teraFFT

clean & precise Audio Spectrum Analysis
teraFFT transforms your iPad or Mac into a professional-grade audio spectrum analyzer. Designed for engineers, musicians, and acousticians, this app provides detailed and accurate real-time FFT analysis of audio signals.
Key Features:
Real-time Spectrum Display: Visualize live frequency spectrum with minimal latency.
Configurable FFT Settings: Adjust buffer size, select window functions (Hanning, Hamming, Blackman, Flat-Top), and set overlap factors for precise analysis.
Frequency Weighting & Slope: Apply A- or C-weighting and various slope options (e.g., +3dB, +6dB per octave) to tailor spectrum visualization.
Flexible Display Ranges: Customize frequency (Hz) and amplitude (dBFS) ranges to focus on relevant data. dBFS scale can be toggled on/off.
Dual-Channel Analysis: Compare live and reference signals simultaneously. Utilize the difference display mode for clear deviation visualization.
Intelligent Peak Tracking: Identify and display the highest peak in live or reference signals, including precise frequency, note name, and cent deviation.
Adjustable Concert Pitch: Set a custom A4 reference frequency (e.g., 415 Hz, 440 Hz, 442 Hz) for accurate note calculations.
Interactive Cursor: Use a responsive mouse cursor (Hover or Replace mode) for detailed readings at any point on the spectrum.
Optimized for Mac, iPad & iPhone: Seamless cross-platform experience with adaptive UI for both portrait and landscape orientations on iPad.
teraFFT is an intuitive tool for acoustic measurements, instrument tuning, audio system calibration, and in-depth sound analysis.
