ABOUT

Broadcurve is a passive program equalizer inspired by the original Pulse
Techniques EQP-1A. It combines interacting low-frequency boost and attenuation,
a broad high-frequency boost section, high-frequency attenuation, and a
modelled make-up amplifier path.

Broadcurve is an independent Ocvex product. It is not
affiliated with or endorsed by the manufacturer of the original hardware.

SYSTEM REQUIREMENTS

Plug-in format:
  - VST3 audio effect/equalizer
  - 64-bit host application

Windows:
  - Windows 10 version 1607 or later
  - x86-64 processor and x86-64 VST3 host
  - 32-bit Windows and 32-bit hosts are not supported

macOS:
  - Intel Mac: macOS 10.15 Catalina or later
  - Apple Silicon Mac: macOS 11 Big Sur or later
  - Universal x86_64/arm64 bundle; a native Apple Silicon host does not require
    Rosetta

The processor path is validated at 44.1, 48, 88.2, 96, 176.4, and 192 kHz in
mono and stereo configurations. Actual sample-rate and channel availability is
controlled by the host application and audio device.

HOST COMPATIBILITY

The host must support 64-bit VST3 effects. This package does not contain VST2,
Audio Unit, AAX, or standalone application formats.

RUNTIME DEPENDENCIES

No separate Microsoft Visual C++ Redistributable, .NET runtime, Java runtime, or
JUCE runtime is required. The Windows package links the MSVC runtime statically.
The macOS package uses only operating-system frameworks. All plug-in code and
required resources are contained in the Broadcurve.vst3 bundle.

INSTALLATION

Broadcurve is distributed without an installer. Close your audio
applications, then copy the complete Broadcurve.vst3 bundle to a standard
VST3 folder.

Windows, all users:
  C:\Program Files\Common Files\VST3

macOS, all users:
  /Library/Audio/Plug-Ins/VST3

macOS, current user:
  ~/Library/Audio/Plug-Ins/VST3

MACOS SECURITY APPROVAL

By project policy, macOS releases are distributed without Apple Developer ID
signing or notarisation. This is intentional and is not expected to change for
the current distribution model. macOS may therefore block Broadcurve during
the first plug-in scan. Close the audio application and use one of the following
approval methods only after verifying that the archive came from the official
Ocvex source and that its published SHA-256 checksum matches.

Option 1 - System Settings:
  1. Open System Settings > Privacy & Security.
  2. In the Security section, click Open Anyway for Broadcurve.
  3. Confirm with your macOS login password when requested.

Option 2 - Terminal:
  For a current-user installation, run:
    xattr -dr com.apple.quarantine \
      ~/Library/Audio/Plug-Ins/VST3/Broadcurve.vst3

  For an all-users installation, run:
    sudo xattr -dr com.apple.quarantine \
      /Library/Audio/Plug-Ins/VST3/Broadcurve.vst3

After approving the plug-in, restart the audio application and run a full
plug-in rescan. If the application blacklisted Broadcurve after the first
attempt, clear or reset its failed plug-in list before rescanning.

Start your audio application and run its plug-in rescan if Broadcurve does
not appear automatically. The plug-in is classified as an audio
effect/equalizer.

Do not copy individual files out of the Broadcurve.vst3 bundle. The bundle
must remain complete and retain its directory structure.

UNINSTALLATION

Close your audio applications and remove Broadcurve.vst3 from the VST3
folder where you installed it. Broadcurve does not install a background
service or a separate uninstaller.

CONTROLS

LOW FREQUENCY selects the low-frequency corner used by both BOOST and ATTEN.
HIGH FREQUENCY BOOST provides frequency, amount, and bandwidth controls.
HIGH FREQUENCY ATTEN selects the attenuation frequency and amount.
EQ IN bypasses the passive EQ sections while keeping the make-up path active.
ANALOG NOISE enables the optional modelled noise contribution.
OUTPUT adjusts the final output trim.

Double-click a rotary control to restore its default value.

LICENCE

personal, educational, professional, and commercial audio production.

version, Broadcurve version, sample rate, and the steps needed to reproduce
it.
