🎙️ DreamVoice

The ultimate spatial audio, acoustic physics & speech intelligence expansion for Simple Voice Chat on Minecraft (Paper & Fabric)!

Bring real sound physics, soundproof rooms, offline AI speech recognition, keyword spotting, 3D directional speakers, covert spy microphones, walkie-talkie radios, hot-loadable DSP voice filters, real-time acoustic visualizer, and playable audio cassette tapes directly into your Minecraft server.

🌟 What is DreamVoice?

DreamVoice transforms proximity voice chat into a truly immersive, next-generation audio experience. Designed for Roleplay servers, Survival SMPs, Investigation & Mystery games, and Narrative Minigames, it bridges the gap between Minecraft mechanics and real-world audio physics and speech recognition.

With full first-class support for both Paper / Purpur servers (as a plugin) and Fabric servers (as a mod), sound no longer magically passes through thick walls—it bends around open doorways, muffles through solid materials, attenuates inside soundproof rooms, and interacts realistically with the environment.

Players can trigger in-game events by speaking keywords out loud, analyze recorded tapes on lecterns to generate written books, inspect acoustics in real-time with an in-game 3D visualizer, and export audio into MP3/OGG/WAV files. External survival and tech mods can even create craftable speakers, spy bugs, walkie-talkies, and cassette players that interface seamlessly with DreamVoice.

✨ Core Features

🧱 1. Realistic Sound Physics & Soundproof Walls (VoiceWall)

  • Smart Sound Occlusion: Sound realistically stops or muffles behind solid stone, wood, glass, and metal blocks (STRICT_BLOCK or REALISTIC).
  • Acoustic Pathfinding & Diffraction: Sound naturally travels through open doors, windows, and bends around corners.
  • High-Frequency Air Damping: Distant voices naturally lose high frequencies, sounding warmer and muffled through open air over distance.
  • Visual Particle Debugging: Check raycast sound propagation in real-time with visual particles and action bar stats via /voicewall debug [player].

👁️ 2. Real-Time 3D Acoustic Visualizer (/voice visualizer)

  • Live 3D Raycasting: Renders dynamic particle streams in real-time showing line-of-sight sound paths, wall collision impacts, aperture diffraction routes, and speaker audible coverage spheres.
  • Performance-Conscious Hand-Held Mode: To protect client FPS and eliminate visual clutter, particles render only when the inspecting player holds the visualizer tool (Compass) in their main hand.

🏰 3. Acoustic Rooms & Soundproof Zones

  • Soundproof & Reverberant Zones: Define spatial cuboids with custom isolation percentages (isolationPct) and reverb parameters (decay, roomSizeMs, wetGain).
  • Acoustic Presets: Comes with built-in presets (soundproof, studio, cathedral, bunker).
  • Dynamic Filter Stacking: Automatically applies vocal effects (e.g., muffled, echo, cave reverb) upon entering specific rooms and removes them upon exit.

🗣️ 4. Speech Recognition & Real-Time Keyword Spotting (KWS)

  • Real-Time Keyword Spotting: Lightweight background keyword detection powered by offline Vosk models with constrained grammar ([unk], zero hallucinations).
  • Voice-Activated Events: Triggers events for custom roleplay spells, voice-activated doors, passphrases, and minigame mechanics.
  • Smart Audio Gating: RMS noise gate (minEnergyThreshold) and automatic phonetic buffer clearance on pauses (silenceResetMs) to eliminate phantom detections.
  • Interactive Cassette Transcription Stations: Right-click a Lectern or Jukebox with an audio cassette to analyze speech and receive a paginated Written Book with timestamps and speaker names.
  • Hybrid Engine: Works 100% offline inside the JVM (Vosk) or can offload transcription to an external Whisper Sidecar container.

📢 5. 3D Locational Speakers & Physical Broadcasts

  • Place directional 3D speakers anywhere in your world at static coordinates.
  • Attach to Entities: Mount speakers to moving vehicles, drones, ArmorStands, or NPCs!
  • Dual Channels: Speak through a microphone while playing background music/sound effects simultaneously with zero collision.
  • Podium & Intercom Broadcasts: Broadcast points route voices within a capture radius to target speakers or across the whole server.

👻 6. Voice Projections & Security Cameras

  • Project your voice remotely to any target block or moving entity.
  • Hear what the camera or remote point hears—ideal for CCTV security cameras, intercoms, surveillance drones, or magical projections.

🕵️ 7. Covert Wiretaps & Spy Bugs

  • Plant hidden microphones at secret coordinates or mount a bug directly on an NPC or player.
  • Listen in real-time to secret conversations or record them directly to an in-game cassette tape!
  • Cross-Module Propagation: Wiretaps realistically intercept voices emitted from voice projections.

📼 8. Audio Cassettes & Multi-Format Audio Export

  • Record live voice conversations with zero-CPU direct Opus streaming (OpusAudioPlayer).
  • Generates a physical Cassette item that players can hold and play with a right-click or load into 3D speakers.
  • Async Audio Export: Export any session recording directly into MP3, OGG, or WAV files via /record export.
  • Timeline Slicing: Extract specific segments or the final N seconds from any recording (/record slice).

📻 9. Walkie-Talkies & Radio Channels

  • Connect players to specific radio frequency channels for team tactical comms, police dispatch, or survival walkie-talkies.
  • Authentic analog band-pass filter (300 Hz - 3400 Hz) with push-to-talk mic clicks.
  • Directional Transmitters: Point-to-point voice transmission with customizable ranges.

🎛️ 10. Dynamic DSP Voice Filters & File-First Pipeline

  • Transform player voices on the fly with 13 built-in filters (alien, cave, deep, disguise, gasmask, ghost, helium, megaphone, muffled, radio, robot, telephone, underwater).
  • Hot-Reloadable Files (.yml, .json, .java):
    • Declarative DSP pipelines (lowpass, highpass, gain, overdrive, ring_modulator, delay/echo).
    • On-the-fly JDK compilation for custom .java filter source files.
  • Filter Exporter: Export active filters into pipeline YAML/JSON or Java source files (/voice filter export).
  • Built-in Soft-Knee Dynamic Limiter prevents microphone clipping and distortion.

🛠️ 11. Interactive Configuration GUI (/voice config)

  • Open a full visual GUI dashboard to configure and monitor all modules without touching config files.
  • Interactive tool (Echo Shard) to target entities, blocks, or positions in real-time.

📡 12. Fabric Network Packets & Inter-Mod Ecosystem

  • 40+ custom packets (@DreamPacket) allowing third-party survival, tech, and companion mods to create and control speakers, wiretaps, radios, cassettes, and filters without hard compile dependencies.
