FAQ
Can I use the PNG for social posts or podcast art?
Yes. Choose 1080×1080 or 1920×1080, set your brand colours (or a transparent background) and download.
What do peak and RMS mean?
Peak is the loudest single sample (0 dBFS is the maximum before clipping). RMS is the average energy, closer to perceived loudness.
Is the audio uploaded?
No — it's decoded and drawn locally in your browser.
