# IC Recorder ICD-PX333/PX333F

## The recorded file is noisy and is hard to understand.

- Noise from the recording environment other than the human voice is recorded.

  If you set the noise cut function to “Maximum” or “Medium,” the IC recorder reduces the extraneous noise, such as mechanical noise from projectors or air-conditioners.

  This function reduces noise in the entire bandwidth, therefore the IC recorder is able to play back the human voice clearly.
