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]
