Audio feature comparison

Upload two mono or stereo files supported by ffmpeg. The app analyzes MFCCs, stereo phase coherence, the breath heuristic, and exploratory jitter/shimmer, then produces a comparison report.

Need to analyze multiple pairs? Use the batch workflow.

Each upload is limited to 100 MB. Source audio is held only for the duration of analysis; generated reports are kept in memory for one hour and can be downloaded as JSON.
