Even with a HiFi ARL, some third-party tools struggle to distinguish between "HiFi" and "Premium" tiers. You may need to force FLAC selection manually.
Treat your ARL like a password. If someone gets it, they can stream on your account, change your settings, and potentially lock you out. Do not paste it into random Discord bots. Part 3: The HiFi Experience via ARL (Unofficial vs. Official) I decided to run a test. I have a standard Deezer HiFi subscription. I listened to Steely Dan’s Aja (the gold standard for lossless testing) in three scenarios. Scenario A: The Official App Sound: Crisp, detailed. The low end on "Black Cow" was tight. Feeling: Frustrated. The app lagged when scrolling through my 4,000+ liked songs. Memory usage: 400MB+. Scenario B: The Web Player (Chrome) Sound: Noticeably worse. Deezer limits web playback to 320kbps MP3/AAC. The cymbals sounded like static. Unacceptable for HiFi. Scenario C: A Third-party CLI tool using my ARL Sound: Pure FLAC direct to my DAC. Bit-perfect. Feeling: Liberated. I was listening inside mpv with custom SoX resampling. Memory usage: 45MB. deezer hifi arl
Streaming via a CLI tool? Fine. Using your ARL to download 10,000 FLACs to seed on a torrent site? That hurts the artists and will get your account banned instantly. Part 7: Should You Bother? If you are a casual listener who uses AirPlay or Bluetooth earbuds—stick to the official Deezer app. It’s fine. Even with a HiFi ARL, some third-party tools
