よくある質問
Quick answers.
›What audio formats can I use?
The tool supports any format your browser can decode, including `MP3`, `WAV`, `OGG`, and `M4A`. Encrypted or proprietary formats may not render correctly.
›Are my audio files uploaded?
No. The waveform is generated using your browser's Web Audio API. Your files remain on your device and are never sent to our infrastructure.
›Can I customise the appearance?
Yes. You can adjust the foreground and background colours, as well as the bar width and spacing to change the density of the visualization.
›What is the output format?
The tool exports the waveform as a transparent or solid background `PNG` file. This allows you to easily overlay the waveform on top of other designs.
