AudioDeluxe has announced a promotion on Solid State Logic’s native all-pass filter plugin which offers manual control and high-quality response to apply advanced phase correction.
X-Phase enables you to apply a phase shift (phase offset) at a specified frequency within a signal.
Unlike other filter types where the gain of selected frequencies is altered, with an All-pass Filter the gain remains unchanged throughout the signal. This is useful for fixing phase problems with microphones when recording: e.g. overheads causing phase problems when mixed with close mic’s.
X-Phase can also be used to create a comb filter by applying a filtered signal to an unfiltered version of the same signal.
SSL X-Phase features
- Advanced phase correction software.
- Eliminates tedious manual phase alignment.
- Control the phase of specific frequency bands.
- Comprehensive delay control with millisecond, samples, meters, and feet settings.
- Adjust left and right channels independently or together.
The plugin is on sale at AudioDeluxe, Plugin Boutique, and from the SSL store for only $10 USD until August 3rd, 2026 (regular $99 USD). It comes in VST/VST3, AU and AAX formats for Windows and Mac.
