Audiocopter

Audiocopter turns any song into a cave you have to fly through. Load a track and the walls ARE the sound. The kick drum punches up from the floor, snares and melody punch down from the ceiling, and the whole waveform scrolls past you in time with the music. Quiet verses open the tunnel wide; loud choruses squeeze it tight. You are not flying to the music — you are flying through it. Hold anywhere to climb, let go to fall. Forward is automatic. Your score is how far into the song you get. Crash and the track restarts. Clear the whole song without touching a wall to win it. FOUR TRACKS BUILT IN Glide, Groove, Bounce and Chug ship with the app — start flying immediately, no setup. BRING YOUR OWN Load any audio file on your device — MP3, WAV, M4A, AAC, FLAC, OGG. The song is decoded and analyzed entirely on your phone. Nothing is uploaded, nothing leaves the device. Songs you load are saved to your on-device library with your best run on each. ALWAYS BEATABLE The cave keys off frequency, not raw volume, so even brick-walled masters generate a fair course. A clear channel is guaranteed down the middle and the slope can never out-climb your helicopter. MAKE IT YOURS Pick your map color, your helicopter color, and a terrain style. Calibrate audio/visual timing once and it's remembered. No ads. No accounts. No tracking. No internet needed. Just two brothers who make games because it's fun.
