Frequency-aware kick & bass management for tight low ends.

AXIS splits your kick and bass in the frequency domain and uses dynamic ducking to keep the two from fighting for the same space. A real-time scope shows exactly where the crossover sits, so you can shape the relationship by eye instead of guessing.
- Spectral crossover between kick and bass with adjustable position, slope and gap
- Dynamic ducking — pull the bass out of the way of the kick by a set depth, smoothed over time
- Live scope & FFT view of both signals across the crossover
- Bass note detection with frequency readout
- Per-channel solo (Kick In/Out, Bass In/Out) for fast A/B checking
- Curve presets plus an Easy mode for quick results
- Input, output and gain-reduction metering
