    Is there any source material that can help in understanding the principals of the various filters and help understanding their effect on the sound? the short explanation of each filter in the user manual is a brief detail of the filters method but to me it doesn’t explain what I should expect from the filter. For example I understand that a Sinc filter applies a Sinc function and that a poly gauss applies a gauss type poly function but how each one changes the sound is not implied from this. Is it only explained by listening or is there also some verbal justification (pros/cons, effects) that can be described somehow?

    I usually use ext2 or sinc M I am now trying out gauss-long I tried going to gauss xl/xla but I am getting choppy playback. Music has a hiccup every few seconds. Not sure why. Are these much more cpu hungry?

    @Miska can you explain this? When I did my sweeps I actually applied the exact same upsampling and noise shaping as I intended to use, so apparently I messed up and need to do it again, But would like to understand why or what is the logic? My logic was that I want to play the sweep through the entire audio chain in order to capture the entire effect of all components and to that also the effect of HQPlayer - after all one of the claims for upsampling is that it improves the transients and also helps mitigate some of the room modes. I believe the general guideline for creating convolution filters for digital room correction is to first do your best to fix anything you can with speaker placement and physical acoustic treatments If I create the impulse response without the effect of HQPlayer isn't it like not optimizing the speaker placement before measuring the impulse response?

    Would appreciate advice on preferred Linux settings when using Roon+HQPlayer embedded on same computer What would be the preferred settings: 1. Dual core with multi thread enabled/disabled? Or: 2. CPU c-state set to “no sleep” as I understand both can’t be enabled together. would also appreciate understanding if core isolation/dedication is recommended or not. many thanks.

    I’m on 4.25.2

    @Miska I'm getting a HUGE pop from my speakers when crossing the loudness compensation higher bound. Amp goes into protection mute and will resume only if I go beyond or below the "higher bound" setting. Doesn't happen with lower bound. This is concerning... Why is this happening? Here are my settings: Bass frequency=80 Bass steepness / Q =0.4 Bass level = 10 Bass type= lshelf Treble frequency =5000 Treble steepness / Q =0.3 Treble level =5 Treble type hshelf Range lower bound = -40 Range higher bound = -20

    @Miska is there any way to set “startup volume” to behave as “last set volume” instead of a fixed number? I tried leaving the input empty but it is not accepted (Roon cant gain control of HQPlayer if there is no value in this field)

    I don’t see how I can as the IIR eq only has “peak”, it doesn’t have “peakq”. maybe I’m missing something here… by the way - I accidentally set the Q for the treble to 0.0 and got a nasty loud pop from my speakers… maybe you should protect against it.

    Thanks, After playing with loudness for a bit I really like it. I still didn’t understand the difference between selecting “peak” or “peakq” from the filter type drop down. The Q/steepness parameter is in a different field so I guess that is confusing to me. what would the curves look like for the 2 attached settings? (Only difference is the peak vs peakq filter type)

    Thanks, I will try the defaults. At what range of volume does the "Loudness" have an effect? is that set by Lower/Upper bounds? Meaning - loudness boost is at maximum (bass/treble frequency settings) when volume is set to "lower bound" and gradually reduced up to "upper bound" and if volume goes higher then "upper bound" there is no more loudness compensation? Can you also explain what is peak and peakq? MANY thanks

    @Miska Is there any reference/guide for the usage of "loudness" in HQPlayer embedded? I don't see any details in the "help" section of the web interface
  12. @MartinT I am no fortune teller but I see a third clock or a triple output clock in your future :-) After all you don't want the Gustard to feel left out... Any special reason you have your TP link on the P10? I believe there is enough separation and isolation in your chain, but it does look as if after all the the dirtiest component has the shortest path to the amplifier (maybe this even shorts the ER moat??)

    Any comments/thoughts on using Roon’s volume leveling and cross fade before HQPlayer? I really like using these 2 features from Roon and unfortunately they can’t be used in HQPlayer directly based on current implementation between them, Are there any downsides of not sending the bit perfect stream to HQPlayer by using these features? (HQPlayer performing convolution and upsampling to PCM 768) maybe it’s actually a benefit as the stream reaching HQPlayer is now 64bit?
  14. Thanks @Miska In my case the control is needed for Roon, as it is Roon that controls the play/pause next/previous and not HQPlayer, I think I maybe @spockfish can help out here. If HQPlayer is like any other control zone or endpoint in Roon, then from what I am able to understand Flirc remote will work since you can select which Roon control zone it controls. As long as Flirc usb is supported on the Allo USBBRIDGE signature with RopieeXL I should be good to go.
  15. Hi Trying to figure out if I can get IR control for Roon with HQPlayer I am wondering if the Flirc USB remote, https://flirc.tv/more/flirc-usb, can work with HQPlayer NAA and Roon The setup is: Audiolinux computer running Roon Core + HQPlayer Embedded Allo USBridge Signature running RopieeXL with HQPlayer NAA It is not clear to me if connecting the FLIR USB receiver to the Allo will act as a remote for the NAA (in which case it is useless, since the controls on the HQPlayer don't control Roon. Using them from the web interface causes Roon to lose control - which is what is expected, but useless) Or, Does the FLIR work as a stand alone control for a specific Roon endpoint- in which case I will be a able to set it up to control the HQPlayer endpoint which means it performs the same as the Roon remote application on a smartphone? Many thanks
