A general description of the XML file.

No attributes.

The node has the following child nodes, which are all optional. All of the nodes except comment are basically used for a transfer function file.

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

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

- TSPpath
A path to an audio file for transfer function measurement (TSP signal). A string is required.

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

- PeakSearch
This node have attributes:

`from`and`to`. This information is used for specifying the range of the peak detection of the direct sound for transfer function calculation. These attributes are mandatory, and must be natural numbers.- nfft
The length of Fourier transform for transfer function calculation. A natural number is required.

- samplingRate
The sampling rate of the recorded signals for transfer function measurement. A natural number is required, and usually we use 16000, i.e., 16kHz sampling.

- 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 sample. A natural number is required. Usually, we use 16384 samples.
