Audio Analyzer Tool

The Audio Analyzer Tool processes an uploaded audio file to produce objective metrics such as tempo, duration, loudness, and spectral features. It is designed for researchers, educators, audio engineers, and content creators who need repeatable measurements to compare recordings, validate processing pipelines, or illustrate concepts in class.
The tool uses signal processing to convert to a standard sample rate, apply mono conversion when needed, and compute per-frame metrics across overlapping windows. Tempo is estimated via onset strength and autocorrelation; spectral features include centroid and bandwidth derived from FFT, while loudness is computed from short-term energy or LUFS-based scales. Outputs include a summary per file and an optional time-series matrix for deeper analysis.
Batch processing and configurable parameters are available for batch QA and teaching demonstrations, with CSV/JSON export to feed spreadsheets or notebooks. This combination of features provides a practical, low-friction workflow for quick analytics and reproducible results. Use cases include evaluating podcast episode loudness consistency, comparing recording conditions in a lab, or illustrating DSP concepts in coursework.
