There are two modes for audio recording, lock mode and unlock mode. In lock mode,
the sampling frequencies of audio and video are synchronized. In unlock mode,
which consumer DV format adopts, the two sampling frequencies are independent.
Therefore, lock mode is more effective than unlock mode in digital processing and
smooth transition during audio editing.
