FFT Analyzer

FFT Analyzer is a real-time spectrum analyzer for iPhone featuring a large FFT display, dedicated waveform monitoring, and RMS / peak readouts.

The app is built for precise visual audio monitoring and includes extensive setup options for spectrum behavior, level response, and visual tuning. Available parameters include frequency bands, smoothing, peak hold, peak decay, frequency axis, auto dB scaling, frequency and dB range, waveform auto scaling, and time window configuration.

For signal evaluation, the app uses a custom-developed analysis algorithm that has been AI-assisted in its optimization for detection, smoothing, and display behavior.

FFT Analyzer is intended for users who need a technically oriented and highly configurable real-time audio analysis tool on iPhone.
