        Description

        AU file format can contains the data in the float encoding. When support of AU was added to the jdk the float format was not supported. But in jdk 7 PCM_FLOAT was added(for WAV) and it can be reused for AU as well.

        In jdk9(JDK-8146239) support of "PCM_FLOAT and 32 sampleSizeInBits" was added. But AU format supports 64-bit as well:
