+ * Audio files with variable bit rates are intrinsically difficult to deal with
+ * in the case of seeking within the file. The <i>Audio seek point index</i> or
+ * ASPI frame makes seeking easier by providing a list a seek points within the
+ * audio file. The seek points are a fractional offset within the audio data,
+ * providing a starting point from which to find an appropriate point to start
+ * decoding. The presence of an ASPI frame requires the existence of a
+ * {@link ID3_Frame_TLEN} frame, indicating the duration of the file in
+ * milliseconds. There may only be one audio seek point index frame in a tag.
