Given that jack is cross-platform and meterbridge is a X11 application it's not very likely to be bundled with jack itself.

You may also want to have a look at https://lists.linuxaudio.org/archives/linux-audio-dev/2012-June/032475.html - the debian package applied this, but it never reached upstream, it's likely not relevant after your re-work either. A better candidate to be bundled with JACK would be https://github.com/njh/jackmeter (although I tend to prefer jack_capture /dev/null, b/c it does multiple channels). A simple command line meter for troubleshooting would be great. But ballistics are of secondary importance, this is more to check if it's alive. That also means it should go down to -100dB or so. That said, a "signal present" indicator would help in all patchbay applications such as patchage and qjackctl (switchable of course to not waste resources when not needed). -- Jörn Nettingsmeier Tuinbouwstraat 180, 1097 ZB Amsterdam, Nederland Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio), Tonmeister VDT http://stackingdwarves.net ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev

It is simple, clear and runs well in a standalone environment. It also acts as a useful summing point. One's ears are the final arbiter but this is very helpful. I will check out your build as soon as I have some free time (whatever that is!) -- It wasn't me! (Well actually, it probably was) ... the hard part is not dodging what life throws at you, but trying to catch the good bits. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev
