I encode monophonic sampled sounds in Sun audio (.au) file format. Sun audio files have a very simple format but can store both compressed and uncompressed sample data. I can write this format either directly into a file or onto any writable binary stream.

	setStream: Initialize myself for writing on the given stream.

	other	top
	appendBytes: Append the given sample data to my stream.
	appendSamples: Append the given SoundBuffer to my stream.
	closeFile Update the Sun audio file header to reflect the final size of the sound data. If my stream is a file stream, close it and, on a Macintosh, set the file type and creator to that used by SoundApp for Sun Audio files. (This does nothing on other platforms.)
	ensureOpen Ensure that my stream is open.
	updateHeaderDataSize Update the Sun audio file header to reflect the final size of the sound data.
	writeHeaderSamplingRate: Write a Sun audio file header for 16-bit linear format.
	writeHeaderSamplingRate:format: Write a Sun audio file header for the given sampling rate and format. Currently, only monophonic files are supported.

	codecForFormatCode: Answer the codec for the given Sun audio file format number.
	formatCodeForCompressionType: Answer the Sun audio file format number for the given compression type name.
	storeSound:onFileNamed:compressionType: Store the samples of the given sampled sound on a file with the given name using the given type of compression. See formatCodeForCompressionType: for the list of compression types.
