What is Amplitude Soundboard?

Updated

Amplitude Soundboard is a free, open-source soundboard application for Windows, Linux, and macOS, built with .Net 6 and Avalonia. It's for anyone who wants to trigger audio clips on demand — through hotkeys or by clicking tiles — and route that audio to either output devices (like speakers) or input devices (so other apps treat the soundboard as a microphone). It's a good fit if you want a cross-platform tool with per-clip control and a customizable grid; it's less suited if you need a hosted or browser-based solution, since this is a desktop app you download and run.

What it does

The core workflow is simple: load audio files, arrange them as tiles in a grid, and play them when you need them.

  • Play audio clips through output or input devices. Routing to an input device lets other software (voice chat, streaming tools, recording apps) pick up the soundboard audio as if it were a microphone. On Windows this relies on Virtual Audio Cable, on macOS on BlackHole, and on Linux on Pulse Audio commands.
  • Global and per-clip volume. You can set an overall level and then adjust individual clips independently, so a loud clip doesn't have to match a quiet one.
  • Hotkeys. Any sound clip can be bound to a hotkey and triggered at any time, which is the main reason to use a soundboard over just playing files manually.
  • Customizable tile grid. Light and dark themes, a custom background image per clip, adjustable tile size, and configurable row and column counts.

Supported audio formats

AAC, AIFF, ALAC, FLAC, M4A, MP3, MP4, OGG, OPUS, and WAV. That covers the common lossy and lossless formats plus a few container types, so you generally won't need to convert existing files.

Languages

The interface is available in a growing set of languages, currently including English, Spanish, Italian, Hungarian, Dutch, Polish, Russian, and Simplified Chinese. The project invites contributions to expand the list.

Platform and licensing notes

  • Platforms: Windows, Linux, macOS — the same application across all three, which is the main practical difference from soundboards tied to a single OS.
  • Cost: The project describes itself as free and open-source, and links to its source code for download. No pricing tiers or paid features are mentioned on the page.
  • Development status: It's described as feature-rich and in active development, so expect the feature set to change over time.

When to choose it

Pick Amplitude Soundboard if you want a desktop soundboard that works across Windows, Linux, and macOS, supports hotkey triggering, and lets you send audio into other applications via a virtual audio device. If your main need is a web-based soundboard or one that runs without installing a virtual audio cable for input routing, this isn't that — the input-device feature depends on those external tools on each platform.
