As a professional audio processing tool, Demucs has designed a complete hardware acceleration program. It not only supports mainstream computing platforms, but also intelligently adapts to various hardware environments to ensure that users get the best performance experience.
Key technical features include:
- Multi-GPU support: Compatible with NVIDIA CUDA, Intel Arc and Apple MPS architectures.
- Heterogeneous computing: automatic switching of CPU/GPU processing, forced CPU mode via -d cpu parameter
- Multi-Core Optimization: Adopt -j parameter to support multi-threaded CPU processing, improve performance in pure CPU environment
- Memory management: provide segment parameter to adjust the slice size, to solve the memory limitation of the low configuration device.
In a test environment with 16GB of RAM + i7 processor, the separation time for 3-minute audio can be controlled within 5 minutes, while the RTX 3060 graphics card reduces the processing time to 1 minute. This flexible hardware adaptation solution enables Demucs to run stably on a wide range of computing devices.
