Roomtone
Read full descriptionHide full description
Roomtone is a lens that transforms the sounds around you into ambient music, in real time. Sounds picked up by the microphone are dissolved, stretched, and reshaped into a new space. The quiet of your room, rain, the hum of an air conditioner, distant voices โ ordinary surroundings become music that exists only in that moment. The same sound never plays twice. TAPE DECAY โ vast silence of a worn-out tape LABYRINTH โ folding echoes POOL โ ripples beneath the surface PRISM โ sound, refracted INNER BODY โ pulse from within RAIN DESK โ rain on your desk PROMENADE โ music for walking DEEP SEA โ pressure of the deep CHOP COLLECTOR SATOSHI โ collected fragments MANHOLE โ resonance underground LAST TRAIN โ after the last train Best experienced with headphones. Background playback supported. No recording, no storage, no transmission. No network connection. No tracking, no account, no ads.

Sphere Flow Pocket turns your iPhone into a 3D panning controller for immersive audio. Hold the glowing sphere on screen and move your iPhone through the air โ the audio object in your DAW follows in real time, at full floating-point resolution. Let go and it stays. Reach a wall and you feel it click in your hand. No MIDI mapping, no mouse. Just move. HOW IT WORKS Sphere Flow Pocket connects over your local Wi-Fi network to the free companion AAX plug-ins for Avid Pro Tools. Insert SphereReceiver on a mono or stereo track โ or SphereConstellation on a 5.1, 7.1, 7.1.2, 7.1.4 or 9.1.6 stem โ and your motion is rendered in real time while every move is recorded as plug-in automation. Plug-in instances on your network are discovered automatically and appear in a one-tap menu. Communication is built on the open ADM-OSC standard. Full setup guide and plug-in download: reminitone.com/products/sphere-flow A CONTROLLER, NOT A SCREEN Pocket is designed to be used blind. Keep your eyes on your DAW: the iPhone in your hand is the controller, and haptics tell you what you cannot see โ a tap when you grab, a knock when you hit a wall, a faint rumble as you slide along it, a click when the sphere snaps into place. Position is relative: every time you hold the sphere, the motion starts from where it is now, so you never have to reach across the room. FREE โข Mono panning โ unlimited, forever โข Haptic walls, floor and ceiling โข Wall Snap โข CENTER โ bring the sphere back to the middle of the room in one tap โข Adjustable motion range: 20 to 80 cm of iPhone travel across the full stage PRO (one-time purchase, 7-day free trial) โข Stereo โ two spheres, front and back on screen; swap targets with one tap โข Constellation โ take an entire 5.1, 7.1, 7.1.2, 7.1.4 or 9.1.6 stem as one object. Move it with your hand, turn and tilt it with your wrist, scale it with a slider or by dragging while you hold. Lock rotation or scale to protect what you have already written, reset either with one tap โข Physics โ Throw with a swipe (the sphere flies the way you were moving), Gravity, Bounce. Every bounce is felt in your hand and recorded as automation Try everything free for 7 days, then unlock once to keep it. Mono panning stays free whether or not you buy. BUILT FOR ENGINEERS โข 6DoF motion tracking โ real position in the room, not just tilt โข Float resolution over OSC โ no 7-bit MIDI stepping โข 60 Hz position updates for dense, smooth automation โข Automatic discovery via Bonjour, manual IP connection as fallback โข Tracking-loss protection: the sphere freezes instead of jumping when tracking degrades REQUIREMENTS Sphere Flow Pocket requires the free companion plug-ins (AAX, for Avid Pro Tools) running on a computer on the same network: SphereReceiver for mono/stereo tracks, SphereConstellation for 5.1, 7.1, 7.1.2, 7.1.4 and 9.1.6 stems.
