+/* Some things to note about the RMS window length of the analysis
+ * algorithm and thus the implementation used in the element:
+ * Processing divides input data into 50ms windows at some point.
+ * Some details about this that normally do not matter:
+ *
+ * 1. At the end of a stream, the remainder of data that did not fill
+ * up the last 50ms window is simply discarded.
+ *
+ * 2. If the sample rate changes during a stream, the currently
+ * running window is discarded and the equal loudness filter gets
+ * reset as if a new stream started.
+ *
+ * 3. For the album gain, it is not entirely correct to think of
+ * obtaining it like "as if all the tracks are analyzed as one
+ * track". There isn't a separate window being tracked for album
+ * processing, so at stream (track) end, the remaining unfilled
+ * window does not contribute to the album gain either.
+ *
+ * 4. If a waveform with a result gain G is concatenated to itself
+ * and the result processed as a track, the gain can be different
+ * from G if and only if the duration of the original waveform is
+ * not an integer multiple of 50ms. If the original waveform gets
+ * processed as a single track and then the same data again as a
+ * subsequent track, the album result gain will always match G
+ * (this is implied by 3.).
+ *
+ * 5. A stream shorter than 50ms cannot be analyzed. At 8000 and
+ * 48000 Hz, this corresponds to 400 resp. 2400 frames. If a
+ * stream is shorter than 50ms, the element will not generate tags
+ * at EOS (only if an album finished, but only album tags are
+ * generated then). This is not an erroneous condition, the
+ * element should behave normally.
+ *
+ * The limitations outlined in 1.-4. do not apply to the peak values.
+ * Every single sample is accounted for when looking for the peak.
+ * Thus the album peak is guaranteed to be the maximum value of all
+ * track peaks.
+ *
+ * In normal day-to-day use, these little facts are unlikely to be
+ * relevant, but they have to be kept in mind for writing the tests
+ * here.
