"x64" Branch

Windows "x64" branch binaries can be found in under Releases.

The latest builds for Windows can be found here:

• x86
• x64
• x64-avx2
• arm64

There are both MSI-based and EXE-based installers. The latter makes sure the runtime prerequisites are installed before installing.

To manually install the prerequisites, make sure a recent version of the Microsoft Visual C++ Redistributable for Visual Studio 2015-2019 is installed. If not already available, the installers can be downloaded from:

• vc_redist.x86.exe (32-bit)
• vc_redist.x64.exe (64-bit)
• vc_redist.arm64.exe (ARM64)

The "x64" branch is based on Audacity's master branch and also:

• Supports targeting 64-bit Windows (both x64 and ARM64)
• The Noise Generator supports an optional Gaussian white noise source in addition to the existing uniform white noise source.
• A "whiteg" command has been added to Nyquist that produces white Gaussian noise to complement the existing "white" command for producing uniform white noise.
• Uses C++'s <random> infrastructure instead of Microsoft's broken (and deprecated) implementation of C's rand(). The xoshiro256** PRNG is used as the random engine (adapted from the reference xoshiro256starstar.c).
• Better support for handling high-DPI displays. There are still parts of the UI that need to be fixed, but on Windows it remains usable up to 150% or so. Changing the scale while the application is running only works for some parts of the UI.
• Builds both MSI and EXE based installers.
• Uses Ninja for the CI builds (Windows, macOS, and Ubuntu).

Binaries built from the "x64" branch are available for 32-bit Windows (x86), 64-bit Windows (x64), 64-bit Windows (x64) with AVX2 support, and Windows 10 on ARM (ARM64).

Note that the 64-bit AVX2 build requires both a CPU that supports those extensions and Window 7 SP1 or later since earlier versions of Windows do not support the AVX2 extensions.

While the ARM64 binaries are provided, they have not been tested extensively.
