DroneTone vs Arc & Decay

This app plays sustained, hand-tuned drone notes that fill the room with deep ambient resonance. Pick any pitch across the full chromatic range and hold it as long as you need — no loops, no seams, just a perfectly steady note with warm overtones. Blend waveforms, soften the attack, and dial in detuned layers to shape the texture. Set a gentle fade timer and let a single tone carry you into stillness. Background audio, AirPlay, and headphones — your drone keeps glowing wherever you go. Perfect for meditation, breathwork, deep focus, sleep, and musical practice or tuning. — SUBSCRIPTION — Premium unlocks all features. Payment is charged to your Apple ID at confirmation of purchase.

Arc & Decay is a plasma arc distortion instrument for iOS, built on the physics of real xenon gas tube breakdown. Feed it any sound through the built-in microphone and it fires an electrical arc when your signal crosses the ionization threshold. The arc saturates and distorts with odd harmonics, crackles through marginal-zone sputter, and holds a long ionization tail that decays into electrical noise long after your sound stops. Six precision encoders control every dimension of the arc character: Voltage drives the current into the gap. Ignition sets the threshold. Instability introduces chaos and arc wander. Fizzle and Spark shape the crackle density and tail length. Mix blends dry signal with pure arc output. Reverb and delay extend the electrical space without losing the character. Record up to one minute of output and share directly from the app. Arc & Decay is not a guitar pedal. It is not a synthesizer. It is a plasma arc instrument that runs on whatever sound you give it. © 2026 Synthetic Pulse Industries.
