Useful answers

Need help?

Will my audio be uploaded?

Your audio files are processed on your device. The browser downloads the site and engine from the host. See privacy information for temporary storage and optional services.

Can WAV restore quality lost in an MP3?

No. WAV can preserve the decoded signal without a new lossy encoding, but cannot recreate information already discarded.

Why was my file or output refused?

The actual codec, precision, layout or timing may fall outside the qualified subset. The app explains the restriction rather than silently reducing quality. See supported formats.

Does the maximum file size work on every device?

No. Limits are refusal ceilings. Browser quota and available memory may require smaller files. Physical mobile testing has not been performed for this preview.
