Phase spectrum content interface.
This purely abstract class defines the special interface for phase spectrum content (frequency-domain). Each record contains for each channel a fixed number of phase coefficients defined over a common support of frequencies.
The number and values of the support frequencies can be determined using the methods getNumFrequencies and getFrequencies. The phase coefficients can be retrieved using the method getPhases.

Retrieves phase coefficients.
This method retrives the phase coefficients for the given direction (record index) and channel and stores them in the supplied destination buffer. The method writes exactly as many coefficients as there are support frequencies. Their number can be determined using the method getNumFrequencies.
