Amplitude Soundboard vs Go Button

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.

Go Button is an iOS app for creating and running sound cue playlists for live performances on iPad, iPhone, and iPod touch. It can play several sounds at once, advance through a cue list with the GO button, or trigger ad-lib effects from Hit buttons. Cues may auto-stop, fade, loop, or duck, with separate volume, pan, speed, and pitch controls. Playback accepts iOS-compatible remotes, Bluetooth keyboards and accessories, MIDI input, OSC commands, and hotkeys. Shows can move through AirDrop or the iOS Files app, arrive from iCloud Drive or Dropbox, and be imported into QLab. Supported audio includes WAV, AIFF, AIFC, M4A, AAC, MP3, MOV, CAF, 3GP, MPEG4 audio, and FLAC; copy-protected files are excluded. It requires iOS 15 or later. The free version costs nothing for one saved playlist; the $99.99, paid once Pro License allows unlimited playlists.
