/audio/encode robot

Takes a single audio file and converts it to a given format.

Optional parameters

Name	Type	Default	Description
use	String or array	The previous step	Specifies which step to use as the input to this robot. The default is to use the previous step defined above the current one. A special step name is `":original"`, which "uses" the originally uploaded files. You can also add arrays here to "use" several steps: `"use": [":original", "encode2", "resizing3"]` See a demo for the "use" parameter here.
bitrate	integer	Bit rate of the input audio file	Bit rate for the resulting audio file in bit/s.
preset	string	`""`	Converts using pre-configured settings. Please click here for a list of presets.
sample_rate	integer	Sample rate of the input audio file	Sample rate for the resulting audio file in Hz.
ffmpeg	object	`{}`	An object with parameters to pass to FFmpeg. Check the FFmpeg documentation for available options. If you are using a preset, the options given here will be merged on top.
force_accept	boolean	`false`	Robots may accept only certain file types - all other possible input files are ignored. This means the `/video/encode` robot for example will never touch an image while the `/image/resize` robot will never look at a video. With the `force_accept` parameter you can force a robot to accept all files thrown at him, regardless if it would normally accept it.
