Speech frame of AMR

A speech frame represents one frame encoded with the mode according to the ToC field FT. The length of this field is implicitly defined by the mode in the FT field. The bits SHALL be sorted according to Annex B of [2] for AMR and Annex B of [4] for AMR-WB.

If octet aligned operation is used, the last octet of each speech frame MUST be padded with zeroes at the end if not all bits are used.
