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 |
---|---|---|---|
use
|
(required) String / Array of Strings | GeneralSpecifies which Step(s) to use as the input to this Robot.Special Step namesA special Step name is":original" , which provides user uploads handled by Transloadit.
Providing several Steps as inputYou can add arrays touse several Steps:
Step bundlingSome Robots can gather several Step results for a single invocation. For example, the /file/compress Robot would normally create one Zip file for each file passed to it. If you'd setbundle_steps to true,
however, it will create one archive containing all the result files from
all Steps you give it. To enable bundling, provide an object
like the one below to the use parameter:
This is a crucial parameter
for the /video/adaptive Robot,
otherwise you'll generate 1 playlist for each viewing quality. Keep in mind that all input Steps must be present in your Template. If one of them is missing, no result is generated because the Robot waits indefinitely for all input Steps to be finished. Group by originalSticking with the /file/compress Robot example, you can setgroup_by_original to true , in order to create a separate Zip file
for each of your uploaded or imported files, instead of
creating one archive containing all originals (or one per resulting file). This is a crucial parameter
for the /media/playlist Robot.

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
|
