v0.2.0-hip (Windows HIP)

audio.cpp for Windows + AMD GPU (HIP/ROCm)

Prebuilt audiocpp_cli / audiocpp_server binaries for AMD GPUs.
No ROCm/HIP SDK installation required — the ROCm runtime DLLs and GPU kernel
libraries are bundled in the package. A recent AMD Adrenalin driver is the only
prerequisite. A CPU fallback backend is included in the same binaries
(--backend cpu).

Which package do I need?

Package	ROCm	Supported GPUs (gfx)
audiocpp-bin-win-hip-rocm7.1-x64.zip	7.1	gfx1100, gfx1101, gfx1103, gfx1150, gfx1151, gfx1200, gfx1201
audiocpp-bin-win-hip-rocm6.4-x64.zip	6.4	gfx1100, gfx1101, gfx1102, gfx1103, gfx1150, gfx1151, gfx1200, gfx1201

• RX 7600 (gfx1102): use the ROCm 6.4 package. ROCm 7.1 ships no hipBLASLt
  kernels for gfx1102, so the 7.1 package cannot serve it.
• Radeon 780M / Strix Point / Strix Halo iGPUs (gfx1103 / gfx1150 / gfx1151):
  either package works.
• RDNA4 (RX 9070 series, gfx1200/1201): either works; the 7.1 package is
  recommended (better-tuned RDNA4 kernels).

Quick start

# TTS via HIP backend
.\audiocpp_cli.exe --backend hip --task tts --family <family> --model C:\path\to\model [options]

# Server
.\audiocpp_server.exe --config C:\path\to\server.json

--backend rocm is accepted as an alias for --backend hip.

Keep all DLL files and the rocblas\ and hipblaslt\ directories next to the
.exe files — the math libraries locate their kernel files relative to the DLL
path. If GPU initialization fails, update your AMD driver first.

Notes

• Built on GitHub Actions from this fork's main (workflow:
  .github/workflows/release-hip.yml); see
  docs/build/windows-hip-distribution.md for the full build/packaging story.
• HIP build support itself is merged upstream
  (0xShug0/audio.cpp#153);
  these prebuilt packages are published from the fork because upstream does not
  maintain AMD releases (no hardware to test).
• Windows 10/11 x64 only. Model files are not included; download them separately
  per docs/models/.
