+ * decoding. The presence of an ASPI frame requires the existence of a
+ * {@link Zend_Media_Id3_Frame_Tlen TLEN} frame, indicating the duration of the

+ * The <i>Group identification registration</i> frame enables grouping of
+ * otherwise unrelated frames. This can be used when some frames are to be
+ * signed. To identify which frames belongs to a set of frames a group
+ * identifier must be registered in the tag with this frame.
+ *
+ * The owner identifier is a URL containing an email address, or a link to a
+ * location where an email address can be found, that belongs to the
+ * organisation responsible for this grouping. Questions regarding the grouping
+ * should be sent to the indicated email address.
+ *
+ * The group symbol contains a value that associates the frame with this group
+ * throughout the whole tag, in the range 0x80-0xf0. All other values are
+ * reserved. The group symbol may optionally be followed by some group specific
+ * data, e.g. a digital signature. There may be several GRID frames in a tag
+ * but only one containing the same symbol and only one containing the same
+ * owner identifier. The group symbol must be used somewhere in the tag. See
+ * {@link Zend_Media_Id3_Frame#GROUPING_IDENTITY} for more information.

+ * To increase performance and accuracy of jumps within a MPEG audio file,
+ * frames with time codes in different locations in the file might be useful.
+ * The <i>MPEG location lookup table</i> frame includes references that the
+ * software can use to calculate positions in the file.
+ *
+ * The MPEG frames between reference describes how much the frame counter should
+ * be increased for every reference. If this value is two then the first
+ * reference points out the second frame, the 2nd reference the 4th frame, the
+ * 3rd reference the 6th frame etc. In a similar way the bytes between reference
+ * and milliseconds between reference points out bytes and milliseconds
+ * respectively.
+ *
+ * Each reference consists of two parts; a certain number of bits that describes
+ * the difference between what is said in bytes between reference and the
+ * reality and a certain number of bits that describes the difference between
+ * what is said in milliseconds between reference and the reality.
+ *
+ * There may only be one MLLT frame in each tag.

+ * server using the <i>Recommended buffer size</i> frame. If the embedded info
+ * flag is set then this indicates that an ID3 tag with the maximum size
+ * described in buffer size may occur in the audio stream. In such case the tag
+ * should reside between two MPEG frames, if the audio is MPEG encoded. If the
+ * position of the next tag is known, offset to next tag may be used. The offset
+ * is calculated from the end of tag in which this frame resides to the first
+ * byte of the header in the next. This field may be omitted. Embedded tags are
+ * generally not recommended since this could render unpredictable behaviour
+ * from present software/hardware.
+ *
+ * For applications like streaming audio it might be an idea to embed tags into
+ * the audio stream though. If the clients connects to individual connections
+ * like HTTP and there is a possibility to begin every transmission with a tag,
+ * then this tag should include a recommended buffer size frame. If the client
+ * is connected to a arbitrary point in the stream, such as radio or multicast,

+ * The <i>Reverb</i> is yet another subjective frame, with which you can adjust

+ * the amount of volume that should be returned to the next echo bounce. $00 is
+ * 0%, $FF is 100%. If this value were $7F, there would be 50% volume reduction
+ * on the first bounce, 50% of that on the second and so on. Left to left means
+ * the sound from the left bounce to be played in the left speaker, while left
+ * to right means sound from the left bounce to be played in the right speaker.
+ *
+ * Premix left to right is the amount of left sound to be mixed in the right
+ * before any reverb is applied, where $00 id 0% and $FF is 100%. Premix right

+ * The tempo data consists of one or more tempo codes. Each tempo code consists

+ * or two bytes. If the first byte has the value $FF, one more byte follows,
+ * which is added to the first giving a range from 2 - 510 BPM, since $00 and
+ * $01 is reserved. $00 is used to describe a beat-free time period, which is
+ * not the same as a music-free time period. $01 is used to indicate one single
+ * beat-stroke followed by a beat-free period.
+ *
+ * The tempo descriptor is followed by a time stamp. Every time the tempo in the
+ * music changes, a tempo descriptor may indicate this for the player. All tempo
+ * descriptors must be sorted in chronological order. The first beat-stroke in
+ * a time-period is at the same time as the beat description occurs. There may
