Balancer
Key Features
- AI-driven spectral analysis powered by sonible's smart:engine detects and corrects tonal imbalances automatically within seconds
- Source-specific profiles for vocals, guitar, drums, and other instruments optimize the AI algorithm for each input type
- Three Flavour modes (Neutral, Warm, Bright) let you shape the overall tonal character beyond simple correction
- Intensity slider provides smooth control over how aggressively the spectral balancing is applied
- Content-aware processing built on psychoacoustic principles interprets audio context rather than applying generic EQ curves
- Supports sample rates from 44.1 kHz up to 192 kHz for professional workflows
- Streamlined interface with minimal controls designed for fast results without complex parameter tweaking
Description
Balancer is an AI-powered spectral EQ plugin developed by sonible in collaboration with Focusrite. Built on sonible's smart:engine, the same technology behind smart:comp and smart:EQ, it listens to your audio for a few seconds and automatically corrects spectral imbalances using adaptive filtering.
The plugin includes source-specific profiles for vocals, guitar, drums, and other instruments, letting the AI tailor its analysis to match the input signal. An intensity slider controls how much correction is applied, while the Flavour control switches the tonal character between Neutral, Warm, and Bright settings.
Balancer combines psychoacoustic principles with real mixing experience baked into its profile calibrations. The content-aware system detects deficiencies in spectral balance and adjusts a bank of filters accordingly, delivering results that users describe as surprisingly musical and effective.
Producers have found it particularly useful on vocal tracks, acoustic guitars, and as a quick spectral correction tool before more detailed mixing work. Several users compare its approach to OTT-style processing but note that the results are cleaner because Balancer uses match EQ rather than multiband compression.
The plugin supports sample rates from 44.1 kHz to 192 kHz and uses machine-based authorization through sonible's account system. Note that sonible has officially discontinued Balancer, though existing license holders can still use their installed copies.

Frequently Asked Questions
Is Balancer still available to download?
Sonible has officially discontinued Balancer, and the product page now states it is no longer available. However, if you already claimed a license during the original giveaway period, you can still use your installed copy with your existing authorization.
How does Balancer differ from a traditional EQ plugin?
Unlike a manual parametric EQ where you set each band yourself, Balancer uses AI to listen to your audio and automatically generate corrective filter curves based on the source material. It detects spectral deficiencies and applies adaptive filtering, which makes it more like an intelligent match EQ than a conventional equalizer.
Can Balancer be used on a full mix or only individual tracks?
Balancer works on both individual tracks and full mixes. While it was primarily designed for correcting individual instrument and vocal tracks using its source-specific profiles, users have also reported good results using it on bus channels and even master chains as a subtle tonal balancing tool.
What is the relationship between Balancer and sonible's FAST plugins?
Balancer was the original collaboration between Focusrite and sonible, released in 2020. Its popularity led to the development of the FAST plugin series (FAST Equaliser, FAST Compressor, FAST Reveal), which expanded on the same accessible AI-powered approach. The FAST plugins have since been discontinued as well, with sonible directing users to their learn:bundle as the successor.
