About This Tool

This tool analyzes uploaded audio to produce objective metrics across time and frequency domains. It supports mono and stereo inputs and outputs structured results suitable for integration into data pipelines.
Conceptually, it splits audio into overlapping frames, applies a Hann window, and computes time-domain metrics (RMS, peak, loudness proxy) and frequency-domain metrics (FFT-based spectral centroid, bandwidth, spectral flux).
Unique value: batch processing, per-channel analysis, parameterized windowing, and export formats; use cases include quality assurance in hardware tests, spectral analysis in music research, and quick benchmarking across takes or versions. Core features include per-file and per-channel reports, JSON/CSV exports, and data-ready arrays for downstream analytics; outputs include per-frame metrics and concise summaries. The tool adheres to standardized definitions to ensure comparability across tools and environments, while remaining flexible for engineering and research workflows.

Review outputs: inspect per-frame metrics and per-channel summaries.
Export results: download JSON or CSV for integration.

Frequently Asked Questions

Find Quick Answers

What data formats are supported?

The tool accepts common PCM-like formats such as WAV and FLAC up to high sample rates; inputs are auto-detected for channels and duration, with outputs provided in JSON or CSV for easy ingestion into analysis pipelines.

Can it process stereo audio?

Yes. It analyzes each channel independently when requested, providing per-channel RMS, spectral features, and a combined summary; users can also opt for a summed mono analysis if preferred.

Is the analysis deterministic across runs?

Yes. With fixed inputs and parameters, results are reproducible across environments; minor differences may occur if floating-point operations vary, so exporting a fixed parameter profile ensures traceable results.

How can I use the exported data?

Exported JSON or CSV data can feed machine learning models, dashboards, or reporting tools; a compact summary is available for QA and version comparisons, while full per-frame data supports in-depth analysis.
