The /audio/loop Robot

We offer a variety of features to reduce audio size while maintaining quality, as well as add effects like loops or watermarks.

Wether you're producing beats, white-noise, or just empty segments as fillers between audio tracks that you're to stringing together with our /audio/concat Robot, /audio/loop has got you're back.

Parameters

Name	Type	Default	Description
`preset`	String	`"mp3"`	Performs conversion using pre-configured settings. If you specify your own FFmpeg parameters using the Robot's `ffmpeg` parameter and you have not specified a preset, then the default `mp3` preset is not applied. This is to prevent you from having to override each of the `mp3` preset's values manually. For a list of audio presets, see audio presets.
`bitrate`	Integer	Auto	Bit rate of the resulting audio file, in bits per second. If not specified will default to the bit rate of the input audio file
`sample_rate`	Integer	Auto	Sample rate of the resulting audio file, in Hertz. If not specified will default to the sample rate of the input audio file
`duration`	Float	`60.0`	Target duration for the whole process in seconds. The Robot will loop the input audio file for as long as this target duration is not reached yet.
