Signal Generator - Tone Audio
Frequency and Sound Test Tool
$4.99 · Designed for iPad. Not verified for macOS.
Generate precise audio signals for professional testing. Perfect for audio engineers, musicians, and acoustics work. Sine, square, white noise, and pink noise waveforms.
PROFESSIONAL AUDIO SIGNAL GENERATION
Signal Generator transforms your iPhone and iPad into a professional-grade audio signal generator. Create laboratory-accurate sine waves, square waves, white noise, and pink noise from 20Hz to 20kHz with precision and reliability.
Whether you are an audio engineer testing speakers, a musician tuning instruments, a sound technician calibrating equipment, or a home theater enthusiast optimizing your setup, Signal Generator delivers the accuracy you need.
PRECISION WAVEFORMS
Generate four essential waveform types with laboratory accuracy:
- Sine Wave: Pure tonal frequencies for precise audio testing
- Square Wave: Rich harmonic content for equipment testing
- White Noise: Full spectrum noise for acoustic analysis
- Pink Noise: Balanced spectrum for room calibration and speaker testing
INTUITIVE FREQUENCY CONTROL
Navigate the entire audible spectrum with smooth, glitch-free control:
- Frequency Range: 20Hz to 20,000Hz
- Three Resolution Modes: Octave, 1/3 Octave, and Fine (1Hz steps)
- Direct Entry: Tap to enter any exact frequency
- Smooth Transitions: No clicks or pops when changing frequencies
PROFESSIONAL FEATURES
- Channel Routing: Output to stereo, left only, right only, or inverted right for pseudo-balanced testing
- Wobble Mode: Warble-tone generation for acoustic measurements and room analysis
- Octave Band Noise: Band-limited pink and white noise for targeted frequency testing
- Background Audio: Continue signal generation while using other apps
- Soft Mute: Gentle fade to prevent speaker damage from sudden stops
REAL-TIME VISUALIZATION
Watch your waveforms come to life with a real-time oscilloscope display. See exactly what signal is being generated and verify your output visually.
SAVE YOUR SETTINGS
Create and save unlimited presets for quick access to your most-used configurations. Perfect for standardized testing procedures or frequently used calibration tones.
