However, I don't listen to headphones a lot, I'm a speaker guy. Therefore I have limited experience with headphone amps (and heaphones) so take my impression of its sound with a grain of salt. bogi 1 ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

I'd like to be able to pick my frequency range , volume of that, and of course the phase. and he negative value pre to prevent clipping. Not sure what exactly you are asking but easiest way to apply EQ in HQP ist to create a TXT-File and load it into the matrix pipeline (one TXT for each channel, so twice the same TXT-File for channel 1 and channel 2 for stereo). Syntax is the same (naming for some filters not exactly the same but similar) as in APO EQ. Syntax for a filter set looks like this (numerical value = XX): Filter: ON [FILTER-TYPE] Fc XX Hz Gain +X.XX dB Q X.XX Short names for Filter-Types: PK = Peak LS = LowShelf HS = HighShelf HP = HighPass (= LowCut) LP = LowPass (= HighCut) (and more - they are in HQPs manual) Q or S for filter bandwidth Fc for frequency Gain (+/-) for gain in dB Preamp for preamp (+/- XX dB) Attached a screenshot of a random setting containing Preamp, peak and shelf filters. Phase can not be adjusted. The EQ is minimum phase by design. You can also create a filter set in REW and export it as TXT. ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

But you can accustom to a smaller collection of your favorite filters and you can try to remember for which kind of music/sound you liked which one and why. Well, the HQP manual lists music-genres per filter. All the filters that are qualified for "any" music style are really good as "set it and forget it" filters. Great choice on behalf of Miska, for sure! I for one use poly-sinc-gauss almost always (would love to use poly-sinc-gauss-halfband always, but there are too many albums in my collection that need an apodizing filter). I used to switch to poly-sinc-short-mp to slightly smooth out the top end with certain rock music. But since I love to switch things on the fly meanwhile I prefer to stay with poly-sinc-gauss and apply an EQ setting to get a similar effect. Rarely do I switch to poly-sinc-xtr-short lp (on headphones) or poly-sinc-xtr-short-mp. Very ralrely to a longer filter for classical music (sounds too good also with ps-gauss to bother). ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

Many thanks, Miska - much appreciated!! 2 hours ago, Miska said: "Only suitable for highest technical quality source materials". Which means it is not suitable for 95+% of RedBook content. This morning I‘ve recorded the output of my Desktop-DAC with gauss-hb and gauss-hb-s. With a Tascam DR100 🙄 - but, hey, that‘s all I have to digitally record analog line level input. Anyway. I have a 44.1kHz/16 album that doesn‘t trigger the Apodizing Counter in HQP due to a steep high quality LPF but the actual musical content goes up to 22K (with quite some energy). While I would find the images produced by the hb filter at least acceptable (images peak below -90dB) the hb-s filter shows pretty strong images. It‘s fine, though, with recordings that roll off gently and don‘t contain high levels above 20kHz. So I would say the Apodizing Counter is a great guide if you use for instance ps-gauss-short but the use of gauss-hb-s sure requires further attention. With an appropriate recording it‘s really great! ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

But instead overall textual descriptions and suggestions. Some number, or a graph don't really give a good answer. Answer is more complex, it would be long series of mathematical formulas. While I also find graphs enlightening quite often I am finding your way to describe the filters extremely helpful! For example: if you look at the graphs of ps-gauss (white) and ps-xtr-short (blue) one could think ps-xtr-short reproduces more "space". But due to the "design" of the filters infact ps-xtr-short clearly sounds more intimate - you really focus on the tones of each instrument. It sounds incredibly detailed. So "Timbre" is an accurate way to describe the characteristic of this filter (IMO). I love this filter when listening to headphones (with Rock/Pop/Electronic/Jazz/Accoustic) Then there's of course also personal perception. Me for instance I am having a hard time to agree on the different descriptions for ps-gauss and ps-gauss-long. Looking at the frequency response plots I wouldn't expect that I could hear a difference between the two at all. The description in the manual states, "timbre" and "transients" for both and for the long version also "space". Strangley I perceive it the other way around: I am finding the ps-gauss filter more "open" and "airy" than ps-gauss-long. Only plausible explanation I can think of is I am sensitive to the longer ringing in ps-gauss-long (which in itself has no "long" ringing of course, but somewhat longer than ps-gauss). Maybe that doesn't make sense at all, but that's what I am hearing. *edit: added gauss vs gauss-long below for reference bogi and Miska 2 ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

But regarding tilts yours (green) is a little bit wavy. Not that it matters much, but for a really straight tilt (pink) you need 5 evenly cascaded 1st order shelf filters; you use only 3. Meanwhile I always use these values for LowShelfs: 50Hz (x4=) 200Hz (x4=) 800Hz (x4 =) 3200Hz (x4=) 12800Hz. For a -2db downward tilt your 3x -0.66dB would be 5x -0.4dB with my settings. So like this (I use Text files): Filter: ON HS Fc 50 Hz Gain -0.40 dB S 0.5 Filter: ON HS Fc 200 Hz Gain -0.40 dB S 0.5 Filter: ON HS Fc 800 Hz Gain -0.40 dB S 0.5 Filter: ON HS Fc 3200 Hz Gain -0.40 dB S 0.5 Filter: ON HS Fc 12800 Hz Gain -0.40 dB S 0.5* * "S 0.5" = "q=0.50", so the same EMINENT 1 ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

