Infrasonic
TL;DW: Infrasonic is a very clean, plain, high quality subsonic filter, for using inside digital mixes.
If you saw my recent post about Ultrasonic… this is the same, but at the opposite frequency extreme! It will nuke DC offsets and reshape thunderous rumblings into specifically ‘audible’ subsonic rumblings. That doesn’t mean it will always make the amplitude of subsonic bass go down: there may be times when it alters the waveform so it peaks higher. But it’s the same thing as Ultrasonic: tenth-order Butterworth highpass filter, executed as cleanly as possible (NOT with an internal Console system expanding the tone) using very high resolution math.
Normal audio recordists and people working with analog sources will probably find this does nothing for them. But if you get frisky with DAWs and do weird things in the digital mix, you may just end up producing low frequencies that aren’t properly sonic anymore. Normally, you’ll be using various highpasses to tune your deep bass for the purposes of your mix, and this isn’t for that: it’s a more abstract concept of a filter.
If you’d like to neatly excise everything below 20hz and retain EVERYTHING remotely considered an audio frequency, especially if you’ve got DC offsets coming out of your other digital processing (I’ve tried to fix a lot of my plugins that do this, but there are other plugins out there which can produce it), then this might be handy. It’s also one of the Airwindows featureless add-and-forget plugins, and I’ve always liked making those: speeds your workflow. No window to open, just put it in the relevant place and you’re good to go.
All this is supported by Patreon. I’m busily working on some of my grander Patreon-supported schemes, and it’s going pretty well. As always, if you’re in trouble please use my stuff and don’t pay until later when things are better. If you’re doing fine, I appreciate the support, and I hope the things I’m learning and doing are both exciting and useful :)
Hey Chris, signed up to your Patron, I really like what your doing, your passion and innovation are refreshing! Enjoying your plugins and tutorials!
Btw, a little idea – love to know your thoughts on knocking up a small Equal Loudness curve EQ plugin to enable accurate listening at lower volumes? Could be a bit of an earsaver for some of us :-)
Noticed Aurotone impulse responses too, such a cool idea to have ‘second pair’ of monitors, without really having them… anyways, thats a total other thing! Cheers and looking forward to catching up on more of my airwindows homework soon lol, learning a lot!
Best DC offset remover in the universe!
Hey… none of the download links seem to be working on Chrome. I haven’t done much troubleshooting, but it is working normally on Safari, over here – and I reckon nothing has changed, in terms of Chrome extensions and whatnot, since I was last here and downloaded Isolator around the time it was released, so… just letting you know.
I’m on Chromium and just downloaded it. Maybe this was during a moment when I edited PHP versions and took the site down for a few minutes by accident? :)
was doing this for me too. using “Open Link in New Tab” worked though.
