5.1.2 config

5.1.2.1 What is this node for?

It contains the general description of the XML file.

5.1.2.2 Attributes

No attributes.

5.1.2.3 Child Elements

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.
