Amplitude Soundboard vs EXP Soundboard

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.

EXP Soundboard is a free, open-source soundboard for playing custom clips through speakers or virtual audio devices. Users can load MP3 and WAV files, assign hotkeys for playback, adjust each sound’s volume, and configure the output. It also includes text to speech for playing custom messages. Gamers, streamers, and content creators are among its intended users. Audio can optionally be routed to Discord or OBS through Virtual Audio Cable or similar tools. The software is designed for Windows, with Windows 7, 8, 10, and 11 listed as compatible. It is also listed for Linux, macOS, and web: Mac and Linux use is through a virtual machine or Wine, while browser use runs through OnWorks in a virtual Windows environment. After installation, it works offline, except when used through OnWorks. Minimum requirements include Windows 7, a 1 GHz Intel or AMD CPU, 1 GB RAM, 50 MB free disk space, and Java Runtime Environment 8 or later. The site says the installer may be flagged by antivirus software and advises downloading from trusted sources.
