## URL patterns

- Tool landing (upload here): `/mp3-audio-waveform-graphic-generator/` · `/dj-audio-wallpaper-generator/` · `/audio-spectrogram-creator/` · `/audio-waveform-animated-gif-creator/`
- Options (per upload): `/mp3-audio-waveform-graphic-generator/options/<id>/` (spectrogram: `/mp3-audio-spectrogram-graphic-generator/options/<id>/`, gif: `/mp3-audio-animated-gif-graphic-generator/options/<id>/`)
- Download: `/mp3-audio-waveform-graphic-generator/download/<waveform|wallpaper|spectrogram|animatedgif>/<id>/`
- Public share page: `/mp3-audio-waveform-graphic-generator/share/<waveform|wallpaper|spectrogram|animatedgif>/<id>/`
- Where `<id>` is the 64-char sha256 hex id of an upload/creation.

## How it works

1. Pick a tool and upload an audio file (MP3, M4A or WAV, up to 50MB).
2. The file is converted server-side (ffmpeg) and you choose options (size, colours, spectrogram style, wallpaper template/title, animation type).
3. Your finished graphic is ready to download in seconds, with a public share page.

## Data & privacy notes

- No accounts, no signup, no personal data collected.
- Uploaded audio is kept briefly (intermediate wav ~1 day, uploaded mp3/m4a ~2 days) and generated graphics are purged after 30 days — share links stop working once a creation expires.
- All processing is done by ffmpeg/wav2png on the site's own servers.
- The site is free to access (AdSense-supported).
