ANINE is a free Spectral Resonance Suppression plugin designed to dynamically reduce harsh resonances and problematic frequencies in audio material. It operates in the spectral domain, meaning it analyzes and attenuates narrow-band peaks in real time rather than using fixed EQ bands.
Just like most CRQL products, this plugin utilizes spectral processing. This gives ANINA a minimum of 256 bands of compression. While this introduces some latency (11ms on average), the trade-off for accuracy and speed is well-worth it in our opinion.
Use lower blocksizes for a tighter feel, and higher blocksizes for better frequency resolution. Even when it seems like it’s not processing, you may experience subtle pre-ringing and very slight changes in timbre and transients. The quirks of spectral processing.
What it exactly does (Technically)
ANINE functions as a dynamic spectral processor, similar in concept to tools like:
But unlike those commercial tools, ANINE is free and focused specifically on resonance suppression. Just like most CRQL products, this plugin utilizes spectral processing. This gives ANINA a minimum of 256 bands of compression. While this introduces some latency (11ms on average), the trade-off for accuracy and speed is well-worth it in our opinion.

Why use Spectral Suppression Instead of EQ?
If you’re producing melodic techno, trance, or ambient (which you’ve worked with before), this type of tool is extremely useful for:
- Smoothing supersaws
- Cleaning atmospheric pads
- Softening bright leads
- Controlling buildup harshness
This plugin is equipped with sidechain capabilities. Make space in a chord progression for a vocal performance, but only when it needs it.
Features
- Opens the overlay window for more controls
- Controls the blocksize of the plugin (band-size x2)
- Completely freeze the filter-spectrum
- Listen directly to what Anina is removing from your signal
- Master amount of reduction
- Adds attack to the spectral curve
- Adds decay to the spectral curve
- Sidechain-input toggle
- Low filter-signal cutoff (200hz – 20khz)
- High filter-signal cutoff (30hz – 20khz)
- Apply a gate to the filter-spectrum
- Visualise both input and filter spectrums
- In/Out gain controls and visualisers
- Built-in TILT EQ, applied to the compression signal
Conclusion
ANINE Free Spectral Resonance Suppression is a solid corrective utility plugin.
It is not a creative enhancer, but as a resonance taming tool it performs reliably and transparently. For producers needing quick, automatic harshness control without complex setup, it delivers high value – especially at zero cost.
If you’d like, I can also compare it to tools like Soothe-style processors or explain ideal settings for your specific genre.
