquad coefficients are the 5 coefficients b0 , b1 , b1 , a1 , and a2 that correspond to the following filter transfer function:

Example:

   Name: AVAS
   Type: System
   Angle (°): 23
   Distance (m): 1.430
   Gain (dB): 0.000
    
   Filter1:
   Bypassed (0/1): 0
   Type: lowpass
   Frequency (Hz): 2000.000
   Gain (dB): 0.000
   Q: 1.000
   Biquad coefficients (b0 b1 b2 a1 a2): 0.018 0.035 0.018 -1.683 0.754
    
   Filter2:
   Bypassed (0/1): 0
   Type: highpass
   Frequency (Hz): 200.000
   Gain (dB): 0.000
   Q: 1.000
   Biquad coefficients (b0 b1 b2 a1 a2): 0.986 -1.972 0.986 -1.971 0.972
    …

A summary file Summary_report.txt is also stored and summarizes the number of speakers of each type and the total number of biquad filters necessary.
