Spectrum Analyzer+ FFT transforms your iPhone into a professional audio frequency analyzer. Using the built-in microphone, it visualizes sound frequencies in real time with a detailed FFT spectrum display. The analyzer captures live audio through the microphone and breaks it down into individual frequency bands, showing the amplitude of each frequency from 20 Hz to 20 kHz. Note: This app analyzes audio in real time for visualization purposes only — it does not record or store any audio. Key Features: - Real-time FFT audio spectrum visualization via microphone - Frequency range from 20 Hz to 20 kHz - Peak frequency detection with Hz display - Average dB level per frequency band - Adjustable dB range for detail viewing - Smooth animated bar display - Dark theme optimized for readability Whether you're a musician tuning instruments, an audio engineer checking room acoustics, or a sound enthusiast exploring frequencies, Spectrum Analyzer+ gives you a powerful visualization tool in your pocket.
