Fresh Air uses a proprietary psychoacoustic algorithm. It listens to the harmonic content of your track and selectively enhances the "air" frequencies (generally 8kHz to 20kHz+) without making the source sound thin or brittle. It effectively adds "breath" to a recording.
Digital EQs, by contrast, are linear. If you boost 15kHz by 6dB on a digital EQ, you get exactly 6dB of boost. If the vocal has a harsh spike at 10kHz, you just made it 6dB harsher. Fresh Air behaves like an analog circuit. It applies dynamic saturation.
Try using two instances of Fresh Air. The first instance on an instrument bus (Drums) with Mid-High cranked. The second instance on the Master Bus with the High knob barely tickled. This cumulative effect creates depth. The individual elements have presence, and the overall mix has glue. The Verdict: Is It Worth It? To ask if Slate Digital Fresh Air is worth it is a trick question—it costs nothing. But regarding your time and CPU usage? slate digital fresh air
Fresh Air does not have an internal sidechain. However, if you are using a DAW like Ableton Live or Reaper, you can create a parallel chain. Duplicate your track, apply Fresh Air 100% wet on the duplicate, and then EQ that duplicate. Cut everything below 1kHz on the duplicate. Now, Fresh Air is only adding air to the high end of your source, leaving the low end perfectly dry.
For years, engineers have chased that high-frequency magic using complex multi-band compression, dynamic EQs, and expensive analog hardware. Fresh Air simplifies this process dramatically. But is it just another exciter? Or is it a genuine secret weapon for your mix bus? Fresh Air uses a proprietary psychoacoustic algorithm
Rebuttal: Fresh Air is incredible on jazz and classical. If you have a dark string quartet recording, a touch of Fresh Air brings out the rosin on the bows. It works on anything you want to make "feel" closer to the listener. Pro Tips: Mastering Slate Digital Fresh Air To truly master this plugin, you need to move beyond the default settings.
If you haven't downloaded it yet, stop reading this article and go to the Slate Digital website. Install the All Access Pass installer (you do not need a subscription to keep the free plugin), claim your license, and put on your master bus. Digital EQs, by contrast, are linear
It solves the problem of "digital coldness" instantly. It requires no manual reading. It is impossible to make a mix worse if you use the Mix knob responsibly. For years, engineers spent hours automating EQ shelves to avoid harshness. Fresh Air does that automation in real-time, for free.
