Add files, then submit
Batch mode is designed for reviewing several tracks together. Selecting files adds them to the queue without starting analysis. Check the filenames, then use the button showing the number of selected tracks.
Single-track mode is different: adding a file starts analysis immediately. Both modes are free, with no account, subscription or daily/monthly track quota.
Follow each track’s result
The analysis dialog shows the active track and completed-track count. Results appear as tracks finish. You can close the dialog while analysis continues in the page and open it again from the progress or results button.
Errors are displayed for the relevant file. A file that cannot be decoded is not a result. Service-wide availability or rate limits may stop a run; review the displayed status before retrying.
Keep the CSV if you need a record
CSV export is free and generated in your browser from completed results in the current page. It includes filenames, verdicts and model output, and escapes spreadsheet formula-like filenames. It is not a certificate of authorship or a legal report.
Download before clearing the file list or leaving the page. Suno Checker has no saved result history to restore later. Email registration is not required for export.
Input and processing limits
Each file must be MP3, WAV, FLAC or M4A, 15 seconds to 10 minutes long and within the 100 MB upload limit. The browser prepares up to 30 seconds of audio for each analysis.
No track-count subscription limit applies. Requests are still subject to operational rate and concurrency protections, and the queue processes files sequentially.
