Read full descriptionHide full description
Waveguide Flute turns your iPad or iPhone into a physically modeled wind instrument — a Cook/STK-style waveguide flute you play from an on-screen piano roll or a MIDI wind controller (EWI). FEATURES • Authentic waveguide physical modeling — not a sample library • Deep Sound page: shape jet ratio, reflection, loop damping, noise, and more • Expression controls for live performance: blow intensity, breathiness, pitch bend, auto-vibrato • Built-in reverb with 7 factory spaces • On-screen piano roll with velocity and breath control • Full MIDI support — notes, breath (CC#2), pitch bend • Compatible with Akai EWI and other MIDI wind controllers that send breath and pitch bend • Remembers your last settings, with one-tap reset to defaults • Bluetooth MIDI support, plus a configurable Breath Control input (Mod Wheel or custom CC) for keyboard players without a wind controller Play it like a real wind instrument: breathe into the sound, bend pitch, add vibrato — all rendered by a genuine physical model, not recordings.

WorldSounding gathers the music of the WorldMusic series into one app. Listen to each piece, play it with your fingers, and layer several at once. Sounds are synthesized on the spot or stretched from their material, so the performance never repeats. - WorldTuning — an eternal drone that begins with an orchestra tuning up. - WorldShifting — timeless minimal music in which repeating short patterns drift apart and overlap. - WorldWandering — infinite granular music that stretches sound to extremes and repeats short fragments. - WorldRushing — harsh music in which a beautiful melody drifts through one mass of layered, distorted roar. The bar at the top shows every piece and whether it is sounding. Tap a name to bring it to the screen, where you can also change the performance. A piece keeps playing when it is not on screen, and there is no limit on how many can sound together. Turn on Dual Display to show two pieces at once. You can also fit layered pieces together. Each piece can match a shared tempo and a shared pitch, and follow the chord tones of another piece. Every piece switches these on and off on its own, and notes that do not agree can bring surprises. Each piece keeps its own screen: touch the picture to travel, shape the sound in the Sound sheet, and let it wander on its own. Send the sound to Bluetooth speakers, AirPlay speakers such as HomePod, or a USB audio interface, and control everything from Control Center and the Lock Screen. Record exactly what you hear, every piece together, as a 48 kHz / 24-bit WAV file. The built-in microphone can also listen to the sounds around you. The app analyzes them and makes the result the reference pitch of the performance. The sound is analyzed on this device: nothing is recorded, and nothing is sent. While Listening is on, AirPlay speakers cannot be chosen. WorldSounding is free with a banner ad, and every feature, including the Sound sheet and settings, is available. A piece you have not bought plays for three minutes each time you open the app. Each piece is a one-time in-app purchase that removes the limit for that piece, and buying any one removes the ad. The 4-Piece Set also lets you buy all four together.

Verdict
The clearest difference is in-app purchases: Waveguide Flute at none against WorldSounding's 5. Waveguide Flute also leads on ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
