• Inspired by famous phaser units from guitarist and keyboardist world • Unique sonic character combined with a large amount of control • Adjustable LFO; diverse waveforms and synchronizable to host tempo • Versatile: External modulation (parameters), Step mode, and more • Unique Butterfly Meter: Shows LFO modulation and output level • Suitable for all musical genres and instruments • Stereo, adjustable phase modulation distance between both channels • Includes various presets for inspiration • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Phazer will satisfy most fans of phasing effects, seducing them with its rich sonic palette and elegant interface. To achieve the classic phase effect, the original signal is blended with a slightly out-of-phase copy of itself. Altering the timing difference between the two signals produces the swooshing sound characteristic of phasing. Most phaser units available on the market are built around this circuit topology, each with its own specificities and limitations. Guitar pedals provide a great sonic signature out of the box and are a great source of inspiration, but we often overlook the impressive built-in effects sections of some hardware synthesizers. FAC Phazer combines the best of both worlds into a single plugin, offering access to all parameters involved in crafting the phasing effect. The design and development were inspired by both pedals and built-in phaser effects found in hardware synthesizers. This led to the creation of four unique characters: Classic, Midori, Step, and Tirus. All parameters can be applied to each of these characters, allowing you to create new, exciting, and outstanding sounds. The presets Slow, Moderate, and Jumpy Phase Pedal or also Fleur d’Oranger bring the classic pedals sound signature within your reach. If you're seeking more modern characteristics, the Step Sound I preset offers a splendid stepping mode, while the Midori Phase Shift II preset emphasizes the feedback in a unique way. On the other hand, the Tirus Anthem preset is an excellent starting point for exploring phasing effects produced with built-in synthesizer effects. An important aspect that strongly contributes to the variety of the sonic palette provided by the plugin is the modulation options. The LFO can run in free mode, be synchronized to the host tempo, or be defined by external automation parameters. The documentation is available at fredantoncorvest.com/FAC_Phazer.html

ReceptionRating · Positive reviews · Number of ratings

FAC Phazer holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: FAC Phazer has 30 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 83% of FAC Phazer's written reviews are positive against 100% of InDecks's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FAC Phazer ships an update every 4 months, InDecks weekly. Both last shipped on October 24, 2026.
