MicDrop

MicDrop is a configurable desktop soundboard built with Tauri 2.0, React, and TypeScript. Add local audio clips, arrange them in a grid, assign global hotkeys, and play sounds through your default system output or a routed virtual microphone.

Features (v1)

• Modular soundboard grid — configurable columns, pads default to 1x1 and can be resized (up to 4x4) and repositioned in edit mode
• Clip management — import mp3/wav/ogg files, right-click pads to edit/duplicate/delete; editing opens a non-modal, docked properties panel (right rail on desktop, bottom panel on mobile) so the grid stays interactive — you can drag/resize the pad you're editing, or navigate elsewhere, without closing it first
• Playback — HTML5 Audio fallback per clip, per-clip volume, master volume, Stop All
• Call routing (macOS first) — Rust audio engine mixes your microphone with clips and routes the mix to BlackHole 2ch for Discord/Teams/Slack
• Global hotkeys — work even when the app is unfocused (via tauri-plugin-global-shortcut)
• Persistence — board config saved with tauri-plugin-store
• Settings — dark/light theme toggle, audio device selection, virtual cable detection, mic volume/mute, and monitor output controls

Tech stack

• Tauri 2.0 (Rust backend + WebView frontend)
• React 19 + TypeScript
• shadcn/ui + Tailwind CSS v4
• Zustand (state)
• TanStack Router, Form, Hotkeys

Prerequisites

• Node.js 20+
• pnpm
• Rust 1.85+ (for Tauri; run rustup update stable if builds fail on edition2024)
• Platform dependencies for Tauri: see Tauri prerequisites
• BlackHole 2ch for macOS call routing

Setup

pnpm install

Development

Run the app in dev mode (starts Vite + Tauri):

pnpm tauri dev

Build

pnpm tauri build

Production bundles are written to src-tauri/target/release/bundle/.

Rust commands

Command	Description
pick_audio_files	Open native file dialog for mp3/wav/ogg
load_board_config	Load persisted board from store
save_board_config	Save board config to store
sync_hotkeys	Register global shortcuts for clip hotkeys
list_audio_devices	Enumerate input and output devices
detect_virtual_cable	Detect BlackHole/VB-Cable/PipeWire-style virtual outputs
start_audio_engine	Start mic + clip routing to a selected output
stop_audio_engine	Stop native routed audio
play_clip_routed	Queue a clip into the native mixer
stop_all_routed	Stop all routed clip voices

Audio routing notes

MicDrop does not ship a kernel-level virtual audio driver. On macOS, install BlackHole 2ch and select it as MicDrop's virtual output and as your call app's microphone input. Windows and Linux support use the same engine with virtual-cable detection heuristics for VB-Cable and PipeWire-style devices.
