It's served me well, and I like the sound I get. So much so, that I run an internal buss in my plugins that is 1,099,511,627,776 times more high-resolution than that.
You'll never hear that doing it once… but for every little calculation, which could be thousands or tens of thousands? I think that's a hidden difference between digital audio and analog audio, and I think it matters. They're fast, can be calculated in parallel… but everything you do with them, you erode away louder samples by constantly truncating your internal variables to roughly 25 bits. There are a lot of devs who like using 32-bit floats for audio math. The question is, am I making a choice that is hurting the sound?Ī bit of background. I am pretty sure that I've got Hypersonic outperforming Ultrasonic on every possible platform, even though it has two more filter stages than Ultrasonic. Compare Ultrasonic to Hypersonic… CPU-wise. I'm also working on something else that may give rise to big changes (I know, it's like 2022 is all the promised big changes, but this one might be extra interesting).
It combines enough filter stages to act like a 14th-order Butterworth, and it cuts off just high enough beyond 20K that you should get everything up to insect-repellent audio, unsoftened. I think there's a fair chance this filter will work out for folks whose aesthetic leans toward the superultramegahyperbright, even if that ain't me. It makes sense that the slight softening of super-bright frequencies that original Ultrasonic gives you, wouldn't work for everybody: not everyone wants 'glue' or 'analog' or 'recording console', sometimes you just want the purest digital you can get. Hypersonic is the same as Ultrasonic, except it's running seven stages of filtering instead of five, and it cuts off a little higher: for these reasons, it's the Airwindows ultrasonic filter that ought to not soften the super-highs even for golden ears and sparkling youths I don't think the original Ultrasonic sounds bad and I use its type of filtering in my work a lot, but I also like depth in sound and the presentation of a soundstage that's not too upfront and close.
TL DW: Hypersonic is Ultrasonic, but steeper and higher cutoff.īy request, here are some updates to my ultrasonic filtering asked for… and some that weren't expected
