Description
On a number of files in my library, tone takes an excessively long time... 45 minutes or more. The files aren't unusually large, and size doesn't seem to be a predictor. I tried running tone with --debug but there was no additional data that was presented. For most of my library, it takes only a few seconds per file.
Are there some additional flags or tips you can suggest to help troubleshoot this problem? I thought it might be a corrupt m4b, but I've gone back and re-encoded using m4b-tools and the result is the same.
