AudioEncoding
is an option for Export and other functions that specifies the audio encoding to use when creating an audio or a video file.
Details
- AudioEncoding can be set to any available encoder listed in $AudioEncoders.
Examples

By default, the audio codec used to generate a file is automatically chosen:
v = Video["http://exampledata.wolfram.com/office.ts"];
Export["file.mkv", v];
Import["file.mkv", "AudioEncoding"]Check for available audio codecs supported for a format:
$AudioEncoders["Matroska"][[All, 1]]Export["file.mkv", v, AudioEncoding -> "LIBMP3LAME"];
Import["file.mkv", "AudioEncoding"]Scope (2)
Specify an audio encoding for video generation:
VideoGenerator[<|"Image" -> RandomImage[], "Audio" -> AudioGenerator["White"]|>, AudioEncoding -> "FLAC"]Information[%, "AudioTracks"]By default, the audio encoding is automatically chosen depending on the input data to minimize use of resources:
v = VideoCombine[{Video["ExampleData/bullfinch.mkv"], ExampleData[{"Audio", "PianoScale"}]}];
Information[v, "AudioTracks"]Using a specific encoder will force all audio tracks to be re-encoded:
v = VideoCombine[{Video["ExampleData/bullfinch.mkv"], ExampleData[{"Audio", "PianoScale"}]}, AudioEncoding -> "FLAC"];
Information[v, "AudioTracks"]Text
