Specifying the Recording Quality

You can specify the audio quality with which the recording will be made.

The audio quality setting is a combination of the sampling rate and the Rec Mode. The audio quality will affect the size of the file, and will also affect the length of time over which recording can take place with an SD card.

Consider whether audio quality or length of recording are more important for your situation, and choose the quality that’s appropriate for you.

“Recording Settings for Various Situations” (p. 58)

Sampling Rate

(Default in bold)

44.1kHz

48.0kHz

Sampling rate value

88.2kHz

96.0kHz

Higher sampling rates will provide higher audio quality. You’ll need to use a high sampling rate if you want to accurately reproduce the high-frequency range.

•Higher sampling rate settings will increase the size of the file, and will shorten the available recording time.

•If you are recording audio material that you’ll be editing into a video production, we recommend that you use the 48 kHz sampling rate.

•The R-05 is not able to convert the sampling rate of a recorded file.

If the sampling rate is 88.2 kHz or 96.0 kHz, you cannot choose MP3 or WAV+MP3 as the Rec Mode (p. 41).
