Hello some n00b questions from me .
Preamble , been using squeezelite for years on my PC as a desktop player
.
Now i got two Raspi3 one with A IQaudioDAC+ and one with a
HifiBerryDigi+or pro or whatever :D (then one with transformer isolated
spdiff )
Now i realise first hand the greatness of the combined architechture of
for example PiCore SqueezeLite and LMS (I also trying Max2Play and plan
to try DietPi too ) yess .
NOW MY EXPERIMENTS ,
*Resamplig for my MeridianG68J preprocessor* , it's a bit old and
certainly does not have the latest and greatest internal up-sampler.
And certainly not any protection against intersample overshots .
Plan some attenuation to provide headroom and let SoX do the math to the
Meridians maximum rate of 96kHz . So that it never needs to use it's own
resampler.
Code:
--------------------
-r 96000 -R vMX::3.5:::::
--------------------
Code:
--------------------
-r 96000 -R vLX::3.25:::::
--------------------
Attenuation varies that was just some examples . This works no problem
here but.
*Questions:* what happens when I play a 24/96 track ? Does it just
attenuate or do nothing ?
Desired outcome, it should do nothing when getting a 24/96 track . The E
parameter does not seem to be the rigth tool . Or is squeezelite smart
enough to realize there is nothing to do here ?
Having some benign attenuation done to everything is not a real problem
, but I prefer a solution where 24/96 are just send to the Meridian as
they are .
*The IQaudio DAC for my headphone amp* and an extra set of active
speakers . the TI chip is documented for not having intersample
headroom
Code:
--------------------
-R vMX::3.5::::: -V Digital
--------------------
Code:
--------------------
-R vM::3.5::::: -V Digital
--------------------
Code:
--------------------
-R vLX::3.5::::: -V Digital
--------------------
Code:
--------------------
-R vL::3.5::::: -V Digital
--------------------
......
Etc again examples .
*I explain the volume control *. I also use this player for a pair of
active speakers . When using the headphone amp volume is fixed at 100%
otherwise attenuation would not make much sense .
It's when i use the speakers i use the volume .
-V Digital Here i ponder if should use the X option ? asynchronous
filter or not ? what makes sense for the IQ audio TI DAC or in general ?
is there a "best practice"
Volume control whats best practice here Squeezelite itself or the via
"-V Digital" Which then should use the TI DAC's own volume .
Btw is there a donation button for Squeezlite ?
