Stereo Tool

I believe it has been this way for years.

BETA018 is posted. Not much has changed in Stereo Tool (except under the hood, in preparation for the new GUI, but that shouldn't be noticeable). The biggest change is that there is a new MicroMPX version (V4), which uses far less CPU (28% of one core on my Pi 4, down from 52% for V3 a few versions ago - even if you keep using V3 it's using less than before now). V4 has an improved encoder which achieves slightly better results at the same bitrate, and allows for using much higher bitrates than before (the maximum was 576, it's now probably around 900-1000, I've put 800 as the maximum in the software for now).

*WARNING* - until this version is officially released we might still make changes to the protocol, which could break compatibility. So, if you roll out this version and enable V4 in the settings, be aware that you might need to update all your encoder and decoders again once we release it.

Hi Hans
Yes the event license works now!. thanks
Do you have a manual how to update the micrompx decoder on a raspberry pi to the new beta version

If you're using our image, log in with ssh (for example with putty) or directly on the Pi itself if you have a monitor and keyboard connected, and then run "update.sh".

Username / password: mpx / micro
Then just type
./update.sh

And follow the steps there.

Thanks i thougt that this was to update for a release and not for also a beta version. And what command can i use for checking the version?

Hi Anton

You could try something like...

grep -i "Starting MicroMPX" .MicroMPX_Selected_ARM32.log/* |more

...which will show you the version info when it starts like - info: Starting MicroMPX 3.1.1 / build 0336a05
Not sure what the built # represents? Hans?

I cannot change presets in the web interface with the standalone version anymore, reverting back to beta 002 for now. Sorry to report the bug.

[update] Just looked at the release notes for beta 018.
"• BETA018: Loading presets from webinterface fails"

I assume this will get fixed soon, and thanks for all your hard work!

O! You're right - this won't work for the beta. For the beta you'll have to download it manually. I don't have access to the script now, but you can check how it's done in the script (it's just a few lines, I think I was using wget to download, if not it might have been curl).

I edit the script.
the only strange thing what is see is the MicroMPX_selected_ARM32.working is not the 10.329 KB as the downloaded version.

echo For a new release, run also update_release.sh

"working" means the last working version, ie. a backup. So it may indeed have a different size.
