Description
The AAC encoder processing component lets you encode audio in
AAC-LC, AAC-HE v1 and AAC-HE v2 format. It generates a raw audio
stream.
Figure 3-290. AAC-encoder parameters
Parameters
For this processing component, you must set the following parameters:
 AAC type : choose the format from the list: AAC-LC , AAC-HE v1
(SBR) , AAC-HE v2 (SBR+PS) .
For AAC-HE v1 (SBR) and AAC-HE v2 (SBR+PS) types, also set the
following parameter:
 Signaling mode : choose the mode from the list:
- Implicit and Explicit backward : a player that supports only
AAC-LC will be able to decode the AAC-LC part of the
stream.
- Explicit hierarchical : the stream cannot be decoded by a
player that supports only AAC-LC. This ensures that
listeners will get the full audio quality.

Bitrate : enter the bitrate of the audio stream, in bits per second.
