Following up on my Staple Plug-Ins post, I wanted to share a few tools I use that do a great job at specific, unique tasks. Leave a comment below and let me know what your "special occasion" plug-ins are!
UAD Ocean Way Studios. I've had Ocean Way for a couple years and I'm still so pleasantly surprised every time I use it. It seems to completely transport recordings into different, and much nicer sounding environments. It's been a lifesaver when the tone of an acoustic instrument hasn't landed quite right, and it's also great in place of a reverb when you're looking to create spaces that are small but not totally dead.
Sonic Charge Bitspeek. There are a lot of vocoders out there, but this one has a beautiful tone and unmistakable crunchy edge, like if Stevie Wonder was a Speak & Spell. You can hear it on the bridge of my song "Desolation" (and you can compare it with the other very normal vocoder that also punctuates that song).
Soundness SoundSoap. This has been an essential tool for when I find myself recording in less than ideal locations, like a dentist's office. It almost magically removes any consistent background noise. Air conditioning, refrigerator hum, amp buzz - smell ya later!
