NinetyPhaser is a four-stage analog-style phaser for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. A four-stage all-pass network creates focused notches and rounded movement, while input conditioning, nonlinear stages, and a modeled output path add responsive character. Choose a smoother open response or a deeper mode with stronger feedback. FEATURES - Four-stage all-pass phaser - Two circuit-response modes - Speed range from 0.05 to 12 Hz - Equal-power Mix control - Stereo Spread with offset modulation - Instrument and line input modes - Mono-to-mono, mono-to-stereo, and stereo-to-stereo routing - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The app provides 10 minutes of full-featured active use, shared between the standalone app and AUv3 extension. Demo time advances only while audio is actively processing. A one-time, non-consumable In-App Purchase unlocks unlimited use in both formats. Restore Purchases is available in the standalone app. NinetyPhaser works on electric piano, pads, synthesizers, guitar, bass, and other sources that benefit from subtle motion or a pronounced sweep.
