Dahlia Tape Delay1.7

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.

Version History Features:
- Adds customisable ramp mode with 3 types. Tape is the standard, Classic matches the 2014 release, jump will do a quick fade out to avoid clicks.
- Made ramp mode also have adjustable speed to determine the character when changing delay time.

Fixes:
- The Dahlia host app no longer crashes when a MIDI connection is dropped.
- The Dahlia host app no longer crashes when it opens with no audio output available.
- Small legibility improvements to UI

Improvements:
- Tab switches cross-fade rather than blur, making UI performance slightly better.
- On iOS, the manual opens inside the plugin instead of handing you to the default PDF viewer. 1.7 Sep 26 Dahlia Tape Delay 1.6 has a lot of small but powerful improvements.

Features:
- Add independent sync mode controls for the right stereo channel
- A bunch of new presets to demonstrate the stereo split
- Overhauled UI layout and constraints to show the full view on smaller devices
- Improved the readability of the selection states
- Improved font size and weight across the board
- Reduced App download / storage size by a whopping 70%

Fixes:
- Allow presets saved in older versions to work with the newer app
- Prevent an audio glitch when accessing the popover UI for the first time
- Tighter transitions on the compact dahlia view
- Improvements to Classic UI for smaller breakpoints

I owe a big thanks to Gavinski for the idea to support independent channel modes and for the helpful feedback in improving the UI patterns across the board.

I'm looking forward to sharing the next stage of Horse Parade apps shortly! 1.6 Jul 11 Dahlia Delay Classic is here, and it's included.

1.5 adds a whole second AUv3 to the app at no extra cost. Dahlia Delay Classic is a reincarnation of the original 2015 Dahlia Delay, 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. Your host now shows two plugins. Reach for the Tape model when you want the considered sound, reach for Classic when you want the simpler, dirtier echo.

Also in this release:

- Fixed a crash on iOS 17 and a keyboard bug on iOS 18
- Fixed a UI glitch in the compact layout
- The plugin and app version now show in the About panel 1.5 Jun 5 Dahlia Tape Delay 1.4
