A lightweight Linux alternative to RightMark Audio Analyzer for evaluating audio files, loopback captures, and codec fidelity with precision spectral metrics. Key Features: * Precision Calibration WAV Synthesizer: Generates bit-exact 16-bit and 24-bit PCM WAV calibration signals at 44.1 kHz, 48 kHz, and 96 kHz including 1 kHz reference sine, 60 Hz + 7 kHz SMPTE twin-tone IMD, 20 Hz to 20 kHz logarithmic sweep, white noise, and dual-channel stereo crosstalk test probes. * Multi-Format Audio Decoding: Reads uncompressed PCM WAV directly and decodes FLAC, MP3, Ogg Vorbis, Opus, AAC, and M4A audio files via bundled FFmpeg into floating-point frames. * Windowed Radix-2 FFT Distortion Metrics: Applies a 4-term Blackman-Harris window with Welch spectral averaging to compute Total Harmonic Distortion (THD % and dB), THD+N (dB), Signal-to-Noise Ratio (SNR dB), Dynamic Range, Peak and RMS dBFS, Crest Factor, DC Offset, and Stereo Crosstalk (dB). * Harmonic Spectrum Plot & Lab Reports: Renders an interactive logarithmic frequency spectrum with H1 through H10 harmonic markers and exports HTML, CSV, and JSON lab reports.
