Comment (by Kamedo2):

 I checked the document (fdk-aac-0.1.2/documentation/aacEncoder.pdf), and
 it said:
 > 3.3 Encoder Tools
 > The AAC encoder supports TNS, PNS, '''MS, Intensity''' and activates
 these tools depending on the audio signal and the encoder configuration
 (i.e. bitrate or AOT). It is not required to configure these tools
 manually.
