Audacity

Audacity is the world's most popular audio editing and recording app. It is widely used in Windows. Now, support has been added for building on ARM64. Audacity uses Conan build system to link against its dependencies. Various packages like RapidJSON, wxWidgets, opus file had to be updated inorder for Audacity to be built natively on Windows on Arm64. Audacity builds need MSYS2. Currently. MSYS2 is a work in progress and therefore the environment variable needs to be set birder for MSYS2 (emulated) shell to be used instead.

Requirements:

A development machine running Windows ARM64 (Surface, Thinkpad, Project Volterra, Windows VM on Apple M2):
Setup necessary build tools. Follow the steps from wenv
Download Audacity source from GitHub - audacity/audacity: Audio Editor

Compilation

On a MSYS2 bash shell

conan profile detect
cat > global.conf << EOF
tools.microsoft.bash:path=c:/wenv/msys2/msys64/usr/bin/bash.exe
tools.microsoft.bash:subsystem=msys2
EOF
conan config install global.conf
rm global.conf

Once the environment configuration is set up, building a binary is simple as following these steps :

mkdir build
cd build
cmake -A arm64 -S ../ -B .
cmake --build .
(From an administrator cmd shell)
cmake --build . --target install --config Release

Continuous Integration

Audacity team uses GitHub action exclusively to build regular binaries for all targets. Lack of Arm64 Github runners has not enabled Windows on Arm64 builds currently.

Binary Availability

Audacity is expected to include Windows on Arm64 support in 3.5 release. However, until Github runners for Arm64 are available, we do not expect a binary published.
