Frequently Asked Questions
What types of noise does this remove?
The tool uses spectral gating to remove consistent background noise: HVAC hiss, fan noise, room hum, computer fan noise, electrical hum (50/60 Hz), and microphone self-noise. It works best on steady-state noise rather than sudden sounds like claps or speech from another person.
Will noise reduction affect my voice quality?
At Standard strength, voice quality is well preserved. Aggressive mode removes more noise but may add a subtle artifact (sometimes described as a "watery" sound) to the voice. If you notice artifacts, try Standard or Subtle strength instead.
Is it free? Any limits?
100% free with no account required. Files up to 500 MB, no limit on number of files. Your audio is processed on a secure server and deleted within 1 hour.
Which output format should I choose?
MP3 is best for sharing and uploading to podcast hosts. WAV or FLAC are best if you'll continue editing in a DAW. M4A is ideal for Apple devices and iTunes.
