I have never used AudioInputStream. If that one reports the real size when calling available() then it would be the
firstInputStream that I have seen that does that ;)
If you do use available() you should verify that the size of your BLOB (bytea) in the database is really what you
expected.You have to test with sizes that exceed any potential buffer that takes place in the input stream, and I would
inspectthe source code for available().
