Smarter response to Sample reading and writing working around the
JavaSound 24-bit limitation. Reading and writing those files should now
generally work out of the box. 2 caveats: i) Some wavs work and others
don't. Those that don't were distinct in that they are described in
Quicktime as "stereo" rather than "2 channel". Haven't looked into what
this means yet. ii) writing at a sample rate different from the
AudioContext sample rate pitches the sound in the current form. Since
there is no loss of data and the sample can be converted by other tools
this is not considered an important deficiency.
