AudioPackingMode
|
System.String |
Gets and sets the property AudioPackingMode.
The method of organizing audio channels and tracks. Use Audio:Channels to specify
the number of channels in your output, and Audio:AudioPackingMode to specify
the number of tracks and their relation to the channels. If you do not specify an
Audio:AudioPackingMode , Elastic Transcoder uses SingleTrack .
The following values are valid:
SingleTrack , OneChannelPerTrack , and OneChannelPerTrackWithMosTo8Tracks
When you specify SingleTrack , Elastic Transcoder creates a single track for
your output. The track can have up to eight channels. Use SingleTrack for all
non-mxf containers.
The outputs of SingleTrack for a specific channel value and inputs are as follows:
-
0 channels with any input: Audio omitted from the output
-
1, 2, or auto channels with no audio input: Audio omitted from the
output
-
1 channel with any input with audio: One track with one channel, downmixed
if necessary
-
2 channels with one track with one channel: One track with two identical
channels
-
2 or auto channels with two tracks with one channel each: One track
with two channels
-
2 or auto channels with one track with two channels: One track with
two channels
-
2 channels with one track with multiple channels: One track with two
channels
-
auto channels with one track with one channel: One track with one
channel
-
auto channels with one track with multiple channels: One track with
multiple channels
When you specify OneChannelPerTrack , Elastic Transcoder creates a new track
for every channel in your output. Your output can have up to eight single-channel
tracks.
The outputs of OneChannelPerTrack for a specific channel value and inputs are
as follows:
-
0 channels with any input: Audio omitted from the output
-
1, 2, or auto channels with no audio input: Audio omitted from the
output
-
1 channel with any input with audio: One track with one channel, downmixed
if necessary
-
2 channels with one track with one channel: Two tracks with one identical
channel each
-
2 or auto channels with two tracks with one channel each: Two tracks
with one channel each
-
2 or auto channels with one track with two channels: Two tracks with
one channel each
-
2 channels with one track with multiple channels: Two tracks with
one channel each
-
auto channels with one track with one channel: One track with one
channel
-
auto channels with one track with multiple channels: Up to eight tracks
with one channel each
When you specify OneChannelPerTrackWithMosTo8Tracks , Elastic Transcoder creates
eight single-channel tracks for your output. All tracks that do not contain audio
data from an input channel are MOS, or Mit Out Sound, tracks.
The outputs of OneChannelPerTrackWithMosTo8Tracks for a specific channel value
and inputs are as follows:
-
0 channels with any input: Audio omitted from the output
-
1, 2, or auto channels with no audio input: Audio omitted from the
output
-
1 channel with any input with audio: One track with one channel, downmixed
if necessary, plus six MOS tracks
-
2 channels with one track with one channel: Two tracks with one identical
channel each, plus six MOS tracks
-
2 or auto channels with two tracks with one channel each: Two tracks
with one channel each, plus six MOS tracks
-
2 or auto channels with one track with two channels: Two tracks with
one channel each, plus six MOS tracks
-
2 channels with one track with multiple channels: Two tracks with
one channel each, plus six MOS tracks
-
auto channels with one track with one channel: One track with one
channel, plus seven MOS tracks
-
auto channels with one track with multiple channels: Up to eight tracks
with one channel each, plus MOS tracks until there are eight tracks in all

Channels
|
System.String |
Gets and sets the property Channels.
The number of audio channels in the output file. The following values are valid:
auto , 0 , 1 , 2
One channel carries the information played by a single speaker. For example, a stereo
track with two channels sends one channel to the left speaker, and the other channel
to the right speaker. The output channels are organized into tracks. If you want Elastic
Transcoder to automatically detect the number of audio channels in the input file
and use that value for the output file, select auto .
The output of a specific channel value and inputs are as follows:
-
auto channel specified, with any input: Pass through up to eight input
channels.
-
0 channels specified, with any input: Audio omitted from the output.
-
1 channel specified, with at least one input channel: Mono sound.
-
2 channels specified, with any input: Two identical mono channels
or stereo. For more information about tracks, see Audio:AudioPackingMode.

Codec
|
System.String |
Gets and sets the property Codec.
The audio codec for the output file. Valid values include aac , flac ,
mp2 , mp3 , pcm , and vorbis .
|
|
CodecOptions
|
Amazon.ElasticTranscoder.Model.AudioCodecOptions |
Gets and sets the property CodecOptions.
If you specified AAC for Audio:Codec , this is the AAC compression
profile to use. Valid values include:
auto , AAC-LC , HE-AAC , HE-AACv2
If you specify auto , Elastic Transcoder chooses a profile based on the bit
rate of the output file.
|
|
SampleRate
|
System.String |
Gets and sets the property SampleRate.
The sample rate of the audio stream in the output file, in Hertz. Valid values include:
auto , 22050 , 32000 , 44100 , 48000 , 96000
If you specify auto , Elastic Transcoder automatically detects the sample rate.
