Stereo Tool

This is not my first post - my account got deleted. I've been using ST since 2010 at least!

I cannot get Backup Player in uMPX to work - is there a particular file format it expects, or file-naming convention or characters it does not like? I'm using C:\File-Name.mp3

- Even with "Play backup file now" ticked it does not play. The file plays fine in Groove music on the same PC.
- It does not say it cannot find the file in the log.
- I've tried setting timeout to minimum and "Act as each dropout last" to maximum 60s.
- The measured loss counts up towards 100% but never quite gets there.

I can't see any info on this feature in the documentation. Any advice appreciated

I changed the file type to wav and then it told me it expects a 192kbps mono file. When I give it that (an mp3) it still gives an error about a header format or something, yet all the files I give it play perfectly in in-built windows players. uMPX seems VERY fussy what sort of audio file it wants. Does anyone know the secret formula?!

Atleast there is some player. ST does not have it at all. I need to keep external player in background looping list with vac on ST. Also it does not work well with asio and input buffer is full after a day, no matter what.

Anyway i generaly dont care about uMPX, but maybe it asks for 192kHz file? not 192kbps.

Like Bojcha said - you need to run mono wav file at 192Khz sample rate. You can pre-record MPX signal processed through ST and record it.

Digging out this topic.
Can I use the ST commandline version to generate an MPX file? Recording it in realtime is a bit tedious.
