These results were obtained by running a batch of test MPX recordings through redsea at a real-time speed on different platforms.
| Computer | CPU | Redsea version | % CPU |
|---|---|---|---|
| Raspberry Pi | 700 MHz ARMv6 | 0.17.0 | 40–45 % |
| Raspberry Pi 3B | ARMv7 | 1.0-SNAPSHOT | 11 % |
| 2013 Macbook Pro | 2.8 GHz i7 | 0.17.0 | 0.6 % |
| 2021 Macbook Pro | M1 Pro | 1.0-SNAPSHOT | 1.1 % |
The following noise performance results refer to the percentage of groups decoded in a few different field recordings. Redsea's noise performance is platform-dependent. This could be due to small differences in the liquid-dsp floating-point algorithms for ARM vs. x86.
Pilot SNR is used as a measure of noisiness because it's relatively simple to calculate. Redsea does not use the pilot tone.
| Test file | Pilot SNR | % groups ARM | % groups i7 |

| vikerraadio-171k.s16 | +51 dB (Excellent) | 99.8 | 99.8 |
| raw-yleyksi-171k.s16 | +36 dB | 99.1 | 99.5 |
| puhe.s16 | +30 dB | 2.7 | 63.1 |
| raw-ylesuomi-171k.s16 | +26 dB | 64.5 | 94.0 |
| nova.s16 | +21 dB (Noisy) | 0.0 | 8.5 |
