Common Questions Before Reaching Out
Processing failed or took too long? Most songs complete within a few minutes. If a paid job fails, minutes are refunded automatically. If the issue persists, include the file name and approximate upload time in your message so we can look into it.
Need a refund? Unused paid minutes are non-refundable but never expire. If a processing job produced unusable results, reach out and we will review the case.
How are free and paid minutes used? Daily free minutes are used first and reset at the end of the day. Paid Minute Pack minutes are used after free minutes and never expire.
Which audio formats work? MP3, WAV, M4A, AIFF, AIF, and FLAC uploads are supported. Output can be MP3, WAV, or FLAC based on the format you choose before processing.
Is my uploaded music private? Yes. Uploaded files and processed results are stored temporarily and are not shared, indexed, or used for training. See our Privacy Policy for details.
How do audio minutes work? Minute Pack billing rounds up to the next full audio minute. A 3:42 song uses 4 audio minutes. All stem types, online controls, and supported exports are included per processed song.
