Any implementations supporting the Ogg Vorbis extension keep the data in
Ogg Vorbis format internally and decompress small chunks of it on the
fly -- to save memory... In some cases, there may be an optimization
where small Ogg Vorbis buffers are decompressed only once, but that
would only be for truly small buffers.
