Run-time of the data history buffers for interpolating the propagation delay comparing different methods. Additionally, the data is set in relation to the available time to process an audio block (1024 samples at 44.1 kHz).
| Absolute | Relative | |
|---|---|---|
| Interpolation | Run-time | Run-time |
| Sample-and-hold | 0.1440 μs | 6.20 × 10−6 |
| Nearest-neighbor | 0.1435 μs | 6.18 × 10−6 |
| Linear | 0.1527 μs | 6.58 × 10−6 |
| Cubic spline | 1.668 μs | 7.18 × 10−5 |
