Convert AIF files to SLN

I just upgraded an old system and want to use the high quality SLN or other format that has been quality. Do I have to rerecord the IVR or can I just convert them to SLN?

It seems to me “convert” has an option for that. You may be able to do it from the System Recordings page. If not, you should be able to get it done through the command line.
