audy
REST + webhooks + MCP

Programmable audio cleanup, with receipts.

Audy is a developer API for improving audio — denoise, de-hum, de-ess, loudness-normalize, transcribe — composed into named, versioned workflows that sound identical on every file. Every result carries its full processing chain. Async, quality-preserving, agent-native.

Not another one-off magic button

Enhancement tools give you a black box and a different result every time. Audy gives you a pipeline you can name, version, audit, and ship.

🔁

Repeatable by construction

Save a chain once; run it identically forever. Workflow versions are immutable — episode 40 sounds like episode 12, provably.

🧾

Receipts on every job

Provenance records the exact processing chain, input/output formats, lossy-source detection, and measured loudness. Auditable pipelines, not vibes.

🔌

Bring your own plugins

Audy hosts the AudioUnits/VSTs you already own — factory presets included — exposed with full parameter schemas. Your studio's sound, as an API.

🤖

Agent-native

A first-class MCP server with 20 tools means Claude, Cursor, or your own agent can operate the whole toolkit. Give your agent an audio engineer.

🎚️

Quality-preserving by design

Decode once to float, no intermediate lossy stages, video tracks stream-copied — never re-encoded. Loudness to broadcast and platform specs (EBU R128).

🪣

Your buckets, not ours

Audy reads from and writes to your S3-compatible storage and keeps nothing by default. Ephemeral scratch space expires on a clock.

Async by design: POST, then get a webhook

No long-lived connections to babysit. Create a job, go do something else, and Audy calls you back with the result and its receipt.

1

Point at your audio

An S3 reference to your bucket, or a short-lived direct upload for files you have in hand.

2

POST /v1/jobs → 202

Pick a preset, a saved workflow, or a plugin chain. Tune denoise strength, target LUFS, and more per job.

3

Webhook or poll

Result lands in your bucket; the job record carries the full provenance chain and measured loudness.

Reuse it: workflows are versioned

# save the house sound once…
POST /v1/workflows
{ "name": "podcast-house-sound",
  "nodes": [ {"kind": "preset", "preset": "cleanup-v1"},
             {"kind": "op", "op": "loudnorm", "target_lufs": -16} ] }

# …then every episode is one line, forever
POST /v1/jobs
{ "source": {…}, "workflow": "podcast-house-sound@1" }

Transcripts & captions, word-level

# transcription with word timestamps,
# SRT/VTT captions, chapters, show notes
POST /v1/jobs
{ "source": {…}, "preset": "transcribe-v1" }

# loudness compliance, measured & reported
POST /v1/jobs
{ "source": {…}, "preset": "cleanup-v1",
  "target_lufs": -23 }   # EBU R128 broadcast

Give your agent an audio engineer

The MCP server is a thin proxy over the same REST API — no contract drift. Twenty tools, from one-shot helpers to full workflow composition, ready for Claude, Cursor, or your own agent loop.

  }
}

“Clean up this interview, normalize it for Spotify, give me chapters and show notes” — that's one prompt, not an afternoon. Your agent picks the tools; every result still carries its receipt.

Built for people who ship audio features

Developers embedding audio

UGC platforms, course tools, meeting products, voice apps — clean user audio without building a DSP team.

Podcast tools & networks

A consistent, provable house sound across every show and episode — and receipts when someone asks why it sounds different.

AI & agent builders

Audio processing your agent can drive end-to-end over MCP, with structured results it can reason about.

Teams replacing an aging audio API

Portable by design: Docker for dev, Terraform for AWS, and your own buckets for storage. No lock-in on the media path.

What Audy is not (yet)

  • Not a consumer editor. Audy is an API-first backend — there's no GUI timeline, and that's on purpose.
  • Not a “magic AI voice” model. The bet is composability, BYO plugins, and receipts — not best-in-class neural enhancement. If you need a one-button miracle, other tools do that; they just can't prove what they did.
  • Not storage. Audy reads and writes your buckets and keeps nothing by default.

Metered like the infrastructure it is — no seats, no tiers to outgrow. Usage is measured per processed audio-minute and every charge reconciles against the same usage events you can query.
