    Would like to hear some feedback about Spatializer/RealPhase's window sizing workaround for Logic Pro's AUv3 sizing bug.
    Are you just using the rectangular (safe) mode, and not really bothered by the larger screen estate being taken up?

    Or do you prefer the appropriately sized window, and are willing to put up with the finickiness of the Logic bug (keeping the size readout at 100%, which itself can be a relative metric sometimes needing extra work).

    I wouldn't mind the window being the same size as the app, but honestly it's not a dealbreaker for me. And I always keep the windows (for both plugins) at 100%. Perfect size for my desktop's screen.

    And by the way, Ringotron on desktop sounds absolutely gorgeous. I am so glad you finally brought it over.

    played around with spatializer in logic on my macbook, just happy to be able to use it, the larger screen estate don't bother me that much

    Ok, cheers. Though there is a setting in both plugins for enabling letterbox-free proper windows, that comes with the aforementioned caveats, so not sure if you tried that as well to see how the two compare.

    Ah just saw what you meant I think. Tried the unsafe setting and opened a new instance in logic. If I enlarge, close plugin, open again: it opens larger than before. If you then close and open again: again larger... Opposite when you make the scale smaller...

    ... and as long as you keep the size to 100% these problems will not occur in the macOS version of Logic Pro.

    So the question is, having a proper aspect ratio without the letterboxing is a strong enough requirement so that you'd be willing to use this setting and put up with the brittle UI behaviour (provided that it's not ruled out in the first place by some crazy ppi / scaling setting that would make 100% way too small, etc...)

  • If I met Quantovox at a bar or coffee shop I would bye him a beer or a latte… so $6 to complete my set of QuantoVox apps is basically a better way to appreciate these subtle FX apps. Spatializer and True Pan useful to improve the imaging impact.

    I also would like to reward a developer that weighs in here on a new release to explain the effort required to conjure up a subtle mathematical approach to sound shaping… these types of apps provide cheap benefits that were only possible with expensive hardware in years before say 2010. The power of the IOS chips combined with significant math skills are magical.

    I gave the test drive to applying this app to PianoTeq 9 primarily because I’m using some cheap Bluetooth earbuds right now and I wanted to hear the subtle changes in EQ and imaging… what I like about most quativox apps is that I can just dial in using my ears without having much of a clue what the controls might do.

    When I get the time I will push the output through some Yamaha Studio Monitors.

    Yes for me. Not that big a deal for me.

  • all in secret hope fettkraft will come too ;) i know of no other that does what it does like that on desktop..

  • Oh yeah, another one. I love your apps, @quantovox - sok sikert!

    Hehe... yes, otherwise we'd just be off topic here, wouldn't we...

    Well on the desktop, in the zero-latency camp there is a plugin (10x Fettkraft's price), which has been a secret sauce for many years now for a number of producers. But such plugins have such a mild effect that people often use multiple instances chained together, which in turn can create other problems. Fettkraft is aimed to solve that - you get an extra strong effect without the annoyances (acknowledging of course that one's annoyance could be another's SFX design tool, or a characteristic in some specific niches of music production).

    So in light of the above, reception on iOS to this effect's arrival is "interesting" to borrow a word from a comment above.

    Or let's rephrase "effect" to "effect category", since the category itself was non-existent on iOS prior to Fettkraft (and we're talking pure, elementary effects, not combination ones). And as such, more apps could be coming later to this category if and when we're all ready... :)

    Cheers! Actually had a devious plan of adding a wild stereo feature to this plugin, but it turned out to be a tricky area, given the typical application area that is percussion sounds, with a big emphasis on kicks for most.
    But it may be revisited in the future - probably should use a different word than "adding", more like "redesigning" :)

  • @quantovox I’m curious what the computer cluster was crunching away on for your product… I would guess it was the kind of matrix math that is useful for defining the behavior of an array of filters. I tend to buy apps that provide push button filters so I can just push buttons until I hear a result that I like.

    I also most avoid this app because I’m not looking for ways to beef up “kicks”. I rarely think of a kick and tend to fall back towards traditional acoustic drum kits since that was my original entre into the world of music. I will audition a lot of kits
    That come with a Lumbeats drummer. But I will see what pushing a kit I like through your magical filter array to see if there’s additional goodness to be crafted.

    I hope the software discoveries you learned making this one applies to more use cases. For that stereo goodness I just add your “Spatializer” or for moving imagery your “True Pan” app. All three can turn a rather basic track into something more engaging.

    Yes, an array of filters is indeed involved.

    For additional uses, you can also check out what's described in this comment.

    Leo's (sfm) demo also features a wavetable sound and a smooth bass which are FAR more interesting than the particular kick sample he featured.

    But as far as basses go, again refer to the comment above, and an important note in the user's guide.

    Speaking of that demo, note that there can be significant differences between the 1 - 9 settings; the higher you go, higher frequencies start to "melt" more intensely - sometimes setting "1" is already considered strong.
    Fettkraft is specifically designed to contain this effect (among others), while even the leading desktop disperser plugin can't avoid that certain "raygun" sound that can make it useless for acoustic sounds for example.

  • I did a little light research on some of the concepts that surface in this thread and ended up wondering what Fettkraft might mean. I got this summary:

    What Fettkraft Means to a DSP Developer

    If a developer is working with or implementing Fettkraft, they are likely focused on the following technical goals:

    • Intentional Low-Mid Dispersion: Unlike telecommunications where dispersion is an "enemy" to be corrected, in audio DSP, Fettkraft uses dispersion as a creative effect. It spreads out the component frequencies of a sound (like a drum hit) in time. 
    • Enhancing Perceived Energy: By spreading the frequencies in the low and lower-midrange, the sound can be made to feel "fatter" or more "energetic" without actually increasing the peak volume (loudness). 
    • Zero-Latency Modeling: From a coding perspective, Fettkraft is notable for being a zero-latency algorithm. Many dispersion effects rely on "stacking" multiple all-pass filters, which can introduce phase artifacts or processing delays. Fettkraft is designed as a single, ultra-strong modeling algorithm that avoids these side effects. 
    • Transient Preservation: Developers use it to "stretch" the tonal part of a sound (like the "oomph" of a kick drum) while keeping the initial transient (the "click" or "snap") intact.

    I just used it again and thanks to your explanation and Fettkraft I was sitting infront of my phone in awe for the first timer in quite a while, thinking that it’s crazy what we can do with these little bricks in our hands now.
    Thanks.

  • To honor national meatball day, for 3 days, anyone can take Fettkraft for a whirl.

    This got you at least one sale… mine. I wasn’t sure what the use case was, exactly. Well the use case is that my drums are absolutely knockin’. Wow. What an asset for the low end.

    If this plugin receives more interest, maybe work will resume on its more complex variant for pitched instruments / vocals (someone mentioned Alan Lamb which is also a direction that can be explored).

    Yes please! As it is I'm really enjoying what it does to the Wurly patch on my live rig. Brings the attack and the body together in a really beautiful way without losing any of the detail of either.

  • How about the other apps of this dev?

    Oh, interesting - but makes complete sense. Would you care to leave a review in the app store about that use case? It would help things tremendously.

    Well when Pianoteq was mentioned earlier (while hoping that the intention was to pair it with some of the pluckier instruments and not necessarily the grand piano), there was an idea to mention that maybe the one interesting thing in there would be to add energy to "piano stabs" and similar sounds. And point to the subtitle of the app :)

    But it seems the plugin can do curiously well a bit outside its niche.

    I absolutely love RealPhase. Great on guitar and, most recently, DynaSinth.
