short empty in the begin of aac data

Dear Experts,

Platform:DM8148 custome board/DVR RDK3.5

We encoded pcm audio to aac (adts).
Compare the raw pcm and encoded aac as show in below figure.
audio: the encoded aac waveform
test: the input raw pcm

Image may be NSFW.
Clik here to view.


There are around 12 msec empty (mute) in the begin of aac data, is this resonable ??

This will cause AV unsync.
