Hello, Audio Guru.
Please review the small fix for jdk9.
According to specification [1] AU file format can contains the data in
the float encoding. When support of AU was added to the jdk the float
encoding was not supported. But in jdk 7 PCM_FLOAT was added(for WAV)
and it can be reused for AU as well.
Changes description:
1) AuFileFormat.java/AuFileReader.java: the pcm_float was added to the
switches.
2) AuFileWriter.java:
- The "if" statement in getAudioFileFormat() was reworked. Its
purpose was to change the type PCM_UNSIGNED to PCM_SIGNED(because au
support only signed pcm). But it was written in some strange manner.
Note that this method returns the type which should be used in the saved
audio file.
- In the getFileStream() I removed the checks and always converts
the input stream to the AudioFileFormat which was returned from the
getAudioFileFormat() and the AudioSystem.getAudioInputStream() will
recognize conversion is needed or not
