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.

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.
