# audio.cpp server (0xShug0/audio.cpp) for VibeVoice-ASR-Streaming on nh3-ml1.
# The release's Linux CUDA build ("cuda12.8-colab") is a bare binary that needs the
# CUDA 12 runtime libs (cudart, cublas, cufft, nccl) plus libgomp. This image
# supplies them, plus libsoxr (without it audio.cpp falls back to linear
# resampling for the 16k→24k step). Built locally on the host; not pushed.
