What DarkFire does
The developer describes the harmonics as the integer multiples of a fundamental frequency that are produced when a musical note is played, and these overtones are what give an instrument its character. Because DarkFire processes harmonics separately from the rest of the spectrum, the added colour can be shaped without simply boosting the whole signal.
The plugin is built around a harmonics shaper and an EQ filtering stage, which together let the added overtones be sculpted into a chosen shape. Analog-modelled techniques such as tube saturation and tape emulation are used to introduce the harmonics, which the developer links to added warmth. Parameters can be adjusted to bring out presence, depth and width in the processed material.
Key features
- Separate harmonic processing. DarkFire processes the harmonics of a signal separately from the original audio, then mixes the shaped overtones back in, which keeps the source intact.
- Harmonics shaper and EQ filtering. A shaper and EQ filtering stage sculpt the added harmonics, so their shape can be set rather than applied as a single uniform boost.
- Presence, depth and width. The processing is aimed at adding presence, depth and width, which the developer lists as its main effects on a sound.
Use cases
- Instruments. The developer lists guitars, bass, vocals, pianos, drums, strings and synths as sources to process with the plugin.
- Low-end and high-end. Harmonic enhancement can be applied to kick and bass for low-end punch and warmth, or to vocals for high-end width and sparkle.
