Saelin Audio has released Shine, a free adaptive clarity plugin built for vocals and acoustic guitar.
I love plugins that speed up my workflow, and this one fits that description perfectly. You drop Shine on your recording track, and it adjusts presence and air in real time based on how you’re performing, without any presets or manual tweaking.
The main idea here is to solve one common problem – a quiet passage and a chorus don’t need the same amount of top-end lift, and fingerpicking and strumming don’t either.
Shine uses real-time audio analysis to shift its processing as the performance changes. Quiet sections get pushed forward, loud sections stay controlled. On acoustic guitar, it leans into pick attack and string detail that tends to disappear in home recordings.
This kind of thing is right up my alley. When I was learning to mix, getting the right amount of shine on vocals was one of the things I spent the most time on.
There’s a very thin line between adding just enough air to bring a vocal forward and pushing it into harsh or brittle territory, and you always have to check the result on multiple speakers and headphones to be sure. The vocal sound makes or breaks the mix, so anything that automates that decision and lets you focus on the performance is welcome.
Shine is especially handy if you’re a singer-songwriter or producer who doesn’t want to spend an evening tweaking EQ, saturation, and de-essing to find the sweet spot.
Since it’s adaptive rather than static, Shine responds to the incoming signal rather than to a fixed curve. There’s nothing to automate, and no advanced mixing skills are required to get something mix-ready from it. You can insert it and record. You can also process existing tracks through it if you already have takes down.
To grab it, you enter your email on the product page, and Saelin sends the download link. Shine is available in AU and VST3 formats for macOS 11 or higher (Intel and Apple Silicon).
The free Shine is the entry point to Saelin’s Adaptive Recording Technology. The paid version, Saelin Smooth, expands the concept into a suite of three adaptive mic characters.
Dusk is warm and intimate for soft vocals, Grain is uncolored and natural for acoustic guitar, and Flare is forward and punchy for choruses that need to sit on top of the mix. Each character reacts to your performance in real time with its own balance of proximity, presence, transient shaping, and sparkle.
Smooth is currently $99 in early access (normally $149) and runs as AU and VST3 on macOS.
