Tonscape: Frequency Generator
Tones, noise & binaural beats
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Generate any audio frequency your iPhone can produce to 0.01 Hz then watch the built-in spectrum analyzer confirm it through the mic. Tone generator + signal analyzer
Tonscape is a precise sine-wave tone generator and real-time spectrum analyzer in one clean app.
Dial in any frequency your iPhone can actually produce — from 0.01 Hz up to the hardware Nyquist limit (around 24,000 Hz) — typed to two decimal places or swept with a logarithmic slider. Set the exact pitch you need, control the volume up to full output, and play a pure, continuous sine tone.
Then prove it. The built-in microphone spectrum analyzer captures sound in real time and shows you the full frequency spectrum on a live, neon display. A single-frequency detector measures the exact level at any frequency you choose, and a noise-floor comparison tells you whether that frequency is genuinely present above the background — even faint signals buried in noise, thanks to spectral averaging.
WHAT YOU CAN DO
- Generate exact frequencies to 0.01 Hz, only the ones your device can truly produce
- Adjust volume from silent to full power
- See a live, averaging FFT spectrum analyzer with peak-hold
- Tap the spectrum to probe any frequency independently of the tone you're playing
- Get a clear "present / not detected" readout with dB-over-noise
- Identify your iPhone model and its estimated speaker range
RELAX & SLEEP (Pro)
- Binaural beats and isochronic tones with brainwave-band presets (delta, theta, alpha, beta)
- White, pink, and brown noise generators
- Nature sounds: ocean, rain, wind, stream, campfire
- Sleep timer with gentle fade-out, plus background playback so it keeps going with the screen off
- One-tap presets: Schumann/earth resonance, Solfeggio, and tuning references
SOUND DESIGN (Pro)
- Sine, square, triangle, and sawtooth waveforms
- Chords and a logarithmic frequency sweep
GREAT FOR
- Sleep, relaxation, focus, and meditation soundscapes
- Testing speakers, headphones, and subwoofers
- Checking whether a specific frequency is present in a room or signal
- Audio education, tuning references, and equipment checks
Note: binaural beats require headphones. Labels for resonance/Solfeggio presets are descriptive only — the app makes no medical or therapeutic claims. Tiny phone speakers roll off at very low and very high frequencies, so some tones may be inaudible through the built-in speaker even though the signal is generated correctly — use headphones or external speakers for the full range.
