-/* 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.

- * Even if we would generate a wave describing a signal with the same frequency
