FLAC audio decoding and encoding for Zig via the battle-hardened xiph.org libflac

• Zero-fuss installation, cross-compilation at the flip of a switch, and broad platform support.
• Encoding & decoding support

Experimental

This is an experimental project according to our stability guarantees:

When a project has an experimental warning, it means all bets are off. You should carefully read the warning to understand why the project is experimental, and assume the worst.

Tracking issue: https://github.com/hexops/mach/issues/959

Getting started

Create a build.zig.zon in your project (replace LATEST_COMMIT with the latest commit hash):

.{
    .name = "mypkg",
    .version = "0.1.0",
    .dependencies = .{
        .mach_flac = .{
            .url = "https://pkg.machengine.org/mach-flac/LATEST_COMMIT.tar.gz",
        },
    },
}

Run zig build in your project, and the compiler will instruct you to add a .hash = "..." field next to .url:

note: expected .hash = "12209838fcfb7a77d2d6931efdc7448c033a1b7dad11d082c94bbeeba9d1038cd311",

Then use the dependency in your build.zig:

pub fn build(b: *std.Build) void {
    ...
    exe.root_module.addImport("mach-flac", b.dependency("mach_flac", .{
        .target = target,
        .optimize = optimize,
    }).module("mach-flac"));
}

You can now use it in your src/main.zig file:

const flac = @import("mach-flac");

See here for example code.

Ran into trouble?

Triple-check you followed the build.zig.zon instructions correctly, it’s easy to mess that part up.
