Frequently asked questions
Are my audio files uploaded?
Never. Your file is decoded and processed with the Web Audio API directly in your browser. It never touches a server — processing even works offline.
What formats can I upload and download?
Upload anything your browser can play: MP3, WAV, OGG, M4A/AAC and FLAC in most browsers. The processed result downloads as a high-quality WAV file.
Is it really free? Any length limit?
Completely free with no watermark. There is no hard length limit — a typical 3-5 minute song processes in seconds; very long files just need more memory.