copy_of_a Posted October 6, 2023 Share Posted October 6, 2023 8 hours ago, bogi said: I am still using more years old outcome of that script. I will re-run it according to your recommendation. Thanks! your welcome! While we're at it. "Tilt" usually means the lower spectrum gets boosted and the upper spectrum gets attenuated (or vice versa). Since (here) we only use HighShelfs with negative gain everything gets attenuated. So it makes sense to level match the tilts near the center frequency by adjusting the preamp gain. Center frequncy is actually 632Hz but for convenience I myself use 500Hz. This way switching filters on the fly also doesn't trick our perception too much. When you only use attenuated HighShelfs things seem to sound dull at first when you switch to a stronger tilt. In truth everything gets somewhat quiter and that influences perception a lot. But when the tilts are level matched somewhere at the center of the spectrum you don't perceive a volume change but in fact what a tilt is supposed to do: linearly boosting the lower spectrum and attenuating the upper (or vice versa). (instead of gain adjustment of the whole curve you could also make the 2 lower frequencies LowShelfs with corresponding positive gain instead of HighShelfs with negative gain. In this case - based on my curve points above - the curve tilts somewhere around 400Hz, which is also ok for a coherent listening experience when switching filters.)

copy_of_a Posted October 7, 2023 Share Posted October 7, 2023 Your approach is perfectly fine! But there are many ways to skin a cat. The tilts come into play when you think about "tone controls" (bass/treble). It's just a certain way to EQ your music (in a parametric EQ, BTW) in a non-intrusive way. 7 hours ago, Kalpesh said: thank you. I'm not sure I understand the rational though. (...) Say I'm annoyed by a bit too much treble (...) I then will lower my treble response but certainly not lift my bass response simultaneously. Music is always about balance. When you lower the treble and apply the same gain values inverted for overall gain - then you have boosted bass (+ mids, depending on the cutoff frequency and slope of your "treble" filter). Simplyfied speaking: when you lower the treble by a certain level (let's say -2dB) a corresponding tilt would lower the upper spectrum by the half of that level (-1dB) and boost the lower spectrum by a half that level (+1dB). The relation is the same. But, of course, depending on the cutoff frequency and the slope of your treble filter the outcome may be pretty different. if you want to adjust for instance "shoutiness" or "harshness" of a recording a tilt will not do it because it's not meant for corrective EQ. As said above: Linear Tilts preserve the spectral balance of the recording; they are the most "transparent" way to make music "brighter" or "darker". If you don't like the sound or are more accustomed to other ways to EQ the music to your liking that's perfectly fine. There is nor wrong or right. BTW: the room target curves - beside the optional bass boost - are more or less tilts [either linear (-1db/octave overall), almost linear (B&K), flat to 1kHz or 2kHz and after that linear -1db/octave towards 20kHz). bogi 1 ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment
copy_of_a Posted October 7, 2023 Share Posted October 7, 2023 2 hours ago, Kalpesh said: I'd truly like to understand (...) why it's supposedly most transparent. Actually it's already in my post above: a linear tilt preserves the spectral balance. EQing always introduces some kind of coloration (how much of course depends on the shape/slope/steepness/gain of the filter); a linear tilt doesn't do that (at least to the smallest possible amount). Downside is it's not felxible 😀 - it's really just: "make my music brighter / less bright" without altering it's character! When I do listen to music I don't want to think about which house curve the mastering engineer was using or think about anything at all. When I feel a certain album sounds too bright I simply apply a moderate downward tilt on the fly (if it's still too bright I select a slightly steeper tilt). I don't even have to think about the cutoff frequency or whether I use a shelf or a bell filter to make it less bright. Really like a bass/treble tone control bulit into a good old HiFi amplifier (that often had broad Low- and HighShelfs centered somewhere around 1kHz). Now, I also use more specific EQ settings. But basically I am happy only with tilts and P-Loudness settings. ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

Maybe I'll buy it again in 44.1kHz/16bit because it's a great Album! edit: just did that. If someone wants a 44.1k version uspampled to 96k and downsampled to 48k - I have one for free 🤪 StreamFidelity and The Computer Audiophile 2 ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

The slightly annoying part is the need for external PSU and the question how well that is isolated from the output. Not huge fan of having one extra variable in the critical path... Reading the specs of the HS02 the external PSU is only needed when the connected USB device (DAC) requires 5V - the HS02 itself is powered through USB from the host computer. With Intonas 7055 series it's actually similar: there's an optional AUX power connection to feed the connected USB device if its current requirements exceeds 500mA. Up to 500mA no external power supply is required. Plus: the Intonas outgoing 5V voltage is linear. Intona devices are made for industrial and medical usage and such - back then when I bought my first Intona I appreciated the fact Intona has nothing to do with audio 😁 ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment
copy_of_a Posted November 16, 2023 Share Posted November 16, 2023 @Miska what‘s the purpose (a possible use case) of converting parametric EQ to convolution EQ? ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment

What kind of linear filtering did you implement? Forward-Backward? What’s the delay (length)? ____________________________________________________ Mac Mini, HQPlayer | iFi Zenstream (NAA) | Intona 7055-B | Singxer SDA-6 pro | Vincent SV237 | Buchardt S400 | SPL Phonitor One | Beyer DT1990pro | Avantone Pro Planar II Desktop: Audirvana Origin | Intona 7054 | SMSL M500MKII | Pro-Ject Stereo Box S | Aperion Novus B5 Bookshelf | Lehmann Rhinelander | Beyer DT700proX Link to comment
