Our AI-powered Robots
Build Audio Pipelines by Chaining Robots
Chain Robots together to create end-to-end automated pipelines for audio processing.
{"steps": {":original": { "robot": "/upload/handle" },"encode_mp3": {"use": ":original","robot": "/audio/encode","preset": "mp3","ffmpeg": { "ab": "320k", "ar": "44100" }},"artwork": {"use": "encode_mp3","robot": "/audio/artwork","format": "jpg","width": "280""height": "280"},"waveform": {"use": "artwork","robot": "/audio/waveform","width": "280","height": "80"}// ... use an export robot to save to S3, FTP, etc.}}
Audio workflows without the pain
MP3, AAC, WAV, and more with tuned presets, two-pass, and per-title encoding. Get crisp audio at the smallest size.
Parallel ingest, turbo transcodes, and instant 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.
First-class S3, GCS, and Azure support. Originals stay put, results export straight to your buckets.
Typed SDKs, deterministic Assemblies, and flexible Robots. CI-safe audio pipelines you can version-control.
Developers that use Transloadit
I'm not usually one for fanboy-ism but Transloadit is one service I would recommend without hesitation. Their product and customer support is outstanding.
Having a solution for both uploading and transcoding has been a godsend for the current scale that we are at five years after first choosing Transloadit.
Using Transloadit saves development and maintenance. Being able to focus on our product instead of reinventing the wheel cannot be understated.
