Key optimizations to reduce real-time conversion latency include:
Hardware configuration
- Use of NVIDIA GPUs (e.g. RTX 3060 and above) dramatically accelerates processing
- Ensure that the latest version of the CUDA driver is installed (recommended 12.4)
parameterization
- Reduce the number of diffusion steps to between 4 and 10 (mass and delay balance)
- Set Block Time to about 0.18 seconds
- Enable FP16 half-precision calculations (
--fp16 True)
system optimization
- Routing signals using virtual audio devices such as VB-CABLE
- Close other programs that consume GPU resources
- Setting High Performance Power Mode for Windows Systems
After optimization on RTX 3060, the latency can be controlled at around 430 ms, which fully meets the demand of real-time scenarios such as live broadcasting and gaming etc. Latency will be significantly higher in CPU mode, and it is recommended to use it for testing only.
