Go Button vs Stadium Sound

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.

Stadium Sound is a soundboard for stadium and arena PA operators managing walk-on music and sound effects. Tracks can be grouped into named banks and queued across banks in an ordered playlist. Audio is decoded when loaded, so clicking a track starts playback without buffer spin-up. Monitor Mode routes a preview to private headphones before venue playback. The track editor offers a waveform, draggable in and out points, intro trimming, and player-name fields for walk-on cues. Operators can assign keyboard shortcuts, scan loudness in LUFS, flag tracks outside a target, and normalize the library in one click. The app tracks play counts and can export CSV reports for audio logs. It imports Sports Sounds Pro .set files, including banks, track names, and file paths. Playback control is available through Bitfocus Companion, a phone or tablet web remote, or OSC. It is free, with desktop and browser versions listed for macOS, Windows, and web. The maker notes that OSC is unauthenticated and that the web remote pairing URL contains a persistent token.
