Make audio useful everywhere

Build the workflow listeners never have to think about

A format change is often only the beginning. Normalize playback, create searchable transcripts, generate visual assets, and deliver every result to the systems your product already uses.

  • Consistent playback

    Normalize incoming audio into formats and settings your product can rely on.

  • Searchable speech

    Turn speech into text that can power search, captions, summaries, and analysis.

  • More than one output

    Create waveforms, previews, and alternate outputs alongside the primary track.

  • Flexible ingestion

    Process uploaded audio or import it directly from storage and remote sources.

  • Connected workflows

    Send completed files to your storage and notify your application with webhooks.

  • Parallel processing

    Run independent Steps in parallel instead of waiting for a long serial pipeline.

Frequently asked questions

How does the Audio transcription tool work?

Upload a supported audio file, run the tool, and download the transcript. The page sends your upload through Uppy into a real Transloadit Assembly, so the result demonstrates the same processing platform available through the API.

What is the maximum file size?

Files can be up to 25 MB on this public utility. Production workflows can accept larger files, process batches, import directly from cloud storage, and create several outputs in parallel.

Are uploaded files stored permanently?

The public tool processes files temporarily. Do not upload sensitive material. A production workspace gives you control over authentication, storage destinations, and retention.

Can I automate audio transcription with an API?

Yes. The same processing capability is available through reusable Transloadit Templates. Trigger it from Uppy, a backend SDK, an API request, or a Smart CDN URL, then send results to storage and services you control.

What other file tools are available?

Browse the audio tools category for related utilities. Each page runs a real upload and produces a downloadable result.

Process uploads, batches, and cloud files with one workflow

Move this same capability into your product: process customer uploads and cloud files, then route the results to storage, webhooks, and delivery.
