Hi,
I have followed the video of Hanz who demonstrate ST on a Pi4 with HIFIBERRY DAC+ ADC sound card to produce mpx signal.
I have tested, but i'm not satisfied of the sound quality. I just use the composite clipper, because source is already treated by ST in studio, but the quality of the treble is not good. Is it due to the sound card ?
Someone use this config and have the same problem ?
Regards

I think I found the problem.
I started with old version 9.3x
In this version, only Quality (to limit CPU was available).
In version 9.50 there is Quality and Limit CPU settings. Quality was set under 100% but sound quality was not good.
After changing Quality to 100% and Limit CPU to Low (Pi4), the sound is goot and the PICPU don't grown above 60% :-)
