Spectrum as a txt File
This section describes the spectrum as a txt file used for the sound creation.
To create a sound, Sound: Analysis and Specification needs two inputs.
First input is the txt file which contains the spectrum (dB SPL vs frequency).
Second input is the type of the method used for the sound creation. Two methods are available in Sound: Analysis and Specification for this purpose.
The txt file loading is done from

Text file description
The text file which contains the spectral data is formatted as follows:
1st line: AnsysSound_Spectrum X.
where X is the version number. The current version is 1.
1st column: frequency in Hz
2nd column: Sound Pressure Level, in dB SPL
Each column is separated by space or tabulation.
Example:

The sound generated as output is stationary and exhibits the same spectrum as the input spectrum. The created sound signal is stationary.
