Bases: object

(experimental) Properties for AAC codec settings.

Parameters:

bitrate (Optional[Bitrate]) – (experimental) The average bitrate. Default: Bitrate.kbps(192)
coding_mode (Optional[AacCodingMode]) – (experimental) The coding mode (mono, stereo, 5.1). Default: AacCodingMode.CODING_MODE_2_0
input_type (Optional[AacInputType]) – (experimental) Set to broadcasterMixedAd when the input contains pre-mixed main audio + AD (narration) as a stereo pair. Default: AacInputType.NORMAL
profile (Optional[AacProfile]) – (experimental) The AAC profile. Default: AacProfile.LC
rate_control_mode (Optional[AacRateControlMode]) – (experimental) The rate control mode. Default: AacRateControlMode.CBR
raw_format (Optional[AacRawFormat]) – (experimental) Sets the LATM/LOAS AAC output for raw containers. Default: AacRawFormat.NONE
sample_rate (Optional[AudioSampleRate]) – (experimental) The sample rate. Default: AudioSampleRate.HZ_48000
spec (Optional[AacSpec]) – (experimental) The AAC specification (MPEG-4 or MPEG-2) used to encode the audio. Set to AacSpec.MPEG2 to emit MPEG-2 AAC instead of MPEG-4 AAC for raw or MPEG-2 Transport Stream containers. Default: AacSpec.MPEG4
vbr_quality (Optional[AacVbrQuality]) – (experimental) The VBR quality level. Used only if rateControlMode is VBR. Default: - service default
