Loss of tone and distortion when above 96Khz.



  • I know some of you saw where there was this issue for some, but those never directly addressed it as a sample rate issue possibly.

    I can't run bias amp 2 at any sample rate higher than 96khz without distortion loss and an overall tinny/muffled tone, that has nothing to do with mic placement as was noticed by some. It directly happens when switching between anything up to 96khz and anything above that (like say 192khz).

    I make sure that both the sample rate and buffer size are "matched" (192khz with 192 buffer size). This isn't a buffer issue as I've tried VERY large buffers and VERY small buffers and it only caused "pop/click" glitches. I know that the USB driver for my Focusrite 2i2 2nd gen is up to date, and so is BA2. Both are set at the same rates and such.

    This is on windows 10 with latest updates on a 64bit machine with 8 gigs of ram (more than enough). USB 2 input on front header, and the USB 3 front header as well... both do it. using included cable. (edit: now on the official back header for usb3)

    I can get 192hz at 24-bit depth and a buffer of 192 as well in Reaper and all the plugins work fine, but load up either standalone or plugin version of BA2 aaaand it happens anyway.

    So something with the sample rate in BA2 is messed up for anything higher than 96khz.

    Anyone able to find a workaround or fix for this atm?

    (And yes, I know there was another thread with this same post, but it was hijacked big time, and just trying to clean up here while allowing that older one to stand, plus someone may now know of a fix?)



  • I've also massively increased the buffer size and no matter how high I put it, I get randomly timed pops and audio outages.

    The rig rundown:

    Bias Version 2.2.3.1303
    DSP Engine 1655
    Build 64bit
    License Tier Elite

    Windows 10
    Focusrite Scarlett 2i2 (2nd gen) run through the back I/O USB 3.0
    8Gigs of Ram at 16000
    250 Gigs of SSD (Mushkin)
    NVidia 780Ti
    Intel Core i5 3570K @ 3.4Ghz/Boost-3.8Ghz

    Anyone able to think of potentially a setting in windows that might affect the tone at 192Khz. Even non-sound related settings, such as USB3 Setting and what not?

    I should also mention that I can use my focusrite to get 192k @ 192 samples with 0 popping and no loss of tone on other professional standalone titles (TH3, etc.)... no problems. This is the only software that does this. I'm wondering if the software is experiencing its own buffer underruns due to a problem in coding or something? As no other program does it, no matter how many effects.



  • Welp, got my ticket replied to, and it seems that they now officially do not support anything above 96khz... guess they couldn't figure out where the glitch/bug is/was or don't give a damn heh. I mean yes it doesn't matter a whole hell of a lot in the grand scheme, but it was one of the reasons I got my Focusrite 2i2 (2nd gen) to record at 192khz, guess I have to stick with 96khz if I want to work with this software. This is a good thing to put into the suggestion thread heh.



  • Ehn. Professional audio has been lower than that for decades. I think these higher rates are gimmick.


  • A2

    I was gonna say, but maybe he is using these higher rates for academic purposes, like aliasing testing or something.

    Isn't it true that 192khz will be LESS accurate to the source signal than 96khz?



  • @pipelineaudio : I don't know that much about it. There might be a multiple-of-the-original-to-match-up thing like with video resolution. If this was analog it wouldn't be a discussion. More tape is always better.
