Peter P:
Hi list,
I am wondering how I could make a VU meter automatically receive all
audio that is sent to specific jack output ports by various
applications, also from those that I will start later on a given day.
thank you for all ideas!
Hi,
jack_capture is able to do exactly what you ask for.
jack_capture is mainly made for recording audio,
but to avoid recording anything, just run it in "timemachine"
mode:
$ jack_capture --meterbridge --timemachine --port system:playback_1 --port
system:playback_2
(make sure "meterbridge" is installed)
