Audyn

Audyn is a fake Newznab indexer and download client that integrates Deezer into the *arr stack. It speaks Newznab to Prowlarr and SABnzbd to Lidarr, while actually searching and downloading from Deezer.

How it works

• Indexer: Audyn pretends to be a Newznab usenet indexer, forwarding search queries to the Deezer API
• Downloader: Audyn pretends to be a SABnzbd download client, downloading tracks directly from Deezer

Stack

• Prowlarr → Audyn (Newznab)
• Lidarr → Audyn (SABnzbd)
• Audyn → Deezer API

Setup

1. Get your Deezer ARL token

Log in to deezer.com, open DevTools → Application → Cookies and copy the value of the arl cookie.

2. Configure docker-compose.yml

Clone the repo and edit compose.yml:

services:
  audyn:
    build: .
    container_name: audyn
    restart: unless-stopped
    ports:
      - "5000:5000"
    environment:
      # Deezer ARL cookie
      DEEZER_ARL: "your-arl-here"
      # Quality: 0=MP3_128  1=MP3_320  2=FLAC (requires Deezer HiFi)
      # DEEZER_QUALITY: "1"
      AUDYN_PORT: "5000"
      AUDYN_INCOMPLETE_PATH: /downloads/incomplete
      AUDYN_COMPLETE_PATH: /downloads/complete
      # The path Lidarr sees (if Audyn and Lidarr mount the same volume under different paths)
      AUDYN_COMPLETE_PATH_MAPPING: /downloads/complete
    volumes:
      - /your/downloads/path:/downloads

Make sure the download path matches what Lidarr has mounted as its download folder.

3. Start Audyn

docker compose up -d

4. Add Audyn to Lidarr

As an indexer (Settings → Indexers → Add → Generic Newznab):

• URL: http://audyn-host:5000
• API Path: /api
• API Key: anything, e.g. audyn

As a download client (Settings → Download Clients → Add → SABnzbd):

• Host: audyn-host
• Port: 5000
• URL Base: download
• API Key: anything, e.g. audyn

5. Lidarr settings

Settings → Media Management:

• Delete empty folders: true
• Allow Fingerprinting: Always

Settings → Quality:

• Increase the maximum file size for FLAC - downloads get large quickly and Lidarr will reject them otherwise.

Permissions:

• Audyn creates folders with 0o755
• Set chmod Folder to 755 in Lidarr under Settings → Media Management

Troubleshooting

"One or more tracks expected in this release were not imported or missing from the release"

This usually means Lidarr couldn't match the Deezer release to a MusicBrainz entry closely enough which is common with less known artists.
Go to Wanted → Manual Import, navigate to the download folder and manually assign the correct album.
