Our online implementation is based on pure python code with some optimization of the streaming convolutions and transposed convolutions. We benchmark this implementation on a quad-core Intel i5 CPU at 2 GHz. The Real-Time Factor (RTF) of the proposed models are:
| Model | Threads | RTF |
|---|---|---|
| H=48 | 1 | 0.8 |
| H=64 | 1 | 1.2 |
| H=48 | 4 | 0.6 |
| H=64 | 4 | 1.0 |
