Amplitude Soundboard vs Soundboard Studio

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 Studio is an iOS cartwall app for playing audio such as pads, music beds, voiceovers, sound effects and soundbites. It is presented for podcasts, shows and gigs, as well as studio, broadcast and theatre use. Any number of tracks can play at once, with a separate volume control for each. Tracks can be trimmed using a waveform, looped, faded in or out, or set to stop other tracks when played. Automations can play, stop or change the volume of other tracks when a track starts, stops or reaches its end. Audio can be bulk imported from Dropbox, Google Drive, iCloud Drive and other sources. The free version allows up to 24 tracks across four boards, but does not include background playback when the app is closed or track automations. Pro adds unlimited tracks and boards, background playback and automations. The weekly option is $6.99 a week and the yearly option is $59.99 a year; both begin with a 7-day free trial. A lifetime Pro purchase is $159.99 USD. The app is described as universal for iPad, iPhone and iPod touch. Its privacy policy says audio files and track settings are stored locally, and that personal information and analytics data are not collected.
