Message

MF_E_INVALIDSTREAMNUMBER - The stream number provided was invalid.

Description

This error code is shown when you try to play or edit a sound file, that cannot be decoded.

Solution

The sound file, that you tried to play or edit, has the ending mp3, m4a or one of the other supported formats, but the actual content of the file is another not supported format.

To be able to play these files with Soundpad, you need to convert them first to one of the supported formats like mp3 or m4a. You need additional converter software to accomplish this task, or you can use an online audio converter service.
