Audio
Use Audio
Selects whether the target will contain an audio track.
Use Always
The target will always contain an audio track, even if the source
does not contain audio.
Use if Exist
The target will contain an audio track if the source contains audio. If
the source does not contain audio, the target will not have an audio
track.
Don’t Use
The target will not have an audio track, even if the source contains
audio.
Channels
Sets the number of channels and if applicable, the channel type for the audio output.
Common options are:
Stereo
Two channels of audio (left/right).
Mono
One channel of audio.
Sample Rate(kHz)
Sets the sampling rate or number of samples per second, of the audio in thousands
of samples per second. The reproducible frequency range of encoded audio depends
on the sample rate.
Bits / Sample
Sets the audio sample size in bits per sample. The more bits per sample, the better
the representation of changes in the audio level and hence the better the audio
quality. The combination of sample rate and bits per sample determine the overall
quality of the audio.
Audio Bitrate (kbps)
For non-fixed bitrate codecs, sets the audio bitrate in kilobits-per-second. Generally,
the higher the bitrate, the better the audio quality is.
Audio Codec
Selects the audio codec used to decode the source audio.
Notes
Not all targets will include all of the common parameters. Some parameters are
available only in certain cases.
