Re: [SlimDevices: Audiophiles] Triode's USB 24/192 plug in - sound quality impressions

2012-06-02 Thread cfraser

^ I checked SBGK's 999.../4 buffer size, as he originally posted it, and
the "Large" buffer size option. With EDO 0.6. The debug output results
for both are identical to each other and to what you showed in post
#54.

I am still running with 0.6 and SBGK's very large buffer size spec.
Haven't changed it in more than a week, almost afraid to. I haven't
tried comparing results with different buffer sizes for either EDO 0.6
or 0.7.

Thanks. Will check it out and report back.

No consequences other than that - I am interested though if other
settings with the same period time but smaller total buffer give any
difference in your mind?

Thank you for this explanation. When I get a chance I'll try the same
settings with EDO 0.7. I see no reason to doubt the active values will
be the same as the ones for 0.6. But I'll check nonetheless.

When you state that my current settings force the period size to be 256
frames at 44.1 sample rate, are you suggesting any consequences other
than limiting the effective buffer time to 92864?

Guido F.

Thank you for the reply Phil.
This is the first part of the my "custom-convert.conf":

The screen of configuration "tipe of fliles":

As I hope you see, the file type "apple lossless" is not clickable to
select the option "inguz dsp".
Thanks again for your help.

I know that you may find this incredibly hard to believe but there
people who don't have and don't want an iPad, iPhone or any kind of
smart phone. Plus Airplay isn't all that great, especially when one
takes into account all the file formats it does not support, which is
just about all the non-Apple ones.

This is interesting.  I thought you were using a period count of 4.  In
this case the period count is so large it hits another limit (total
buffer size) in the driver.  This means that the period size/period time
are constrained and in this case are far lower than even the default
values.  So with these settings you are getting a period_time of 5.8ms
which is less than the default 10ms. However I also maintain you will
see this with both EDO 0.6 and 0.7.

For this setting you will get exactly the same active values with buffer
time of 10 and a period count of 16.  The limiting factor is the max
buffer size which is 32k bytes or 4096k frames.  So by setting the
period count to 16 you are forcing the max period size to be 256 frames
which is 5804us at 44.1k sample rate.  In this case you will get the
same values for any size of buffer time of 92864 (16*5804) and above.
