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 Sample Rate
(sampling rate) and the Rec Mode. The audio quality will aect the
size of the le, and will also aect the length of time over which
recording can take place with an microSD card.
Consider whether audio quality or length of recording are more
important for your situation, and choose the quality that’s
appropriate for you.
Sample Rate
(Default in bold)
Sample Rate
44.1 kHz
48.0 kHz
88.2 kHz
96.0 kHz
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.
MEMO
5 Higher sampling rate settings will increase the size of the
le, and will shorten the available recording time.
5 If you are recording audio material that you’ll be editing into
a video production, we recommend that you use the 48.0
kHz sampling rate.
5 The R-07 is not able to convert the sampling rate of a
recorded le.
NOTE
5 If this setting is 88.2 kHz or 96.0 kHz, the only choices for Rec
Mode are WAV-16 bit and WAV-24 bit.
Rec Mode
(Default in bold)
Rec Mode
2xWAV-16bit
2xWAV-24bit
WAV+MP3
MP3-64kbps
MP3-96kbps
MP3-128kbps
MP3-160kbps
MP3-192kbps
MP3-224kbps
MP3-320kbps
WAV-16bit
WAV-24bit
WAV les allow higher-quality recording than MP3 les.
If you choose MP3, the le 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 le size, shortening the available
recording time.
WAV+MP3 simultaneously creates both a WAV le and an MP3 le.
MEMO
5 Some software such as Windows Media Player cannot play
back 24-bit WAVE les.
NOTE
5 2xWAV-16 bit, 2xWAV-24 bit, MP3 and WAV+MP3 can be
selected only if the Sample Rate is 44.1 kHz or 48.0 kHz.
5 If you select WAV+MP3, the setting is xed at WAV-16 bit and
MP3-128 kbps.

Setting the Sample Rate and Rec Mode
1. Press [SCENE] to access the “Scene” screen.
2. Use [ ]/[ ] to move the cursor to Sample Rate
setting, and use [ ]/[ ] to change the setting.
3. Use [ ]/[ ] to move the cursor to Rec Mode
setting, and use [ ]/[ ] to change the setting.
4. Press [SCENE] to return to the main screen.
2xWAV (Dual level recording)
By choosing 2xWAV- as the Rec Mode, you can simultaneously
record at the specied input level (p. 17) and at an input level
approximately 20 dB lower than that input level. This setting is
recommended if there is a possibility that the recorded sound
might distort when the volume during actual recording is louder
than you expected.
When you record, two les are created. The examples below are
for when the le name is R07_0010.WAV.
R07_0010.WAV Recorded at the specied input level
R07_0010L.WAV
Recorded at an input level 12 dB lower
than the specied level
