Frequency Analyzer Spectrum vs Frequency Generator App

Frequency analyzer for musicians, audio engineers, and the audio-curious. Frequency Analyzer turns your iPhone into a complete real-time audio toolkit — see exactly what frequencies are in any sound, in true engineering accuracy, with zero setup. LIVE SPECTRUM The live audio spectrum analyzer paints every frequency from 20 Hz to 20 kHz, frame by frame, so you can watch sound move. Switch to Waterfall view to see frequency content evolve over time — perfect for hunting down a buzz in your room or finding the resonant frequency of a speaker. Tap any peak to lock a marker on it. As a pure spectrum analyzer it shows you the dominant tone in big, easy numbers. PITCH METER Need to know exactly what note you're playing? The pitch meter is a high-precision frequency meter that detects any frequency in Hz with cents-of-a-semitone accuracy. Built-in tunings for guitar, bass, ukulele, and violin. Use it as a chromatic tuner, a vocal tuner, or just as a pure sound frequency analyzer when you need to identify a tone in the air. LOUDNESS METER Switch the meter into Loudness mode and Frequency Analyzer becomes a calibrated decibel meter with A-weighted, C-weighted, or Z-weighted readings — the same modes you'd find on a professional sound level meter. Track peak and average dB across a session. Use it to check whether your room is too loud, your gear is too hot, or the office really does need a quieter coffee machine. TONE GENERATOR The built-in tone generator covers 20 Hz to 20 kHz with sine, square, triangle, and saw waveforms. Send any frequency to your speakers in seconds — handy for testing studio monitors, finding speaker rattles, referencing a pitch, or feeding a signal into the spectrum analyzer for calibration. LOG SWEEP The log frequency sweep slides smoothly from 20 Hz to the top of human hearing in 5, 15, 30, or 60 seconds. Pair it with the audio spectrum analyzer in another room to find weak driver frequencies, sympathetic resonances, or "the one" buzz that's been driving you mad. HEARING TEST The 8 kHz to 20 kHz hearing test tells you the highest frequency you can still hear and gives a quick age-related estimate. Use headphones for accurate results. RECORD AND REPLAY Capture 10 seconds of audio at any time. The replay engine plays it back through the same FFT pipeline so you can analyze the frequency content of a moment that already passed — replay it in the audio frequency analyzer view at full resolution. SESSIONS Every analysis session is saved automatically — dominant frequency, min, max, average, peak dB. Look back at what your room sounds like, how high you sang, or how loud last night really was. WHY FREQUENCY ANALYZER • Pure audio engineering accuracy — Hann-windowed FFT at 44.1 kHz • Real-time, low-latency rendering • Works fully offline, no account, no subscription, no ads • Clean, focused dark UI built for the iPhone • Five tools in one frequency analyzer: spectrum, meter, generator, sweep, hearing test

Audio Frequency Generator The Audio Frequency Generator app allows users to explore the world of sound waves and frequencies with precision and ease. Designed for enthusiasts and professionals alike, this app offers a variety of tools to generate sound tones and frequencies, including the popular 432Hz frequency. Key Features: Tone Generator: Create pure tones by adjusting the frequency from a wide range of Hz (Hertz), ideal for sound testing, meditation, or tuning instruments. Frequency Sweep Generator: Generate smooth transitions between selected frequencies over a specified duration. Perfect for sound testing and experimentation. Presets: Easily access pre-configured sound settings for relaxation, focus, meditation, and sleep. You can also customize and save your own presets with specific frequencies and wave types. Binaural Beats Generator: Generate soothing binaural beats by adjusting the base frequency and beat frequency to create a meditative audio experience. SFX (Sound Effects) Generator: Play around with sound effects like beeps, chirps, buzzes, and alarms, allowing you to experiment with different sound waves for creative purposes. Sleep Timer: Use the sleep timer as a simple countdown tool to track the duration of your sessions. Additional Features: Adjustable frequency ranges from low (100 Hz) to high (1000 Hz) for a variety of sound experiences. Waveform selection: Choose from different wave types such as sine, square, and more, to modify the sound texture. Volume control and easy-to-use sliders for precision adjustments. Whether you're experimenting with sound waves, using hz frequencies for relaxation, or creating custom tones for specific purposes.
