Echo Vision

You are blind. The world is pitch black. Every sound you hear — your own footsteps, a jump, a door, a zombie's groan, a friend talking in voice chat — sends out a wave that rolls through the air, around corners and down tunnels, and for a few seconds reveals the world in black and white.

Listen. Move carefully. Make noise to see — and remember that everything else can hear you too.

✨ Features

• Real blindness. No sky, no light, no outlines. Without sound you see nothing.

• Every sound is an echo. Steps, jumps and landings, mining, combat, mobs, doors, note blocks — the louder the sound, the farther its wave reaches.

• Sound travels like sound. Waves go through the air only: down corridors, through doorways and around corners, getting weaker at every turn. Walls block them — no X-ray.

• Round, smooth wavefront. A thin bright ring races across floors and walls at the speed of sound (configurable), then the revealed surfaces slowly fade.

• Echo Vision look. Revealed blocks keep their real models and textures, rendered in grayscale with fine lines along texture details — inspired by sonar and the Deep Dark.

• Mobs in the same style. Creatures are revealed the moment the wave reaches them — and fade back into the dark.

• Active echolocation. Press V to click your tongue and send a pulse.

• Voice chat support. With Plasmo Voice or Simple Voice Chat, your voice and other players' voices create waves. Louder speech reaches farther; whispers barely do.

• Fully configurable. Almost 40 options in-game: speed of sound, range, wave ring, glow time, brightness, color (white by default, any hue, by sound type or by distance), which sounds count, and more.

  

🎮 Controls

All keys can be changed in Options → Controls.

🔊 How sound spreads

Each sound is traced through the block grid from its source. The wave follows open air — tunnels, doorways, staircases — and loses strength with distance and with every corner it has to bend around. In the open it forms a perfect sphere; around a corner it smoothly wraps the corner and continues down the corridor. Surfaces light up exactly when the wavefront touches them.

🧩 Compatibility

• Sodium — supported (tested with Sodium 0.8.12).
• Iris — works, but shader packs are not supported: with a shader pack enabled the darkness and echoes won't look right.
• Plasmo Voice / Simple Voice Chat — optional; voices create echoes. Voice must also be installed on the server for multiplayer.
• Mod Menu — optional, adds a settings button.
• Client-side only. Works in singleplayer and on any server.

❓ FAQ

Is this a cheat on servers?
No — it only removes information. You see only what sound reveals, and walls block it.

Can I make it less dark?
Yes: Settings → Vision without echo lets you see a few blocks around you even in silence.

Jumping in place doesn't make vanilla sounds — will it still echo?
Yes. Echo Vision adds its own quiet sounds for jumps and landings (sneaking makes them quieter).

The old contour / grid look?
Still there: Settings → Style has Object contours, Block grid and Filled faces.

🇷🇺 На русском

Ты слеп. Мир чёрный. Каждый звук — твои шаги, прыжок, дверь, рычание зомби, голос друга в голосовом чате — пускает волну, которая идёт по воздуху, огибает углы, заходит в туннели и на несколько секунд показывает мир в чёрно-белом.

• Настоящая слепота: без звука не видно ничего.
• Каждый звук — эхо: шаги, прыжки и приземления, копание, удары, мобы, двери. Чем громче звук, тем дальше волна.
• Звук ведёт себя как звук: идёт только по воздуху — по коридорам, через проёмы, за углы, слабея на каждом повороте. Сквозь стены не проходит.
• Круглая плавная волна: тонкое яркое кольцо бежит по полу и стенам со скоростью звука (настраивается).
• Эхо-зрение: блоки с настоящими текстурами в оттенках серого с линиями деталей. Мобы — в том же стиле.
• Щелчок (V) — активная эхолокация.
• Голосовой чат: с Plasmo Voice или Simple Voice Chat голос даёт волну.
• Почти 40 настроек (K или Mod Menu).

Клавиши: V — щелчок, B — эхо вкл/выкл, N — слепота вкл/выкл, K — настройки.
Совместимость: Sodium — да, Iris — да, но без шейдерпаков. Только клиент.
