The audio
module reads mono or stereo media data from a file or stream, and can pass the data to other modules for further processing.
Mode | Input | Output | Description |
---|---|---|---|
MONO
|
a , ts |
Reads a mono media file, data block, or stream. | |
STEREO
|
l , r , ts |
Reads a stereo media file, data block, or stream. | |
MONO_WRITE
|
a
|
Writes a mono media file, data block, or stream. |
The ts
output is optional. This output stream provides additional time-shift information, such as offsets in the audio data because of the StartTime
parameter, or missing frames.
Examples:
a, ts <- audio(MONO, input)
l, r, ts <- audio(STEREO, input)
Some of these parameters do not have an internal default value. You must either set the configuration parameter to a suitable value, or set the value in the corresponding action parameter.
If you do not set the File parameter, you must set InputType. You can submit binary audio data (POST/Multipart), in which case the server uses the binary data block as the audio data source, or you can use an audio stream.
