AAC output reference tables

This topic covers AAC audio codec support and lists the supported combinations of coding mode, profile, sampling rate, and bitrate.

This section explains how to set the following four properties of the AAC audio codec:

  • Profile

  • Coding mode

  • Sample rate

  • Bitrate

The settings that you choose for Profile, Coding mode, Sample rate, and Bitrate are limited by the AAC codec. The following procedure shows how to configure a supported combination of settings.

Choosing AAC audio codec settings
  1. Choose a Profile.

  2. Choose a Coding mode that is valid with that profile. The Coding mode determines the number of audio channels and the audio channel layout metadata.

  3. Choose a Sample rate that is valid for that combination of profile and coding mode.

  4. Choose a Bitrate that falls within the range that is supported for that sample rate.

CBR Bitrate control mode

AWS Elemental MediaConvert supports the following combinations of AAC settings when your output Bitrate control mode is CBR.

To use this table, choose a profile from the Profile column. Then read across to find a valid combination of Coding mode, Sample rate, and Bitrate:

Profile Coding mode(s) Sample rate(s) (Hz) Bitrate(s) (bit/s)
