Amplitude Soundboard vs Soundboard Online

Amplitude Soundboard is a desktop app for playing audio clips to express yourself and entertain friends. It runs on Windows, macOS, and Linux, with downloads listed for Windows x64, macOS on Apple Silicon and Intel, and Linux x64. Supported formats include AAC, AIFF, ALAC, FLAC, M4A, MP3, MP4, OGG, OPUS, and WAV. Clips can play through multiple output or input devices, with volume controls for the full app and individual clips. Users can assign hotkeys to sounds. The interface offers light or dark themes, custom tile backgrounds, and controls for tile size and grid dimensions. Listed languages include English, Spanish, Italian, Hungarian, Dutch, Polish, Russian, and Simplified Chinese. The app is free at free, and its repository is identified as GPL-3.0 licensed. The project page describes update notices at startup and automatic updating on Windows. Routing sound to an input such as a microphone requires additional audio-routing software. Linux hotkeys work under X11, not Wayland; macOS hotkeys require accessibility permission and an app restart, and a security warning may need to be bypassed because the app is not signed with an Apple Developer ID.

Soundboard Online is a free browser soundboard for playing uploaded clips together in real time. You can create private rooms, share links and let connected members hear the same sounds simultaneously. Persistent WebSocket connections broadcast play events to everyone in a room. The service accepts MP3, WAV and OGG files up to 50 MB per clip. A visual waveform editor trims clips, and keyboard hotkeys trigger them. You can paste a YouTube link to stream background music for room members. The product is aimed at Discord servers, Twitch and YouTube streamers, D&D sessions and remote teams. Its HTTP API connects with Twitch bots, Stream Deck, Cloudflare Workers, Discord or Slack bots, Home Assistant and scripts. API keys are shown once, stored hashed and limited to playing sounds in their originating room. Soundboard Online runs in a browser with no desktop app. The Free Forever plan costs nothing, has no subscription or credit card, and places no cap on rooms, clips or sessions. Users must be at least 13.
