Audio to PNG Converter

This tool produces a PNG visualization from an audio file, enabling consistent asset generation for media and education workflows. It supports two visualization modes: waveform for time-domain amplitude and spectrogram for time-frequency content. The process is deterministic and repeatable, using fixed palettes and image dimensions to ensure uniform results across runs. Outputs are standard PNG images suitable for thumbnails, reports, presentations, or social media posts. By separating rendering logic from input handling, the tool scales from a single file to batch workflows without loss of visual fidelity.
