Export Audio Configuration Data
Ansys Sound: ASDforEV enables you to export the audio output configuration data (speaker types and position, gains, equalizers).
- In the Audio configuration window, click the Export button .
- In the Browse for Folder window that opens, select the location where the data should be exported.
- 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.
