Hi,
So I decided to try using a USB soundcard with my RPi 3 to
get lower latency, and higher quality output but it seems that
it is in fact higher latency. When using the card I get the
message:
fluidsynth: warning: Requested a period size of 64, got 940
instead
With the audio jack on the RPi I get:
fluidsynth:
warning: Requested a period size of 64, got 256 instead
I
notice that the sound card is slow because I have special
effects firing off of the RPi's GPIO ports and I can see
that the effects fire a split second before the actual
sound. This is disappointing :/. With the audio jack built
in to the RPi it is better but I would like to reduce the
latency as much as possible.
Here
is the USB sound card I bought:
Any
advice?
Thanks,
-Chris
