class Aws::MediaConvert::Types::AacSettings

Required when you set (Codec) under (AudioDescriptions)>(CodecSettings) 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 (rateControlMode) to “VBR” or “CBR”. In VBR mode, you control the audio quality with the setting VBR quality (vbrQuality). In CBR mode, you use the setting Bitrate (bitrate). Defaults and valid values depend on the rate control mode.

@note When making an API call, you may pass AacSettings

data as a hash:

    {
      audio_description_broadcaster_mix: "BROADCASTER_MIXED_AD", # accepts BROADCASTER_MIXED_AD, NORMAL
      bitrate: 1,
      codec_profile: "LC", # accepts LC, HEV1, HEV2
      coding_mode: "AD_RECEIVER_MIX", # accepts AD_RECEIVER_MIX, CODING_MODE_1_0, CODING_MODE_1_1, CODING_MODE_2_0, CODING_MODE_5_1
      rate_control_mode: "CBR", # accepts CBR, VBR
      raw_format: "LATM_LOAS", # accepts LATM_LOAS, NONE
      sample_rate: 1,
      specification: "MPEG2", # accepts MPEG2, MPEG4
      vbr_quality: "LOW", # accepts LOW, MEDIUM_LOW, MEDIUM_HIGH, HIGH
    }

@!attribute [rw] audio_description_broadcaster_mix

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.
@return [String]

@!attribute [rw] bitrate

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,
1024000. The value you set is also constrained by the values that
you choose for Profile (codecProfile), Bitrate control mode
(codingMode), and Sample rate (sampleRate). Default values depend on
Bitrate control mode and Profile.
@return [Integer]

@!attribute [rw] codec_profile

AAC Profile.
@return [String]

@!attribute [rw] coding_mode

Mono (Audio Description), Mono, Stereo, or 5.1 channel layout. Valid
values depend on rate control mode and profile. "1.0 - Audio
Description (Receiver Mix)" setting receives a stereo description
plus control track and emits a mono AAC encode of the description
track, with control data emitted in the PES header as per ETSI TS
101 154 Annex E.
@return [String]

@!attribute [rw] rate_control_mode

Rate Control Mode.
@return [String]

@!attribute [rw] raw_format

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.
@return [String]

@!attribute [rw] sample_rate

Sample rate in Hz. Valid values depend on rate control mode and
profile.
@return [Integer]

@!attribute [rw] specification

Use MPEG-2 AAC instead of MPEG-4 AAC audio for raw or MPEG-2
Transport Stream containers.
@return [String]

@!attribute [rw] vbr_quality

VBR Quality Level - Only used if rate\_control\_mode is VBR.
@return [String]
