Mono wav file will be converted, but fails to upload to MD

A mono wav file will be converted, but fails to be uploaded to MD. The upload progress bar says 'NaN%' and waits forever.

Thank you for letting me know - it's encoded using an unsupported codec ('adpcm_ms'). Were you uploading it as SP? I will see if it's possible to bundle in that decoder.

Yes, the upload was in SP mode.
I haven't thought about if the resulting track would become mono SP or stereo SP with both L+R being the same. I just found this by accident while testing wipe/upload and needed a short file without realizing it was a mono wav...

The fact that it's a mono wav is not the problem. It is not standard PCM - that's why it fails to upload.
