It contains the general description of the XML file.

No attributes.

config has the following optional child elements. All except "comment" are used for transfer function file.

- comment
A description of the file. Any string is acceptable.

- SynchronousAverage
The number of repetition of a signal used for transfer function measurement (TSP signal). A natural number is required.

- TSPpath
The path of the audio file for transfer function measurement (TSP signal). A string is required.

- TSPOffset
An offset during transfer function calculation. A natural number is required.

- PeakSearch
It has the attributes

`from`and`to`. It is used to specify the range when searching for the peak of the direct sound during transfer function calculation. These attributes are mandatory and must be natural numbers.- nfft
The length of Fourier transform during transfer function calculation. A natural number is required.

- samplingRate
The sampling frequency of the recorded signal for transfer function measurement. A natural number is required. The initial sampling rate is 16kHz.

- signalMax
The maximum amplitude of the recorded signal for transfer function measurement. A natural number is required. If the wave file’s sample width is 16bit, the value must be 32767.

- TSPLength
The length of a signal for transfer function measurement (TSP signal) in a sample. A natural number is required. The initial value is 16384 samples.
