The recorded file is noisy and is hard to understand.

  • Ambient noise is recorded as well as human voices.

    If you apply the Clear Voice function (“Clear Voice 1” or “Clear Voice 2,”) to the playback audio, ambient noise in all frequency bands (noise from projectors or air conditioners, etc.) will be reduced to make human voices distinctive, and you will hear human voices more clearly.

    While playback with the built-in speaker or playback of the files in “ Music” is in progress, however, the Clear Voice function does not work.
