Question 1

Why is keyboard noise so hard to remove from recordings?

Accepted Answer

Keyboard noise is particularly challenging because it's transient (sharp, brief bursts) rather than consistent background noise. Traditional noise reduction algorithms work by identifying a consistent noise profile and subtracting it — but each keystroke is a brief, unpredictable event with frequency content that overlaps with speech (especially sibilants and consonants). AI-based tools handle this better than traditional spectral subtraction, but complete removal without artifacts is difficult when typing is heavy and continuous.

Question 2

What's the best way to prevent keyboard noise in recordings?

Accepted Answer

Prevention is far more effective than removal. Options in order of effectiveness: (1) stop typing when recording is rolling; (2) use a noise gate in your recording software to gate the mic when you're not speaking; (3) switch to a quieter keyboard (low-profile membrane, silent mechanical switches like Cherry MX Silent Red, or rubber dome); (4) use a directional microphone with the capsule pointed away from the keyboard; (5) add a desk mat under the keyboard to reduce case resonance. For OBS streaming, Krisp or RTX Voice's real-time noise suppression handles keyboard bleed effectively.

Question 3

Does Krisp remove keyboard noise?

Accepted Answer

Yes — Krisp is specifically trained to suppress keyboard noise in real time, making it one of the most effective real-time solutions for this problem. For live streaming and calls, Krisp's keyboard noise suppression is excellent. For recorded audio files where you need post-processing, Voice Isolate handles noise reduction on the uploaded file. If your workflow involves both live streaming and reviewing recordings, combining Krisp for real-time use and Voice Isolate for post-production cleanup covers both scenarios.

Question 4

What microphones are least prone to picking up keyboard noise?

Accepted Answer

Dynamic microphones (like the Shure SM7B or Electro-Voice RE20) are significantly less sensitive to ambient noise than condenser microphones, making them naturally better at rejecting keyboard noise from a distance. Any directional (cardioid) mic positioned close to your mouth (15–20 cm) picks up proportionally less keyboard noise than the same mic at arm's length, because the voice-to-keyboard ratio improves with proximity. Desk-mounted arm mounts (like the Rode PSA1) let you position the mic optimally without it touching the desk where keyboard vibration transmits.

Remove Keyboard Typing Noise from Audio

Keyboard typing during recordings — especially mechanical keyboards — creates loud percussive clicks that distract listeners and are hard to remove after capture.
