Frequently asked questions
Where is the audio file processed?
Processing runs locally in your browser. The file is not uploaded to the WaveFixer server.
Which audio formats are supported?
WAV and MP3 are the most reliable. FLAC, OGG, and other formats depend on browser support.
Do I need to install software?
No. The tool works directly on the website in a modern browser.
Is the original file preserved?
Yes. The original file on your device is not changed; the processed result is saved separately.
