Audio infrastructure for apps and platforms

Add reliable audio handling to any product.

Accept audio uploads, turn inconsistent source files into clean and predictable outputs, and deliver the right version securely to every listener. AudioDN gives your product a production-ready audio pipeline without requiring your team to build and operate one.

Use the complete upload-to-playback workflow—or only the processing, storage, delivery, API, or interface components you need.

Processed, secured, and ready to play

Music by Nyktrn

Your product should not have to care what audio file it receives.

Users upload different formats, bitrates, codecs, channel layouts, metadata, and quality levels. Building around every possible input creates fragile playback, inconsistent downloads, and a growing collection of processing jobs and storage rules.

AudioDN turns those inputs into a predictable set of files and data that the rest of your product can rely on.

Accept unpredictable uploads

Let users, customers, creators, agents, or internal teams upload common audio formats directly. AudioDN inspects each file and starts your configured processing workflow automatically.

Create consistent outputs

Standardize formats, codecs, bitrates, quality levels, stereo or mono output, previews, waveform data, and downloadable versions. Optionally strip embedded metadata when creating new variants.

Deliver the right audio

Serve public, private, paid, preview, streaming, or downloadable audio through scoped access, signed URLs, and global edge delivery.

How it works

Upload once. Create every version you need.

1

Ingest

Your application, website, users, or internal team uploads an audio file through the API, dashboard, or uploader component.

  • Direct-to-storage uploads
  • Signed upload sessions
  • User-facing or server-side workflows
  • No need to proxy large audio files through your application server
2

Process

AudioDN runs the processing configuration associated with the collection or workflow.

  • Playback-ready transcodes
  • High- and low-quality variants
  • Short preview clips
  • Download formats
  • Waveforms and audio analysis
  • Metadata extraction or stripping
  • Original-file retention when configured
3

Deliver

The resulting audio is made available to your product through the API, secure delivery URLs, or AudioDN components.

  • Public or protected playback
  • Scoped sessions and signed URLs
  • Global edge delivery
  • Webhook-based lifecycle updates
  • Custom interfaces or drop-in components
Variant types Upload sessions Signed delivery Track-processing webhooks

Built for products that work with sound.

AudioDN is not limited to music streaming. It provides the underlying audio workflow for any product that needs reliable uploads, consistent files, controlled access, or playback.

User-generated audio

Accept voice notes, recordings, submissions, lessons, performances, interviews, or other user-uploaded sound without requiring every user to provide the same file format.

SaaS and marketplaces

Give multiple customers or creators their own collections, upload workflows, playback access, and processing configurations.

Audio and music commerce

Generate short previews while keeping full-quality streaming or downloadable files behind your own entitlement and purchase checks.

Podcasts and media

Create standardized playback files, lower-bandwidth versions, waveform data, and downloadable formats from one source upload.

Voice and communications

Handle voicemail, answering-service recordings, call recordings, support messages, dispatch audio, and other speech-oriented workflows.

Custom applications

Use AudioDN as a headless processing and delivery backend while maintaining a completely custom application and user experience.

Use the whole pipeline—or just the part you need.

AudioDN is designed as a set of connected services rather than an all-or-nothing player product. Start with one part of the workflow and adopt more as your product grows.

Audio processing

Turn inconsistent source files into a reliable set of formats, quality levels, clips, downloads, waveform data, and other configured outputs.

Explore variant types

Secure audio delivery

Control how long audio can be accessed, which tracks or collections a credential can reach, and whether a listener can stream or download a file.

Learn about signed delivery

Upload infrastructure

Let browsers, mobile applications, customers, or internal systems upload directly through scoped sessions without routing large files through your backend.

View upload options

Playback and interfaces

Use the AudioDN player, uploader, and waveform components, or retrieve the same resources through the API and build a completely custom interface.

View components

Product and commerce workflows

Create preview variants, downloadable editions, protected full-length files, or multiple delivery qualities from the same upload.

The interface is optional. The infrastructure is not.

The player at the top of this page is one way to use AudioDN. Use it as-is, customize it through supported options, or build your own experience using the same processed files and delivery APIs. Cover artwork, playback, waveform behavior, and collections or track lists are all driven by the variants AudioDN generates from a single upload.

Technical proof

Straightforward enough to test today.

Create an upload session, upload the source file, and make the processed track available to your application. Use the REST API from any backend, or let AudioDN components handle the browser-side workflow. 

# 1. Create an upload session (server-side, with your API key)
curl -X POST "https://api.audiodelivery.net/v1/upload_session" \
  -H "Authorization: Bearer $ADN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "collection_id": "COLLECTION_ID" }'

# Response includes upload_session_id.

# 2. Create a track in the session to get a per-track upload URL
#    (one request per file; the session ID authorizes it)
curl -X POST "https://api.audiodelivery.net/v1/upload/$UPLOAD_SESSION_ID/track" \
  -H "Content-Type: application/json" \
  -d '{ "file_name": "track.wav" }'

# Response includes track_id and track_upload.upload_url.

# 3. Upload the file directly to the signed URL
curl -X PUT "$TRACK_UPLOAD_URL" --data-binary @track.wav

# 4. Wait until the track is ready (poll, or use a webhook)
curl "https://api.audiodelivery.net/v1/track/$TRACK_ID" \
  -H "Authorization: Bearer $ADN_API_KEY"
# -> track.track_status_id becomes "ready" when processing finishes

# 5. Mint a play session for a listener
curl -X POST "https://api.audiodelivery.net/v1/play_session/track" \
  -H "Authorization: Bearer $ADN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "track_id": "TRACK_ID", "variants": ["hq", "lq"], "expires_in": 3600 }'
# -> first_track.variants[].url are signed, time-gated playback URLs
API reference OpenAPI specification Integration guides

Control access without building a media-security layer.

Use scoped client-side credentials, server-created play sessions, or server-signed delivery URLs based on how much control your application requires.

Scoped player and uploader credentials

Short-lived play sessions

Time-limited signed URLs

Track- or collection-level access

Configurable download variants

Server-side credentials that stay off the client

Encryption in transit and at rest

Optional referrer, origin, or IP policies on supported plans
