Diamond DJ Audio

Diamond DJ turns your iPad or iPhone into a complete game-day audio booth for baseball and softball. Walkup songs, inning music, the national anthem, sound effects — all on one screen, all running from songs you already own. WALKUP SONGS Assign any track from your Music library to each batter. Set a custom start time so the song jumps straight to the hook — no awkward intros. Pitchers get their own entrance music. Tap a player on the lineup screen to fire their walkup the moment they step to the plate. LINEUP THAT LIVES BETWEEN GAMES Drag-to-reorder your batting order. Tap to bench a player or swap them in. Add jersey numbers, positions, and emoji avatars. Your roster persists so you're not rebuilding it before every first pitch. BREAK MUSIC WITHOUT THE SCRAMBLE Assign a Music library playlist to inning changes, opponent warmup, game breaks, post-game wins, and post-game losses. Start break music with one tap — it plays with a countdown timer and fades out automatically when the break ends. No more digging through Apple Music while the umpire is staring at you. PRE-GAME, READY ON A TAP A dedicated screen for the national anthem, your pre-game announcement, and your warmup playlist. Pre-set everything before the team takes the field; play each one with a single tap when you need it. SOUND FX BOARD Six bundled effects out of the box — Applause, Air Horn, Charge, Drum Roll, Fireworks, Window Break — plus you can add your own from any song in your library. Use the clip editor to trim a track down to a 5-second hype moment. Customize the emoji, color, and audio for every FX card. FADES BUILT FOR LIVE SPORTS Smooth fade, hard cut, slow drop — pick the curve that fits each moment. Team defaults, per-player overrides, configurable crossfade between songs. Walkups slam in at full volume so every batter gets their hype; transitions feel professional. WORKS WITH WHAT YOU ALREADY HAVE Plays anything in your Music library, including songs you've downloaded from Apple Music. Routes audio automatically to AirPods, AirPlay, Bluetooth speakers, wired headphones, or your stadium's PA. No streaming required mid-game — songs play locally for game-day reliability.

Teams, rosters, walkup assignments, and break playlists all live on your device. No accounts, no logins, no tracking, no analytics. The app reads your Music library for playback only and never sends song information off-device. REQUIREMENTS iOS 18 or later. iPhone or iPad. Access to your Music library. An Apple Music subscription is not required — but downloaded Apple Music tracks are supported, alongside songs you've purchased or imported. Built for coaches, parent volunteers, PA announcers, travel-ball managers, and anyone who's ever had to fumble with a phone in the bottom of the seventh.
