Audio Encoding
The quality of an audio track — its ability to get the crispest details across — is determined in large part by the way it is encoded. Different formats also come in different sizes, which makes file encoding an important tool to keep file sizes and data usage down. Transloadit offers a wide variety of audio encoding features to maximize file compatibility across platforms, as well as enrich audio with effects, loops, overlays, and more, to get the most out of your (user generated) audio content.
Robots
At Transloadit, we call our features Robots because you can make them work together to create encoding pipelines unique to your use case.
-
/audio/artwork
extracts the embedded cover artwork from audio files and allows you to pipe it into other Steps, for example into /image/resize Steps. It can also insert images into audio files as cover artwork -
/audio/concat
concatenates several audio files together -
/audio/encode
converts audio files into all kinds of formats for you. We provide encoding presets for the most common formats -
/audio/loop
loops one audio file as often as is required to match a given duration -
/audio/merge
overlays several audio files on top of each other -
/audio/waveform
generates waveform images for your audio files and allows you to change their colors and dimensions
