Control your HEOS speakers and Denon/Marantz receivers from your desktop. Browse, play, and manage multi-room audio. Take command of your whole-home audio system: Audio Hero is a sleek, purpose-built desktop controller for HEOS-compatible speakers and Denon/Marantz AV receivers. Discover devices on your network automatically, browse your music services, control playback, and manage multi-room audio — all from one elegant dark-themed interface. This is not an official 'HEOS by Denon' application and is not affiliated with the Denon, Marantz, or HEOS brands in any way. It cannot be used to setup your HEOS devices. 🔊 Instant Device Discovery Plug in and go. Audio Hero automatically finds every HEOS speaker and Denon/Marantz receiver on your home network using SSDP discovery. Connect with one click, or enter an IP manually if you prefer. The app remembers your devices and can auto-connect to your last-used speaker on startup — zero configuration needed. 🎵 Browse All Your Music Sources Navigate your entire music library with an intuitive Finder-style column browser. Sign into your HEOS account to access streaming services like TuneIn, Spotify, Amazon Music, Deezer, SoundCloud, and more. Browse through genres, artists, albums, and playlists with smooth drill-down navigation. Reorder your music sources with drag-and-drop to put your favorites first. 🎶 Play Local Audio Files Turn your PC into a music server. Select files or entire folders of music and stream them directly to any HEOS speaker on your network. Audio Hero spins up a lightweight local server behind the scenes — no setup required. Supports MP3, FLAC, WAV, AAC, M4A, WMA, OGG, and ALAC formats. Full queue management with shuffle, repeat (all/one), and track-by-track navigation. 🎚️ Precision Playback Controls Full transport controls: play, pause, stop, skip forward, skip back — plus 15-second skip buttons for quick navigation. Seekable timeline with click-to-seek. Volume slider from 0–100 with numeric precision input. Set a maximum volume limit to protect your ears (or your neighbors). Save up to three volume presets for instant recall — perfect for switching between background music and party mode. 👍 Track Voting Rate tracks with thumbs up and thumbs down. Votes are saved locally and persist across sessions. Enable auto-skip on thumbs down to automatically skip past songs you don't like. 🔁 Repeat & Shuffle Cycle through repeat modes (Off → All → One) and toggle shuffle — works with both streaming services and local file playback. Visual indicators show the current mode at a glance. 🏠 Multi-Room Speaker Groups (Pro) Create and manage speaker groups to play synchronized audio across multiple rooms. Select a leader speaker, pick which other speakers join the group, and enjoy whole-home audio with a few clicks. Dissolve groups just as easily when you want independent control. 📡 Full Denon/Marantz Receiver Control (Pro) Go beyond basic playback. Audio Hero connects directly to your Denon or Marantz AV receiver over its network control protocol and gives you access to 55+ controls including: **Power & Input Selection** — Switch between HDMI, optical, Bluetooth, USB, and 25+ input sources **Surround Sound Modes** — Dolby Digital, DTS, Auro-3D, Stereo, Pure Direct, and 20+ modes **Audyssey Calibration** — MultEQ, Dynamic EQ, Dynamic Volume, Reference Level Offset **Tone Controls** — Bass, treble, individual channel trim (Front L/R, Center, Subwoofer, Surround L/R) **Zone 2 Control** — Independent power, input, volume, and mute for a second room **System Settings** — Sleep timer, eco mode, display dimmer, auto standby, Bluetooth TX **Tuner** — Frequency and preset control for built-in radio 🎨 Rich Track Metadata *(Pro)* See more than just a song title. Audio Hero queries four music databases in parallel — TheAudioDB, Deezer, MusicBrainz, and Wikipedia — and merges the results intelligently. Get artist biographies, genre, mood, release year, country of origin, formation year, audience stats, and high-quality cover art. Works with both streaming services and local files. 🖥️ Compact Modes Switch to a streamlined compact view when you want Audio Hero to stay out of the way. Full-size mode gives you the complete browsing and control experience at 1130×750. Compact mode shrinks to a tidy 600×420 with just the essentials. 📌 System Tray Integration *(Pro)* Minimize Audio Hero to your system tray and keep controlling your music from a sleek popup. The tray mini-player shows album art, track info, and gives you play/pause, skip, mute, and volume controls — all without restoring the main window. ⌨️ Keyboard Shortcuts Control playback without touching your mouse: - **↑ / ↓** — Volume up / down - **← / →** — Previous / next track - **Space** — Play / pause 🌙 Beautiful Dark Theme Audio Hero features a refined dark interface built on the Cappuccino Mocha color palette — easy on the eyes during late-night listening sessions, with blue accents that look great on any display. 🔄 Automatic Updates Audio Hero checks for new versions and notifies you with a subtle banner.
