VarispeedDelay 0.1.2

Full Changelog: v0.1.1...v0.1.2

VarispeedDelay 0.1.1

Click fixes, a wider time range, and the first cross-platform build.

Binaries are produced by GitHub Actions from this tag — macOS is now a universal
binary (arm64 + x86_64), and Windows is included for the first time.

Fixes

• Clicks on every repetition below 1x speed. A generation records input for one period
  but its writing voice keeps recycling past that, leaving a butt join no voice envelope
  covered. The recorded input is now crossfaded into the recycled tail.
• Clicks at exactly 1x after using another speed. Two separate causes: the unity
  bypass assumed each repetition tiles the grid, which stops being true once generations
  are longer than a period; and the fade policy either side of a join could disagree, so a
  fading repetition handed over to a bypassing one and the seam became a cliff.
• Minimum delay time now follows the audio buffer instead of a fixed 10 ms, and the
  time knob reaches down to 0.1 ms so small buffers are actually usable. The readout shows
  the real period when the buffer floor binds.
• Microphone permission is declared, so the standalone can actually open an input.

Changes

• Speed shortcuts are a 3x3 grid: octaves at 1/4, 1/2, 1, 2, 4 plus fourths and fifths.
• Relicensed to AGPLv3 (the project uses JUCE under its AGPL option); the code written
  for this project is additionally offered under MIT — see COPYRIGHT.md.
• Engine and processor are covered by tests asserting the audio path never allocates.

macOS builds are ad-hoc signed and not notarised, so clear the quarantine flag after
unzipping:

xattr -dr com.apple.quarantine /Library/Audio/Plug-Ins/Components/VarispeedDelay.component

Tested on

• macOS / Logic Pro
• Windows / FL / Ableton

Known gaps

• No factory presets yet — the machinery is in place, the content is not.

VarispeedDelay 0.1.0

First release. A delay where every repetition is replayed at a different tape speed —
pitch and duration change together, and slow repetitions overlap the following ones
instead of being cut short.

• time 0.1 ms – 20 s free, or tempo-synced up to 2 bars with PPQ-anchored boundaries
• speed 1/4x – 4x with a 3x3 shortcut grid: octaves plus fourths and fifths
• feedback 0–2, RAW (varispeed compounds each generation) or STABLE (it does not)
• GRID / TAPE spacing, REGRID / BEND response to time changes
• 7-band graphic EQ in the repetition path, soft clip in the recycle path

See USAGE.md for what each control does and which behaviours are deliberate.

Apple Silicon only (arm64); these are not universal binaries.

Ad-hoc signed, not notarised, so Gatekeeper will block them on first use. Clear the
quarantine flag after unzipping:

xattr -dr com.apple.quarantine /Library/Audio/Plug-Ins/Components/VarispeedDelay.component

Known gaps

• No factory presets yet — the authoring and embedding machinery is in place, but the
  preset content still has to be dialled in by ear.
• Not yet validated with auval, pluginval or a DAW.
• Glide, bend limits, clip threshold and interpolator order are at their design defaults
  and have not been tuned by ear.
