UAP Whistle
Universal Audio Pilot
$4.99
New in 4.1: a complete redesign as a professional signal mixer. Combine tones, sweeps, noise and binaural beats and verify each frequency with the live spectrum analyzer.
UAP Whistle – Universal Audio Pilot – is a precision signal generator and mixer for your Mac. Build your own audio signals from ready-made layers or from scratch, mix them like on a studio console and verify every frequency with the built-in oscilloscope and spectrum analyzer.
BUILT LIKE A MIXING CONSOLE
Every signal gets its own channel strip: live waveform preview, parameters, pan, mute and solo, plus a level fader in dB with a stereo meter. A master section with soft limiter keeps the mix clean. Up to 24 channels.
SIX SIGNAL TYPES
• Tone – sine, triangle, square or sawtooth from 0.5 Hz to 22 kHz
• AM Tone – carrier with adjustable modulation rate and depth
• Binaural – separate left and right frequencies for binaural beats
• Noise – white, pink or brown, with optional slow "breath" modulation
• Pulse – tone bursts with exact length and interval, optionally randomized
• Sweep – linear or logarithmic, single-shot or continuous loop
READY-MADE SIGNALS
Pilot Tone 1.6 kHz, Schumann Resonance (7.83 Hz), Solfeggio 528 Hz, Ambient 432 Hz, Ultrasonic Ping 17 kHz, Organic Chirp, Breath, Pink Noise, Reference 1 kHz, Sine Sweep 20 Hz–20 kHz, Low-Frequency Test 7.83 Hz and Binaural Alpha 10 Hz – or create your own with any frequency you need.
PRECISION YOU CAN MEASURE
• 64-bit phase accumulators keep frequencies exact, even during long sessions
• Sample-accurate timing for pulses and sweeps
• Band-limited oscillators – no aliasing on square and sawtooth waves
• The fader value equals the output level in dBFS
• Type in every value precisely: frequency, time, depth or level
• Smooth, click-free start, stop and parameter changes
SEE WHAT YOU HEAR
The visualizer analyzes the real output signal: a triggered oscilloscope with selectable time window and a live spectrum analyzer with exact peak frequency and level readout – ideal for checking and calibrating your setup.
SCENES & RECORDING
• Demo scenes to start instantly: Signal Demo, Schumann Meditation, Alpha Focus, Calibration 1 kHz −20 dBFS, Resonance Sweep and Low-Frequency Test
• Save your own mixes as scenes, import and export them as files
• Your last session is restored automatically
• Record the output as WAV (24-bit, stereo)
MADE FOR
Sound engineers, acousticians and engineers testing rooms, speakers and resonances – and anyone who wants to create calming soundscapes with Schumann, Solfeggio and binaural frequencies.
GOOD TO KNOW
• Very low frequencies such as 7.83 Hz are infrasound and cannot be reproduced by most speakers. The Schumann channel therefore applies 7.83 Hz as an amplitude modulation to an audible carrier.
• Binaural beats require headphones.
• Please protect your hearing and start at a low volume. High-frequency signals may be unpleasant for pets.
• UAP Whistle is an audio tool, not a medical device.
Available in English and German.
