Overview
Required when you set Codec to the value AAC. The service accepts one of two mutually exclusive groups of AAC settings–VBR and CBR. To select one of these modes, set the value of Bitrate control mode to “VBR” or “CBR”. In VBR mode, you control the audio quality with the setting VBR quality. In CBR mode, you use the setting Bitrate. Defaults and valid values depend on the rate control mode.

Instance Attribute Details
#audio_description_broadcaster_mix ⇒ String
Choose BROADCASTER_MIXED_AD when the input contains pre-mixed main audio + audio description (AD) as a stereo pair. The value for AudioType will be set to 3, which signals to downstream systems that this stream contains “broadcaster mixed AD”. Note that the input received by the encoder must contain pre-mixed audio; the encoder does not perform the mixing. When you choose BROADCASTER_MIXED_AD, the encoder ignores any values you provide in AudioType and FollowInputAudioType. Choose NORMAL when the input does not contain pre-mixed audio + audio description (AD). In this case, the encoder will use any values you provide for AudioType and FollowInputAudioType.

#bitrate ⇒ Integer
Specify the average bitrate in bits per second. The set of valid values for this setting is: 6000, 8000, 10000, 12000, 14000, 16000, 20000, 24000, 28000, 32000, 40000, 48000, 56000, 64000, 80000, 96000, 112000, 128000, 160000, 192000, 224000, 256000, 288000, 320000, 384000, 448000, 512000, 576000, 640000, 768000, 896000,

The value you set is also constrained by the values that
you choose for Profile, Bitrate control mode, and Sample rate. Default values depend on Bitrate control mode and Profile.

#codec_profile ⇒ String
Specify the AAC profile. For the widest player compatibility and where higher bitrates are acceptable: Keep the default profile, LC (AAC-LC) For improved audio performance at lower bitrates: Choose HEV1 or HEV2. HEV1 (AAC-HE v1) adds spectral band replication to improve speech audio at low bitrates. HEV2 (AAC-HE v2) adds parametric stereo, which optimizes for encoding stereo audio at very low bitrates.

#coding_mode ⇒ String
The Coding mode that you specify determines the number of audio channels and the audio channel layout metadata in your AAC output. Valid coding modes depend on the Rate control mode and Profile that you select. The following list shows the number of audio channels and channel layout for each coding mode. * 1.0 Audio Description (Receiver Mix): One channel, C. Includes audio description data from your stereo input. For more information see ETSI TS 101 154 Annex E.
-
1.0 Mono: One channel, C. * 2.0 Stereo: Two channels, L, R. *
5.1 Surround: Six channels, C, L, R, Ls, Rs, LFE.

#rate_control_mode ⇒ String
Specify the AAC rate control mode. For a constant bitrate: Choose CBR. Your AAC output bitrate will be equal to the value that you choose for Bitrate. For a variable bitrate: Choose VBR. Your AAC output bitrate will vary according to your audio content and the value that you choose for Bitrate quality.

#raw_format ⇒ String
Enables LATM/LOAS AAC output. Note that if you use LATM/LOAS AAC in an output, you must choose “No container” for the output container.
