Euphonia3 is an automatic spectrum balancing plugin from TBProAudio that equalizes audio toward average spectrum curves for Pop, Dance, Jazz and EDM.

Best for: Mix Bus, Mastering. Genres: Pop, Electronic & EDM, Jazz, Acoustic & Classical.

Keywords: full mix, bus processing, mastering, minimum-phase, mix bus, static, thin.

What it does

Euphonia3 is an automatic equalizer that pulls any audio toward a standard average spectrum curve. TBProAudio aims it at the moves usually made "right after the final mix": missing low or high end, mix mistakes and general balance problems.

Target curves: four built-in styles, Pop, Dance, Jazz and EDM.
Custom curves: capture a fingerprint from your own reference audio, load WAV or AIFF files directly, and save or load fingerprints.
Capture and process: the plugin first captures the input's spectrum, then applies the correction toward the chosen curve.
Filter design: IIR minimum phase with zero delay, or linear (zero) phase filtering.
Strength and blend: a filter strength control and a free mix between original and processed signal.
Output: adjustable output gain and peak gain matching, so you can compare without a level jump.
Workflow: 64-bit internal processing and free GUI scaling.

The current version is 3.0.22 (May 2026), with free updates for existing customers. The demo briefly mutes audio every 90 seconds.

When to use it

Euphonia3 is the better pick when you want a fast, automatic check of a mix's overall tonal balance against a target. Unlike Pro-Q 4 or TDR Nova, you don't set bands; it works out the whole correction from the captured spectrum and a curve. Compared with bloom, which adapts tone subtly and continuously, Euphonia3 makes a stronger, curve-based correction that you then scale with the strength and mix controls. Its custom curves make it a simple reference-matching EQ, though it has no manual bands for fixing a single problem frequency.

Best for: final tonal balance on mixes and masters, matching a mix to a reference spectrum, and a quick check in a poor listening room.
Genres: pop, dance, EDM and jazz match its built-in curves; custom curves cover other styles.
Look elsewhere if: you want hands-on control of each band (Pro-Q 4 or TDR Nova) or subtle adaptive tone shaping (bloom).
Tip: a KVR reviewer notes that offline capture is faster than capturing in real time.

What producers say

User feedback is thin but positive; the only KVR review dates from version 2.

KVR users rate it 5 out of 5 from 1 review (version 2.0.3, 2019), which praised the "gorgeous" interface, the more accurate spectrum matching and reasonable CPU use.
Uses: the same reviewer found it helpful for dance music and also used it for restoration, sound design and single tracks.
