Audio Encoding. Built for Developers.
Encode, merge, loop, extract artwork, and generate waveforms — all automated in a Simple API.
Compress audio up to 90% while preserving quality with modern codecs.
Convert, merge, and enhance audio files with powerful Robot chains.
Transcribe speech, generate audio, and extract metadata automatically.
Transform Your Audio
At Transloadit, a Robot is an automated worker that performs a single task in your audio workflow — like extracting cover artwork, encoding audio, or concatenating audio files.

Encode Audio Files
Convert audio files into all kinds of formats. Like MP3, AAC, and more.
/audio/encode - cover.jpgrock-angel.mp3320 kbps
Extract Cover Artwork
Extract embedded cover artwork from audio files.
/audio/artwork - 3 takes · one file
Concatenate Audio Files
Concatenate several audio files together into a single audio file.
/audio/concat - 0:45Target 3:00
Loop Audio Files
Loop one audio file as often as is required to match a given duration.
/audio/loop - 2 tracks · one mixvoice.wavmusic.mp3
Merge Audio Files
Overlay several audio files on top of each other.

Build Audio Pipelines by Chaining Robots
Chain Robots together to create end-to-end automated pipelines for audio processing.

Audio workflows without the pain
Start with MP3, AAC, Opus, FLAC, or WAV presets, then override supported FFmpeg parameters for codecs, bitrates, channels, filters, and containers.
Parallel ingest and edge delivery cut startup time across regions.
Signed uploads, scoped credentials, and compliance-aware storage options keep your audio pipelines safe.
No servers to provision or maintain. Our cloud workers auto-scale with your traffic. Just API calls — we handle the rest.
Export encoded audio to Amazon S3, Azure Blob Storage, Backblaze B2, Box, Cloudflare R2, DigitalOcean Spaces, Dropbox, Google Cloud Storage, MEGA S4 Object Storage, MinIO, OpenStack Swift, Rackspace Cloud Files, Supabase, Tigris, and Wasabi.
Typed SDKs, deterministic Assemblies, and flexible Robots. CI-safe audio pipelines you can version-control.
Take Audio Encoding into production
The guides, Robot reference, and working demos teams reach for when Audio Encoding has to run reliably at scale.
“It was quick and straightforward to setup our Templates and within a couple of hours, we had swapped out our code and were uploading and encoding audio.”
James Lovatt, Co-founder and CTO at Promo Push
Guides
- Control video and audio codecs with TransloaditChoose video and audio presets, override supported FFmpeg options, select an FFmpeg stack, and test codec outputs without operating an encoding fleet.
- A beginner’s guide to FFmpeg with PythonA safe introduction to running FFmpeg from Python and deciding when to move the workload to a managed media pipeline.
- Media automation: from upload to reliable outputAutomate repeatable media intake, transformation, validation, and export while preserving observability and control.
- A complete guide to digital-asset workflowsDesign a digital-asset workflow from intake and processing through review, publication, retention, and deletion.
What Audio Encoding costs to run
Every plan runs every Robot, so nothing about this service is held back for a bigger one. You are paying for the volume you put through it.
