FNam Audio & FFT Analyzer is a precision tool designed for sound engineers, researchers, students, and audio enthusiasts who need accurate frequency analysis and data logging.
■ Exclusive Features (Why FNam?)
Unlike typical sound meter apps, this app offers advanced features like Dual File Comparison and CSV Export, enabling detailed post-analysis of audio data.
■ KEY FEATURES
1. Real-time Audio Analysis
• High-precision FFT (Fast Fourier Transform) Graph.
• Time Domain Waveform (Oscilloscope) view.
• Fluid Spectrogram for visualizing frequency changes over time.
2. Dual File Comparison (Exclusive Feature)
• Simultaneous loading of two WAV files for comparative analysis.
• Spectrum Overlay: Visually compare differences using color-coded traces (Blue vs. Magenta).
• Instant Calculation: Provides Arithmetic Mean and Mean Difference between signals.
3. Data Logging & Export
• Flexible Sampling Rates: Supports various rates (4000Hz, 8000Hz, 16000Hz, 22050Hz, 44100Hz).
• High-quality Recording: Audio is recorded and saved as WAV files, strictly matching the selected sampling rate.
• Raw Data Export: Exports raw PCM data to CSV format. The exported data maintains the exact sampling rate and duration, making it optimized for post-processing in Excel, MATLAB, or Python.
• File Management: Files are stored in the 'Download\FNamDoc' directory.
- WAV naming format: Date_Time_SampleRate_Channel.wav
ex) 20260219_164715_44100Hz_Mono.wav
- CSV naming format: Selected WAV file name_SampleRate_Duration(s).csv
ex) 20260219_164715_44100Hz_Mono_44100_5.2s.csv
4. Professional Configuration
• Window Functions: Selectable Rectangular, Hann, Hamming, and Blackman windows.
• Frequency Weighting: Supports A, B, C, and Z (Linear) standard weighting filters.
• Axis Control: Supports both Auto-scaling and Manual range settings (Hz / dB) for precise graph inspection.
• Calibration: Independent offset controls for FFT and Time Domain to ensure alignment with professional reference equipment.
• Max Peak Hold: Displays and holds the maximum amplitude values across the frequency spectrum.
■ TECHNICAL SPECIFICATIONS
• Signal Processing: Anti-aliasing filters are automatically applied during downsampling to ensure measurement accuracy.
• Sampling Rate: Supports standard rates up to 44.1kHz (device dependent).
• Standards: Implements IEC 61672 formulas for accurate weighting calculations.
⚠️ Note: While this app uses IEC 61672 standard formulas, measurement discrepancies compared to professional equipment may occur due to the hardware frequency response limitations of the built-in smartphone microphone. For critical measurements, the use of a calibrated external microphone is recommended.
