add: absorb soprano_to_rvc as regular subdirectory
Voice conversion pipeline (Soprano TTS → RVC) with Docker support. Previously tracked as bare gitlink; removed .git/ directories and absorbed into main repo for unified tracking. Includes: Soprano TTS, RVC WebUI integration, Docker configs, WebSocket API, and benchmark scripts. Updated .gitignore to exclude large model weights (*.pth, *.pt, *.onnx, *.index). 287 files (3.1GB of ML weights properly excluded via gitignore).

## Key Design Decisions
|
||||
|
||||
### Why Two Containers?
|
||||
|
||||
**CUDA and ROCm runtimes cannot coexist in a single container.** They have:
|
||||
- Conflicting driver libraries (libcuda.so vs libamdgpu.so)
|
||||
- Different kernel modules (nvidia vs amdgpu)
|
||||
- Incompatible system dependencies
|
||||
|
||||
The dual-container approach provides:
|
||||
- Clean runtime separation
|
||||
- Independent scaling
|
||||
- Better resource isolation
|
||||
- Minimal latency overhead (~1-5ms Docker networking vs ~700ms ZMQ serialization)
|
||||
|
||||
### Performance Preservation
|
||||
|
||||
The Docker setup maintains bare metal performance:
|
||||
- ZMQ communication already exists (not added by Docker)
|
||||
- GPU passthrough is direct (no virtualization)
|
||||
- Network overhead is negligible (localhost bridge)
|
||||
- Expected performance: **0.95x realtime average** (same as bare metal)
|
||||
|
||||
## Usage
|
||||
|
||||
### Build and Start
|
||||
|
||||
```bash
|
||||
cd soprano_to_rvc
|
||||
|
||||
# Option 1: Quick start (recommended for first time)
|
||||
./start_docker.sh
|
||||
|
||||
# Option 2: Manual
|
||||
./build_docker.sh
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
### Test
|
||||
|
||||
```bash
|
||||
# Health check
|
||||
curl http://localhost:8765/health
|
||||
|
||||
# Test synthesis
|
||||
curl -X POST http://localhost:8765/api/speak \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"text": "Hello, I am Miku!"}' \
|
||||
-o test.wav
|
||||
|
||||
ffplay test.wav
|
||||
```
|
||||
|
||||
### Monitor
|
||||
|
||||
```bash
|
||||
# View logs
|
||||
docker-compose logs -f
|
||||
|
||||
# Check status
|
||||
docker-compose ps
|
||||
|
||||
# GPU usage
|
||||
watch -n 1 'docker exec miku-soprano-tts nvidia-smi && docker exec miku-rvc-api rocm-smi'
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Before first run, verify GPU device IDs in `docker-compose.yml`:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
soprano:
|
||||
environment:
|
||||
- NVIDIA_VISIBLE_DEVICES=1 # <-- Your GTX 1660 device ID
|
||||
|
||||
rvc:
|
||||
environment:
|
||||
- ROCR_VISIBLE_DEVICES=0 # <-- Your RX 6800 device ID
|
||||
```
|
||||
|
||||
Find your GPU IDs:
|
||||
```bash
|
||||
nvidia-smi -L # NVIDIA GPUs
|
||||
rocm-smi # AMD GPUs
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
### 1. Test Containers ✅ READY
|
||||
```bash
|
||||
./start_docker.sh
|
||||
curl http://localhost:8765/health
|
||||
```
|
||||
|
||||
### 2. Integration with Discord Bot
|
||||
Add to main `docker-compose.yml`:
|
||||
```yaml
|
||||
services:
|
||||
miku-voice:
|
||||
image: miku-rvc:latest
|
||||
# ... copy from soprano_to_rvc/docker-compose.yml
|
||||
```
|
||||
|
||||
Update bot code:
|
||||
```python
|
||||
response = requests.post(
|
||||
"http://miku-rvc-api:8765/api/speak",
|
||||
json={"text": "Hello from Discord!"}
|
||||
)
|
||||
```
|
||||
|
||||
### 3. Test LLM Streaming
|
||||
```bash
|
||||
python stream_llm_to_voice.py
|
||||
```
|
||||
|
||||
### 4. Production Deployment
|
||||
- Monitor performance under real load
|
||||
- Tune configuration as needed
|
||||
- Set up logging and monitoring
|
||||
- Configure auto-restart policies
|
||||
|
||||
## Performance Expectations
|
||||
|
||||
Based on 65 test jobs on bare metal (Docker overhead minimal):
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| **Overall Realtime** | 0.95x average, 1.12x peak |
|
||||
| **Soprano Isolated** | 16.48x realtime |
|
||||
| **Soprano via ZMQ** | ~7.10x realtime |
|
||||
| **RVC Processing** | 166-196ms per 200ms block |
|
||||
| **Latency** | ~0.7s for ZMQ transfer |
|
||||
|
||||
**Performance by text length:**
|
||||
- Short (1-2 sentences): 1.00-1.12x realtime ✅
|
||||
- Medium (3-5 sentences): 0.93-1.07x realtime ✅
|
||||
- Long (>5 sentences): 1.01-1.12x realtime ✅
|
||||
|
||||
**Notes:**
|
||||
- First 5 jobs slower due to ROCm kernel compilation
|
||||
- Warmup period of 60-120s on container start
|
||||
- Target ≥1.0x for live voice streaming is achievable after warmup
