A few things worth knowing.
Will my files be changed or uploaded?
No. AudioInfo Viewer reads the files you choose locally and does not modify or upload them. Files in a cloud-managed folder may be downloaded or synced by that service according to your settings.
Are my files remembered after quitting?
No. The file list and inspection results are kept only for the current session. Removing a file or clearing the list does not delete the original. Copied text remains under the control of the system clipboard.
Can it play, edit or analyze audio?
It is a metadata viewer, with no playback, tag editing, signal analysis or report export. Loudness, tempo and key shown in tags are existing metadata, not measurements calculated by the app.
