@Emmenemoi I have been using Jaffree to convert and analyse audio files without issues. Usually you can get more information about what is going on by enabling debug logging. This also prints out the command being executed, which often is the cause of the error you are seeing.

You can also set a breakpoint here and see what command is executed

Jaffree/src/main/java/com/github/kokorin/jaffree/process/ProcessHandler.java

Line 77 in b69f08e

LOGGER.info("Command constructed:\n{}", joinArguments(command));

This is what I have added to my log4j config to enable logging

        {
          "name": "com.github.kokorin.jaffree",
          "level": "debug",
          "additivity": "false",
          "appender-ref": [
            {
              "ref": "File-Appender"
            }
          ]
        },

Hope that helps in finding the cause of your issue

Yes, sorry. After enabling debug logging i found the problem in the progress handler...
