When Krisp is the better choice
- Your actual problem is noise — a café, a keyboard, a room with an echo. Subtl does nothing about how you sound.
- You want accent conversion or a cleaner outbound voice.
- You are on Windows, where Krisp has been shipping for years.
Krisp is a good product. If one of those describes you, buy theirs.
Questions
- Do they conflict if both are running?
- No. Krisp sits on the microphone path going out; Subtl reads what comes in and what your microphone hears. Running both is fine.
