Product description

Usually the final mix of a music production does not translate well with all audio devices (e.g. HiFi, car audio, smartphone) at the beginning. To achieve a well balanced audio spectrum in an effective manner is not easy to master!

This is where Euphonia starts:
Euphonia is an optimal audio spectrum balancing plugin which equalizes automatically any audio input based on a few standard average spectrum curves.
These few standard curves have the advantage that they work very well with the majority of audio devices.
Using Euphonia right after the final mix of your music production could eliminate missing low/high end, mixing mistakes, general spectrum balancing problems or even compensate poor listening environment.

Euphonia compares the spectral fingerprint against build-in curves (Pop/Rock/Dance/Jazz/EDM) and calculates filter settings so that the spectrum of the audio follows the selected average spectrum curves.

Euphonia is also able to create custom reference curves to be used for spectrum balancing. Just load any audio file into the DAW, capture the audio fingerprint and save as custom reference curve.

The spectral adjustment is done in a very gentle way, it does not harm any tonal information but impacts the overall spectrum balance. It also tries to keep the overall loudness.

The picture below shows how Euphonia works (screen shot of a spectrum analyzer). It shows the spectrum curves of original (blue) and processed (red) audio file, the difference curve (green) and the areas where Euphonia automatically adjusted the spectrum (yellow):

The effect of Euphonia can be easily verified with any audio spectrum analyzer (e.g. Toscanalyzer) which could compare spectrums of 2 audio files.

It is flexible

Choose from 4 different styles or use your own custom reference curve, for the perfect master!

It is simple

Capture, stop and process, that's all for the perfect master!

When to use

Euphonia is used during the music production process. Spectral adjustments are usually done right after the final mix, but before usage of any sounding equalizer, master compressors or limiters.

Euphonia is also very effective in restoration/remastering environment. It could refresh airless recordings quite easily.

Euphonia could also point out mistakes in the mix or even in the listening environment.

Please check this tutorial how to use Euphonia.

Customer Reviews

Tommy Zai

Euphonia is a handy plugin that is a must for anyone (eMusicians, producers, film and game scorers, sound designer, DJs, etc.), who are serious about making music that stand tall when compared to other tracks in its genre. It helps breathe life into music, not suck the life out of it! Tommy Zai gives Euphonia two keenly balanced thumbs up. Thank you TB Pro Audio for creating such an essential plugin.
