Binaural beats for focus. A pure tone for tuning, a sweep for hearing checks, pink noise for ASMR — ToneLab Generator covers the whole 20 Hz to 20 kHz audio range across nine precision modes.

WHAT YOU CAN DO

• Sleep better with brown, pink, or white noise — the same sounds rain machines and white noise apps play, generated cleanly on your phone with no compression artifacts.
• Reduce tinnitus discomfort with a tunable masking tone. Dial in the frequency that matches your tinnitus and use sound therapy techniques recommended by audiologists.
• Focus deeper with binaural beats. Set a carrier frequency and a beat frequency in the alpha, theta, or delta range for meditation and concentration.
• Test your hearing with frequency sweeps from 250 Hz to 8 kHz — a simple at-home check before you book the audiologist.
• Tune your instrument. A 440 Hz, every chromatic note, with cents-accurate display.
• Test speakers and subwoofers across the full range. Find buzz, distortion, and frequency response issues.
• Generate isochronic tones for relaxation and modulated signals (AM, FM, PWM) for sound design.

NINE MODES

• Tone — single-frequency sine, square, triangle, or sawtooth wave at any frequency from 20 Hz to 20 kHz.
• Dual Tone — two independent tones mixed with control over the mix ratio.
• Binaural — different frequencies in left and right ears (headphones required) for binaural beats.
• Sweep — frequency glide between any two points, one-way or oscillating.
• Noise — white, pink, brown, blue, violet, grey, or velvet noise.
• DTMF — the touch-tone dial pad frequencies.
• Isochronic — gated pulses at brainwave-target rates for meditation.
• Modulation — AM and FM modulation with adjustable LFO rate and depth.
• PWM — pulse-width-modulated signals for sound design.

POWER USER FEATURES

• Save your settings as named presets. Twelve built-in presets ship with the app covering sleep, tinnitus, focus, tuning, hearing checks, speaker testing, studio reference, vintage modulation, and ASMR.
• Export any tone, noise, or signal as a 44.1 kHz / 16-bit WAV file. Share directly to other apps.
• Sleep timer with fade-out so the audio winds down gracefully when you fall asleep. Up to 8 hours for overnight use.
• Real-time waveform analyzer with FFT spectrum view.
• Harmonics control — add overtones to any waveform.
• Background audio that survives the screen turning off, with a persistent playback notification you can stop from the lock screen.
• Headphone-unplug auto-pause and phone-call audio focus handling.
• Home-screen long-press shortcuts for Brown Noise, Binaural Focus, and A 440 Hz.
