Yes, it is possible. Hans himself tried it!

Hi,

I unfortunatly cannot run Stereo Tool on my RP3. The sound breaks all the time (underrun). Tried both Ubuntu Mate & Raspbian, same thing!
I tried both the GUI and the command line and get similar results. I more target to use the command line to process audio input from sox and to pipe it to aplay or to encode it and send to Icecast server.
The CPU load remains arround 30% but the sound breaks all the time so it is not audible.

DELAY: 8192 samples (4096 stereo samples)
2097148K bnd1 bnd2 bnd3 bnd4 bnd5 bnd6 bnd7 bnd8 bnd9 bnd0 input output
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo####
underrun!!! (at least 883,887 ms long)### #### #### ###v ###v ######- #------
^CAborted by signal Interrupt...#### #### #### #### #### #### ####### ####^^-


Any idea? Thx

You might need to play with some Jack settings.

I've had it working on a PI3 with jack previously.
My conclusion was that the PI was not powerfull enough to process stereo and rds, also because Stereotool only used 2 of the 4cores, normaly not a problem, but because of the limited processing power. on the PI it was a problem.
I hope with the multicore Stereotool it will be better, but i'm not sure it it is already availlable for the Raspberry PI.

Also I was not verry happy with Jack, i've had it working, but for autostart it's verry difficult or even complete useless.
Jack id's given to a audio pipe could be different id's after a number of reboots, so then the Stereotool and VLC in/outputs are not working anymore and you need to manually reconnect these.
And jack must be started before stereotool starts.

Maybe I will give it a try to test the performance with multicore proccesing when it's available.
