Interesting, I havent tried IIR and I have an R2R
Be sure to report back what you think, IIR does make sense to sound good on a ladder DAC since youāll benefit from the lack of pre ringing and hf roll off.
I feel that. Thatās where Iām at with sinc-m and a schiit multibit dac, which I think benefits from the apodizing and extended high frequencies.
Really wish some other manufacturers would make some pseudo-ladder dacs with these types of ICs. I think thereās serious end-game potential there and would love to see what other implementations people come up with.
I run a OCed 7700k right now, ASMD7EC + DSD256 + ext2 is possible and stable as long as you donāt to to much else on the computer. Not as fast as newer CPUs obviously, but considering its a 7:th gen you realize that Intel has not exactly done any big leaps in performance the last 5 years.
I also like IIR sometimes, very soft and laid-back sounding. But why canāt I use that for over-sampling in DSD output?
Iām curious what something like poly-sinc-ext2 would sound like with even more high frequencies. The difference between sinc-s and -m is quite apparent on a Schiit MB DAC with its filter passing up to 21.344KHz
I think I now have a filter that is pretty much what you are looking for, called poly-sinc-ext3:
How does that compare to ext2?
It is just steeper for those who want steeper ones.
Do you have graph for ext2?
Hereās one with similar scale:
Looking forward to trying this out. Thanks!
EDIT: @jussi_laako would you mind posting a graph of sinc-m to compare?
Thatās getting pretty close to the proverbial brick wall Jussi ! And they said it couldnāt be done ā¦
Nice. Little graphs like this with only FR and IR all set to a common scale would be nice in the manual.
Feature request.
Agreed. It sure would help to be able to visualize them, if possible.
Hi Jussi, when will ext3 be available to use? Thx
edit: nevermind, I see it was released in 4.11.0 today. Look forward to trying
Not if you are a HQPlayer Embedded license holderā¦I hope we get a new version soon!
I can do ext3 with Redbook but not with Qobuz 96kHz streaming using an i7 7700 server when running ASDM7EC at DSD 256. I see in the manual it says that ext3 is 8 times longer than ext2.
@jussi_laako , is it possible to configure HQ Player to use different filters according to the format of the source ? Iād like to use ext3 for Redbook/48kHz and ext2 for higher resolution source material.
Theyāre usually a day or 2 behind. I suspect thereās either double work that needs to be done due to them being different branches of development or because embedded ends up in 3rd party devices, major releases will go to desktop users first to catch any issues before pushing headaches to hardware partners.
Either way, also trying to wait patiently.
I think yes (at least it works OK for PCM to PCM upsampling):
Is that your new favourite filter, replacing the ext2?
