🌊 songsee — FFT so pretty, your ears will be jealous.\n\n![9-mode visualization example](example.png)\n\n## Features\n\n- **9 visualization modes**: spectrogram, mel, chroma, hpss, selfsim, loudness, tempogram, mfcc, flux\n- **6 color palettes**: classic, magma, inferno, viridis, gray, claw\n- **Auto-contrast**: per-panel percentile normalization for readable heatmaps\n- **Combine modes**: stack multiple visualizations in one grid image\n- **Universal input**: WAV, MP3, or anything ffmpeg can handle\n- **Fast**: native Go, no Python dependencies\n- **Flexible output**: PNG or JPEG, customizable dimensions\n\n## Install\n\n```bash\nbrew install steipete/tap/songsee\n```\n\n```bash\ngo install github.com/steipete/songsee/cmd/songsee@latest\n```\n\n## Quick Start\n\n```bash\n# Basic spectrogram\nsongsee track.mp3\n\n# Mel spectrogram with magma palette\nsongsee track.mp3 --viz mel --style magma\n\n# All 9 modes combined\nsongsee track.mp3 --viz spectrogram,mel,chroma,hpss,selfsim,loudness,tempogram,mfcc,flux\n\n# Custom output\nsongsee track.mp3 --viz hpss,chroma --style inferno -o viz.png --width 2560 --height 1440\n```\n\n## Visualization Modes\n\n| Mode | Description |\n|------|-------------|\n| `spectrogram` | Time × frequency magnitude |\n| `mel` | Perceptual frequency scale |\n| `chroma` | 12-bin pitch class |\n| `hpss` | Harmonic vs percussive separation |\n| `selfsim` | Self-similarity matrix |\n| `loudness` | Volume over time |\n| `tempogram` | Tempo variation |\n| `mfcc` | Timbre fingerprint |\n| `flux` | Spectral change detection |\n\n## Palettes\n\n`classic` · `magma` · `inferno` · `viridis` · `gray` · `claw`\n\n## Options\n\n```\n--output        Output path (default: input name + extension)\n--format        jpg or png (default: jpg)\n--width         Output width (default: 1920)\n--height        Output height (default: 1080)\n--window        FFT window size (default: 2048)\n--hop           Hop size (default: 512)\n--min-freq      Minimum frequency in Hz\n--max-freq      Maximum frequency in Hz\n--start         Start time in seconds\n--duration      Duration in seconds\n--style         Palette name\n--viz           Visualization list (repeatable or comma-separated)\n```\n\n---\n\nBuilt by
