Recording
WAV files allow higher-quality recording than MP3
files. If you choose MP3, the file size will be smaller
than WAV, allowing you to record for a longer length
of time. Higher settings for “bit” or “bps” will increase
the file size, shortening the available recording time.
WAV+MP3 simultaneously creates both a WAV file
and an MP3 file.
Some software such as Windows Media Player
cannot play back 24-bit WAVE files.
• MP3 and WAV+MP3 can be selected only if the
sampling rate is 44.1 kHz or 48.0 kHz.
• If you select WAV+MP3, the setting is fixed at
WAV-16 bit and MP3-128 kbps.
