Description

FFT Spectrum Audio Analyzer transforms your device into a professional-grade audio measurement system. Whether you are calibrating home theater speakers, tuning car audio systems, analyzing room acoustics, or troubleshooting sound equipment, this app delivers the precision and features that audio professionals demand. PROFESSIONAL FFT ANALYSIS Real-time Fast Fourier Transform analysis with multiple resolution options. Choose from 4096, 8192, 16384, or 32768 point FFT sizes to balance frequency resolution and response time for your specific application. Higher FFT sizes reveal fine frequency detail while smaller sizes provide faster updates for dynamic measurements. OCTAVE-NORMALIZED DISPLAY Pink noise appears flat on the display, following the standard convention used in professional acoustics measurement. This octave normalization makes it easy to identify frequency response problems and compare measurements to industry standards. FLEXIBLE SMOOTHING OPTIONS Select the level of detail that matches your needs: - 1 Octave smoothing for quick system overview - 1/3 Octave for standard acoustic measurements - 1/6 Octave for detailed speaker analysis - 1/12 Octave for crossover tuning - 1/24 Octave for precision measurements DECAY AND AVERAGING MODES Multiple visualization modes help you capture the information you need: - Time-based decay (0.5s to 8s) for live sound analysis - Peak Hold to capture maximum levels - Running Average for stable long-term measurements MEASUREMENT TOOLS - Touch cursor for precise frequency and level readout - Peak frequency tracking with automatic detection - Pinch to zoom for detailed frequency range inspection - dB scale adjustment for optimal dynamic range display SAVE AND COMPARE Store measurements for later reference and comparison: - Save unlimited spectrum graphs with timestamps - Recall saved measurements as overlay for A/B comparison - Baseline subtraction mode shows difference from reference - Rename and organize your measurement library EXPORT AND SHARE Document and share your measurements: - Export high-resolution PNG images to Photos - Generate XLSX spreadsheet files with frequency and dB data - Share via email, messaging, or cloud storage CALIBRATION Device-specific microphone calibration ensures measurement accuracy. Adjust the calibration offset to match external reference microphones or compensate for known device characteristics. EXTERNAL MICROPHONE SUPPORT Connect professional USB or Lightning audio interfaces for improved measurement accuracy. The app automatically detects and switches to external input devices. USE CASES Home Theater Setup: Measure and balance speaker levels, identify room modes, verify subwoofer integration, and optimize crossover settings. Car Audio Tuning: Analyze frequency response at the listening position, identify resonances, and tune equalizer settings for optimal sound. Live Sound: Quick system checks, feedback identification, and real-time monitoring during performances. Studio Acoustics: Room analysis, monitor calibration, and acoustic treatment verification. Speaker Testing: Frequency response measurement, driver matching, and crossover design verification. Education: Visualize sound and frequency concepts for teaching acoustics and audio engineering. DESIGNED FOR PROFESSIONALS Clean, dark interface optimized for use in low-light environments. High contrast display with cyan spectrum trace for easy visibility. Responsive controls designed for one-handed operation. No internet connection required. All processing happens locally on your device. Your audio data stays private.
