Hi, Alex.
Thanks for review.
We have the same issue in most of our readers and writers(for ex
WaveFileWriter.java:198). In general our code in lots of place works
incorrectly when we convert unsigned integer to long/int and back.
I'll fix it in: https://bugs.openjdk.java.net/browse/JDK-6729836

Hi Sergey,
Overall looks good, but could you please fix possible int overflow in
AuFileWriter.java:
165 int fileSize;
166 if (stream.getFrameLength() != AudioSystem.NOT_SPECIFIED) {
167 fileSize =
(int)stream.getFrameLength()*streamFormat.getFrameSize() +
AuFileFormat.AU_HEADERSIZE;
168 } else {
169 fileSize = AudioSystem.NOT_SPECIFIED;
170 }
171
172 return new AuFileFormat(Type.AU, fileSize, format,
173 (int) stream.getFrameLength());

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
