PolyMic
Read full descriptionHide full description
PolyMic turns your iPhones into a synchronized multi-track studio. Place a phone by each instrument, hit record, and every player gets their own clean, separated track - drums, guitar, bass, keys, etc. No audio interface. No expensive studio microphones. No laptop. No cables running across the rehearsal room. MULTI-TRACK CHANGES EVERYTHING A single phone in the corner gives you one muddy room recording. PolyMic captures each source separately, so you can mix the band's rehearsal, live set or demo recording afterwards and actually hear what your band sounds like. THREE EASY STEPS. ZERO GEAR. 1. Place your phones - one near each instrument or amp 2. Hit record - one tap starts every device at once 3. Mix and share - adjust levels and export straight from your phone PERFECTLY IN SYNC, AUTOMATICALLY PolyMic aligns every track to the millisecond on its own. No clapping to find a sync point, no dragging waveforms around in an editor, no drift halfway through the take. Press record and it just works. BUILT OFFLINE-FIRST Works anywhere. Phones connect directly to each other - no network required, so PolyMic will work even in a basement studio with no reception and no Wi-Fi. BUILT FOR - Band rehearsals and practice sessions - Jam sessions and demo recordings - Live gigs - Podcasts and interviews with multiple speakers - Music teachers and students reviewing takes MIX ON THE RIDE HOME Balance levels, pan instruments, and export a finished mix from your phone. That usual throwaway rehearsal recording turns into a demo. BUILT BY MUSICIANS PolyMic started with a familiar frustration: the best take of the night happened, and nobody caught it properly. We built the tool we always wanted - no gear budget and easy to use. HEAR THE EXAMPLES Check out PolyMic on Instagram and YouTube to hear what the recordings sound like.

ImmerGround

Turn your music into live, reactive visuals, right from your iPhone, iPad, and Mac. The whole app now speaks 15 languages. ImmerGround is a music-reactive visual instrument for musicians, VJs, DJs, producers, and performers: a music visualizer you can play like an instrument. Start from a shader or bring your own video and images, map them to audio and MIDI, and watch every beat, note, and frequency reshape the picture in real time. ImmerGround is free to start, and anyone can create projects. ImmerGround Pro, an optional auto-renewing subscription, unlocks the Pro shaders and effects, sharing, and renders up to 4K. FEATURES Shaders That Move to Your Music: 28 generative scenes, from cymatics and city skylines to ink, posters, petals, and glyph storms. Every scene has four knobs of its own, already mapped to the music, so it moves with your track from the first second. Save a look as a preset and bring it back in one tap. Your Music, in Sync: Play songs from your files or your music library, build setlists, or use the mic. Open a streaming panel in the Music sheet: it plays in its own app and ImmerGround hears it through the mic. Music keeps playing in the background. The Music Clock follows tempo and beats live, so effects and pad scenes land on the beat. On Mac, visuals can also follow music playing in any other app. Audio-Reactive in Real Time: Split the spectrum into Sub, Bass, Mid, High, and Air, or dial in your own frequency window. Full MIDI Mapping: Connect any MIDI controller and map CC knobs, notes, pitch bend, and pads to anything on screen. Built-in MIDI Learn binds a control in one move. A Rack of Effects: Pixelate, glitch slicing, RGB split, zoom pulse, strobe, and more, plus eight effect packs: Kaleidoscope, ASCII, Motion Track, Old TV, Print, Film, Flow, and Depth. Stack and modulate them into a look of your own. Precise Source-to-Effect Routing: Pick a source (a bass band, a MIDI knob, a held note), pick a destination (glitch amount, zoom, kaleidoscope sides, playback speed), and shape how one drives the other with response curves, output ranges, and smoothing. Build as many links as you like, all at once. Trigger Mode, Pad Scenes & Video Cues: Load a bank of clips and images and fire them from pads. Split a video into pads and jump to any moment with a tap, a key, or a MIDI pad. Play setlists, not settings. Multi-Layer Compositing: Stack video, image, and effect layers with blend modes and opacity. Store: Free CC0 VJ loops you can use anywhere, plus shader looks and effect packs, right on the library page. In Your Language: ImmerGround now speaks English, Deutsch, Español, Français, Italiano, 日本語, 한국어, Nederlands, Polski, Português (Brasil), Русский, Svenska, Türkçe, 简体中文 and 繁體中文. Projects That Remember: Unlimited projects, saved automatically, with undo and redo that survives across launches. Built for the Stage and the Studio: A fast, hardware-inspired interface designed for live control. Send the show to a projector or second screen over HDMI or AirPlay. Hit REC to capture your set, or render it offline up to 4K. Universal across iPhone, iPad, and Mac. From bedroom jams to club walls, ImmerGround makes expressive visual performance accessible. Bring your sound to life. SUBSCRIPTION ImmerGround Pro unlocks every Pro shader, effect pack, and loop, sharing and export, and renders up to 4K. It is available as a weekly or annual auto-renewing subscription. Payment will be charged to your Apple Account at confirmation of purchase. Your subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription anytime in your App Store account settings. SAY HI!
