SYSTEM DOCUMENTATION & REQUIREMENTS

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 command, making audio structure, pitch, 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 grid image. - Flexible Output Control: Slice audio by start time and duration, choose color palettes, set image dimensions, and output PNG or JPG. - Use Case: Compare two synthesized audio outputs by generating mel spectrograms of each, then inspect the images with vision analysis to verify frequency content and detect artifacts. ## Quick Start Use the songsee skill to generate a mel spectrogram of track.mp3 and save it as spectrogram.png.

Frequently Asked Questions about songsee

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a spectrogram from an MP3 file?▼

Run songsee with the audio file as argument, for example songsee track.mp3, and use -o to set the output image path. WAV and MP3 are decoded natively without extra tools.

What audio visualization types does songsee support?▼

songsee supports nine types via the --viz flag: spectrogram, mel, chroma, hpss, selfsim, loudness, tempogram, mfcc, and flux. Multiple comma-separated types render together as a grid in one image.

Does songsee support audio formats other than WAV and MP3?▼

WAV and MP3 are decoded natively by songsee. For other formats such as FLAC or AAC, you need ffmpeg installed so the audio can be converted before visualization.

How do I visualize only part of an audio file?▼

Use the --start and --duration flags to select a time slice, for example songsee track.mp3 --start 12.5 --duration 8 to render an 8-second segment beginning at 12.5 seconds.

Can songsee read audio from stdin?▼

Yes, pipe audio data with a dash as the input, such as cat track.mp3 | songsee - --format png -o out.png. This is useful when chaining with other command-line audio tools.
