Dahlia Tape Delay is an AUv3 effect built as a love letter to a bygone era. WOW & FLUTTER Noisy oscillators drive pitch modulation to give the same organic variation from tape aging. TAPE HEAD EQ A filter models the frequency response of the playback head of an analog tape delay, adding warmth and high-end roll-off in the feedback path. FEEDBACK Tape compression at the end of the signal path lets you push feedback to its limits without fear of runaway. STEREO / SPLIT Independent left/right delay times, ping-pong mode, stereo width, and spread controls using a mid/side splitter. FEATURES • Four delay time modes with host sync. • Independent left/right delay times. • Ping-pong stereo with adjustable width. • Tape wow + flutter modulation. • Feedback path with tape EQ and head response filtering. • Drift-compensating delay lines for stable long delays. • 12 factory presets. • Support for custom presets DAHLIA DELAY CLASSIC: The app includes a whole second AUv3 at no extra cost. Dahlia Delay Classic is a reincarnation of the original 2015 Dahlia Delay - it's a stereo delay with a resonant filter in the feedback path and a subtle pitch modulating warble. This new rendition has a more performant audio engine, host sync capabilities, improved presets and a more modern UI. Faithful to the original character, but with a new look and feel. COMPATIBILITY Runs standalone and as an AUv3 audio unit. Compatible with GarageBand, AUM, Cubasis, and any host that supports AUv3 effects on iOS 17 or later. — Timothy J. Barraclough / Horse Parade
