Common Issues
File upload fails
Make sure your file is under 2 GB and in a supported format. Audio: MP3, WAV, AAC, M4A, OGG, OPUS, FLAC, AIFF. Video: MP4, MOV, AVI, MKV, WebM.
Conversion takes too long
Conversion time depends on file size. Large files (over 100 MB) may take a minute or two. If it seems stuck, try refreshing and uploading again.
Download doesn't start
Check that your browser isn't blocking downloads. You may need to allow downloads from this site in your browser settings.
AI repair not working as expected
AI repair works best on speech and voice recordings. For heavily distorted audio or music with complex arrangements, results may vary. Try adjusting which repairs are applied using the checkboxes.
Audio sounds different after loudness normalization
Loudness normalization adjusts the overall volume to meet platform standards. Use "Linear" mode for music to preserve dynamics, or "Dynamic" mode for speech/podcasts for more consistent volume throughout.
