| Latency | The FAQ says accent-changing effects are designed around 135 ms algorithmic latency and that actual latency depends on model, CPU, audio settings, and processing cores. | The README lists under 200 ms end-to-end latency on a modern GPU. |
| Local processing | The product page says local compute processes audio on the user's machine and that voice data stays on the PC; cloud compute can offload processing to Altered servers. | The project says audio processing happens on the user's machine and audio never leaves the computer. |

In their own words
Altered Real-Time Pro
Altered Real-Time Pro is a desktop virtual microphone that routes AI-processed speech into voice and video communication apps. It runs on Windows and macOS and works with apps that accept microphone input, including Zoom, Google Meet, Discord, Skype, WhatsApp, games, and call-centre software. Its four feature areas address different audio needs: Isolate suppresses noise and competing speakers, Voice Skins change vocal identity, Accent Translation alters accents, and Euphonia restores voices. Processing can run locally on the user's machine, with the product page saying voice data stays on the PC, or Cloud Compute can offload work to nearby servers in the US, EU, or India. Cloud Compute costs $2 per hour of daily quota per month. The free plan provides 20 minutes of processing per day; paid plans start at $5/mo. Accent-changing effects are designed around 135 ms algorithmic latency, while actual latency depends on the model, CPU, audio settings, and processing cores. Enterprise includes team controls and priority support.
