What problem does it solve? Analyzing audio content visually requires specialized tooling; this Skill turns audio files into spectrograms and multi-panel feature visualizations (mel, chroma, MFCC, and more) with a single CLI command, making audio structure, tempo, and onsets inspectable as images. ## Core Features & Use Cases - Spectrogram Generation: Render standard or mel-scaled spectrograms from WAV and MP3 files, with optional ffmpeg support for other formats. - Multi-Panel Feature Grids: Combine up to nine visualization types (chroma, HPSS, self-similarity, loudness, tempogram, MFCC, spectral flux) into a single image. - Time Slicing & Styling: Extract specific time ranges with --start/--duration and customize output with color palettes, dimensions, and frequency filters. - Use Case: Compare two synthesized audio outputs by generating side-by-side mel spectrograms, then inspect the images with vision_analyze to verify the synthesis pipeline. ## Quick Start Ask the agent to generate a mel spectrogram and chroma visualization grid from your audio file, saved as a PNG image.
